Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical nail for a Jacquard machine, and in particular, the vertical nail has a pair of knives that are movable in opposite directions and pass each other, and a vertical nail that can be controlled by a horizontal needle (main needle). the nail is not configured bipedally, the vertical nail is provided with two main hooks that are receptively engaged in entrainment members provided on the pair of knives;
This type of jitz card machine is equipped with a free range to allow the horizontal needle to move and adjust the vertical nail to a position where the main hook is not received and engaged with the driving member, and is suitable for double-acting, fully opening type machines. Regarding vertical nails.

In the known conventional double-acting full-opening jacquard machine, the vertical nails, which are pushed and controlled by horizontal needles, are constructed in the form of two legs, each leg is provided with a main hook, and one leg is provided with a lock. A locking hook is provided.

The main hook is attached to a pair of knives that can be moved vertically oppositely and pass each other, and the vertical nail is lifted from the descending opening position to the ascending opening position by these moving knives.

On the other hand, the locking hook belongs to a stationary locking knife that is separate from the moving knife, and remains in the ascending opening position where the vertical nail is lifted by the locking knife. useful for.

A disadvantage of this type is that when a pair of counter-moving knives pass each other, care must be taken to ensure that the peg, which is moved downward from the ascending opening position to the descending opening position, is not caught by the rising knife. However, in order to ensure that this condition is maintained, the pushing control of the vertical nail by the horizontal needle must be maintained until the time when the pair of knives pass each other. This creates an unfavorable movement condition in the reading mechanism, which requires approximately half a shed stroke, corresponding to about 180' of crankshaft rotation, to move the transverse needle along with the card, and that maintenance for such a long period of time At the point of contact between the horizontal needle and the vertical nail, a large amount of friction occurs which has a disadvantageous effect on the movement of the vertical nail and the vertical nail that presses it.

In order to overcome this drawback, there are some types in which a pair of counter-moving knives are shifted vertically so that they do not pass through each other, but this requires the vertical nail to be made that much longer. This is by no means an advantageous solution, since it has the effect of increasing the instability of its motion and increases the overall height of the machine accordingly.

Therefore, an even more advantageous solution was proposed in Japanese Patent Application Laid-open No. 52-214.
It is known from the specification of No. 62 (Japanese Patent Application No. 51-88976).

According to this, a pair of knives that are movable in opposite directions and pass each other are arranged parallel to a horizontal needle (main needle),
The illuminator is not configured in a bipedal shape, but is provided with two main hooks belonging to the pair of knives, and is placed between the pair of knives.

The pair of knives are provided with driving members spaced apart from each other in the knife longitudinal direction (lengthwise direction) to receive the main hook of the light, and the light has a free range between the driving members along the knife. It is said that the movement can be adjusted up to.

According to this, the push adjustment control movement by the horizontal needle of the illumination is
along the longitudinal axis of the knife, as opposed to previously known conventional jacquard machines which are carried out at right angles to the longitudinal axis of the knife. It is a requirement that it be implemented.

The entraining member of the knife is configured such that the entraining surface can entrain the main hook belonging to the instrument when the instrument changes its shed position together with the main hook of the instrument; The main hook resting on top slides on this entrainment surface, so that the light contacts the knife, while the free main hook is freed from the range of movement of another knife which is movable oppositely. It is assumed that

On the other hand, if the main hook of the light is located in the free range between the carrying parts of the knife, the light remains in its basic position.

However, in this known solution, when the main hook of the peg is carried by the driving member of the knife, the main hook is moved against the driving surface of the driving member in order to achieve release of the other free main hook from the range of movement of the other knife. Since the illumination is supposed to come into contact with the knife by sliding along the horizontal needle, at this time the illumination has at least a slight amount of force in the direction crossing the direction of push control by the horizontal needle (in the direction intersecting the knife). It is obvious that it is also necessary to tilt or bend the structure, and this point presents the greatest difficulty.

Concomitantly, in this embodiment, when releasing the main hook from the entraining member, it is difficult to smoothly escape and retreat the main hook from the entraining member, or the main hook is not above the knife. It corresponds to the edge or lower edge.

Therefore, it has drawbacks that may cause problems in smooth and reliable movement and high-speed operation that are expected in these respects.

That is, in the presented specification of the form of this solution:
Regarding the structural form of the knife driving member and the main hook of the vertical nail 2
Two examples are shown.

The first is that the entraining member projects with a lateral slope on the side of the knife, and on the upper side of the entraining member there is a recess in the knife, so that the main hook can be placed in the entraining face on the entraining member. By sliding downward and engaging within the recess, the illumination is brought into contact with the knife.

However, in this case, there is a problem in that when the main hook is released from the engagement, it is not smooth to release the engagement from the recessed portion of the main hook.

and secondly, the entraining member comprises an inclined part forming an entraining surface formed on the upper edge of the knife, and between the entraining members there is provided as a free range a rejection surface which is inclined in the opposite direction; In this case, the width of the amphibious hook of the terutsuke should be set larger than the inner distance between two adjacent knives, the main hook should be arranged in the shape of an arrowhead at the upper end of the terutsuke, and the lower part of the knife should be The edges can be beveled to act as rejection surfaces, so that when the main hook is on the entrainment surface of the upper edge of the knife, the main hook slides on the entrainment surface due to their inclination. When the main hook is on the oppositely inclined rejection surface of the upper edge of the rising knife, the main hook slides on the rejection surface and rejects the knife. When the knife moves away from the surface and passes through the illuminated main hook that remains in the lowered position, even if the lower edge of the knife touches the main hook, the impact is absorbed by the sloped shape of the lower edge of the knife. It is said to be eliminated by acting as a rejection surface.

However, in this case, the rejection surfaces of the upper and lower edges of the knife collide with the main hook of the vertical nail, and it is difficult to smoothly move the main hook away from the rejection surface, and even when this separation and transfer occurs, the illumination It is clear that there are drawbacks such as the need for tilting or bending, the impact caused by collisions, and the extremely unstable illumination that makes it susceptible to damage.

In both the first and second cases, it is commonly recognized that the fundamental difficulty is that the illumination must be tilted or bent due to the illumination being pulled towards the knife and coming into contact with it. It is.

The object of the present invention is to eliminate the above-mentioned drawbacks of the Jacquard machine of the type known from the specification of JP-A-52-21462, and to During the entrainment, the release of the other free main hook from the range of motion of the knife belonging to it can be realized without the peg coming into contact with the knife and therefore without the need for tilting or bending the peg. This aims to ensure smooth and reliable movement and high-speed operation, thereby increasing the efficiency of the machine.

According to the present invention, the vertical nail has two main hooks provided on both sides of the main body of the vertical nail so as to protrude obliquely downward in a direction opposite to each other. This is achieved by being pivotally connected to the main body of the vertical nail so as to be able to tilt integrally with each other.

In short, the two main hooks that protrude diagonally downward from both sides of the main body of the vertical nail are not fixed and unchangeable at their protruding angles, but are variably pivoted integrally with each other. When one main hook tilts upward with respect to the nail main body to increase the angle, the other main hook on the opposite side simultaneously and integrally tilts downward based on that angle to decrease the angle. It is assumed that it will be changed as follows.

As a result, when one of the main hooks is receptively engaged with the driving member of the knife associated with it, it is tilted upward by the tensile load applied to the vertical nail, and is brought into a dog-shaped state. The other free main hook tilts downward and comes into contact with the side surface of the main body of the vertical nail and is in a non-protruding state, and is retracted from the range of movement of the associated opposing knife and is not engaged with it. be.

Regarding this action, the main body of the vertical nail does not come into contact with the knife or the like provided with the driving member, and therefore there is no need to tilt or bend.

Therefore, the operation is smooth and reliable, high-speed operation is possible without problems, and the efficiency of the machine is increased.

In the present invention, the main body of the vertical nail is preferably formed as a flat rod, and the two main hooks are formed as integrated tongues with a constant angle between them, but if necessary, The main part of the vertical nail can be shaped like a round bar, and the main hook can be shaped like a bar.

The two main hooks protrude downward symmetrically from each other at the same height level relative to the main body of the vertical nail, and both form an inverted V shape like a chevron or an arrowhead. They may be placed in the same position without deviation, or in different positions with deviations from left and right.

If the two main hooks are well balanced with respect to each other around the axis relative to the main body of the vertical nail, when the two main hooks are released from the driving member, they will automatically recover from the tilted state. In order to be more effective, a restoring biasing spring is provided which acts between the main body of the vertical nail.

Providing this spring not only helps ensure the restoration of the main hook, but also helps prevent disturbances from tilting due to vibrations, etc., and is advantageous for high-speed operation.

This spring advantageously extends upwardly along its side from a support provided at a lateral location of the peg body and engages at its upper part in the pivot center of the two main hooks for the peg body. However, the present invention is not limited to this, and it may also be constituted by a coil spring arranged so as to bias the bidirectional hook into a balanced state at the pivot portion.

According to the embodiment of the double-acting full-opening jacquard machine using vertical nails of the present invention, the knives can be arranged parallel to the horizontal needle (main needle) or crossed (orthogonal). It can also be arranged.

In the case where the knife is arranged intersecting (orthogonal to) the horizontal needle, the driving member is not provided directly on the knife;
It is provided on an upright plate-like member attached so as to intersect (perpendicularly intersect with) the knife and protrude to the side of the knife.

In this case, the free range is also formed in the projecting distance provided between the knife of the plate-like member and the driver member.

The advantage of this case is that the arrangement pitch of the horizontal needles and vertical nails, which corresponds to the perforation pitch of the card, is in the thickness direction of the plate member relative to the knife, compared to the case where the knife is arranged parallel to the horizontal needles. Since the plate-like member can be formed fairly thin to maintain its required strength, the attachment pitch can be made quite small, and therefore the perforation pitch of the card can be made small without any problems. Regardless of the size of the knife, it can be made larger and the knife can be made considerably thicker and stronger, allowing reliable operation and high-speed operation without the risk of bending the knife, which greatly increases the efficiency of the machine, and furthermore, without the risk of damaging the knife. plate member,
Pitch adjustment, repair, and replacement of vertical nails and horizontal needles becomes easy.

In any case, the needle is disposed between two knives that are movable in opposite directions and pass each other, or between two plate-shaped members projecting from them, and is arranged opposite to each other on the sides of the knives or plate-shaped members. The two main hooks belonging to each case are suitably engaged and driven by the projecting driving element.

Then, the vertical needle is pushed and adjusted by the horizontal needle along the length of the pouf or along the plate-like member in the direction crossing the knife, and the main hook is moved between the knife-carrying members or with the knife of the plate-like member. When moved to the free range in the overhanging interval between the members, the main hook is retracted and released from the entraining member in its lateral direction and is no longer engaged and entrained, and this action prevents the illumination body from bending. It is carried out without the need for a slight tilt.

Here, the entraining member is formed as a tongue-like body projecting diagonally upwards on the side of the knife or plate-like member, suitable for receiving and entraining the main hook.

The width between the protruding tips of the two main hooks of the needle is
smaller than the inner distance between the two knives belonging to these or the plate-like members projecting from them, and larger than the distance between the mutual tips of the two accompanying members projecting oppositely from the two knives or plate-like members be taken as a thing.

In addition, the angle between the two main hooks of the needle and their respective protruding lengths, and the angle and length of the sideward protrusion of the driving member from the knife or plate-like member are determined by the distance between the knives or plate-like members. In addition, it is set appropriately based on the realization of reliable entrainment in relation to each other and the prevention of tilting or bending of the illuminated subject during entrainment.

Depending on this setting, when the main hook is carried by the carrying member, the illuminated subject may be pulled in the direction toward the carrying member and may be slightly tilted or bent, but even in this case, the illuminated subject may be shaped like a knife or a plate. When viewed from the standpoint of not making any contact with the member, and thus causing such contact, the tilting or bending is extremely minute and almost non-existent.

The present invention will be described below with reference to illustrated embodiments.

1 to 3 each show an embodiment of the cylindrical needle according to the invention, which is designated by the reference numeral 1, with respect to its upper part.

First, the embodiment shown in FIG. 1 shows an illumination main body 2 made of a flat bar, and two main hooks 3, 3 made of a flat tongue-like body provided at the upper end of the illumination main body 2. .

The two main hooks 3, 3 are symmetrically arranged diagonally downward at the same predetermined inclination angle, opposite to each other, on both sides of the lighting main body 2 in the thickness direction, at the same place at the same height level and without deviation in the left and right directions. It stands out.

The two main hooks 3, 3 are integrated with each other so that the angle between them based on the respective protruding inclination angles remains constant, and is formed into a single member forming an inverted V shape such as an arrowhead shape or a chevron shape. It is present in a notch 4 formed by cutting out one edge of the upper end of the lighting main body 2 in a stepped manner, and in the core part, the intermediate base of the integration of both main hooks 3.3 is connected to both main hooks 3. A single pivot 5 facing in a direction intersecting (orthogonal to) the protruding direction of the hook
It is pivoted by.

Here, the pivot 5 is extended from a protruding support part 6 consisting of a side edge, which is the remainder of the notch 4 of the lighting main body 2, onto the notch 4 in parallel with this, and the projecting part is connected to both main hooks. It is fitted into the center of the pivoting boss part 7 of the intermediate base of No. 3, 3, and is fixed to one of the support part 6 and the boss part 7, and is loosely fitted to the other. .

The pivoting boss portions 7 of both main hooks are slightly extended and protruded at the ends opposite to the projecting support portion 6 of the illumination main body.

The lower end of the protruding end of the boss is fitted into and supported by a support part 8 provided as a protrusion on the side of the lighting main body 2 below, so that the lower end is supported on the side of the lighting main body 2. The upper end of a rod spring 9 of fairly weak elasticity extending upwardly along the edge is fitted.

Here, the bar spring 9 is fixed to one of the boss portions 7 of both main hooks and the support portion 8 of the illumination main body, and is loosely fitted to the other.

Depending on the width dimensions of both the main hooks 3, 3 and the illumination main body 2, the upper ends of the bar springs 9 may be inserted without extending the ends of the boss portions 7 of the main hooks.

According to this configuration, the two main hooks 3°3 are normally balanced around the pivot shaft 5, and both are in a state of the same protruding inclination angle with respect to the lighting main body 2, and moreover, in this state, It is maintained at 9.

The two main hooks 3, 3 have a direction in which the downward protruding inclination angle relative to the illumination main body 2 changes around the pivot 5 at a fixed angle between them based on the downward protruding inclination angle with respect to the respective illumination main body 2. It can be tilted integrally.

Therefore, when either one of the hooks 3 is biased upward or downward by an external force, both main hooks 3, 3
are rotated and tilted simultaneously and integrally about the pivot shaft 5 in the biasing direction, and as a result, the protruding inclination angle of the two main hooks 3, 3 relative to the respective needle main bodies 2 changes on the one hand to dog or small. At the same time, at the same angle as that change angle, on the other hand, a small or dog change occurs.

Upon this angle change, an action is caused that causes the spring 9 to flex.

This angle change is substantially possible up to a maximum of a certain angle between the two main hooks 3, 3 based on the downwardly protruding inclination angle thereof.

That is, one main hook 3 is tilted downward in a direction in which the angle of the other integrated main hook 3 becomes smaller, so that the two hooks 3, 3 are mutually connected to each other until it comes into contact with the side surface of the needle main body 2. An upward tilting of the angular change relative to the needle main body 2 is possible up to an angle corresponding to the angle between the needles.

When this state is reached, the other main hook 3 that is in contact with the side surface of the needle main body 2 is laid down parallel to the contact surface, so that the main hook 3 protrudes substantially at a zero angle with respect to the main needle main body 2. There will be no.

In addition, when the main hook is tilted to the maximum angle change, the angle of the main hook on the side with the large angle must not exceed 90 degrees with respect to the main body of the needle, and it must be tilted diagonally downward as much as possible. Therefore, the angle between the two main hooks is set at an appropriate angle that does not exceed 90'.

Moreover, when the external biasing force that was applied to cause such a tilting state of angle change is removed, the two main hooks 3, 3 are balanced around the pivot shaft 5, and the main hooks 2, 3 change from the tilted state to the main needle body 2. The spring 9 naturally returns to its original state with the same downward protruding inclination angle, and this restoration is forced quickly and reliably by the elastic biasing force of the spring 9, which had been deflected, to return to its original position. It will be done.

Next, in the embodiment shown in FIG. 2, the upper end of the bar spring 9 is fitted into a recess 10 formed in a shallow vertical groove shape, such as a V-shape or a U-shape, on the end surface of the boss portion 7 of both main hooks. Other than this point, the structure and operation are similar to the embodiment shown in FIG. 1.

Next, in the embodiment shown in FIG. 3, the two main hooks 3, 3 that protrude obliquely downward on both sides of the needle main body 2 are made into separate members, and the upper end of the needle main body 2 is They are arranged in notches 4, 4 that are symmetrically formed on both the left and right edges of the section.

Therefore, even though the two main hooks 3.degree. 3 are at the same height level, they are located with a positional shift from side to side.

The main hooks 3, 3 have respective boss portions 7, 7 supported by pivot shafts 5 that loosely fit through the protruding support portion 6 located between the two notches 4, 4.

As a result, the amphibious hooks 3, 3 are connected and integrated via the pivot 5, and the angle between them remains constant, and the angle between them is reversed.
They are shaped like a letter and can be tilted simultaneously and integrally around a pivot 5 to change the protruding inclination angle with respect to the needle main body 2.

It goes without saying that a spring 9 for restoring the main hooks from the tilting movement may be provided.

Therefore, this embodiment is characterized in that there is a left and right deviation between the two hooks 3, 3, and except for this point, the structure and operation are basically the same as the embodiments shown in FIG. 1 or 2.

Next, four embodiments of the Jacquard machine using the above-mentioned vertical needles will be described.

The first embodiment shown in FIGS. 4 and 5, which corresponds to a double-acting, full-opening jacquard machine, shows a pair of knives 11, 11 that move vertically oppositely and pass each other. This knife serves to lift the needle 1.

The needle 1 used is the one shown in Fig. 1 or 2, in which both the main hooks 3, 3 are in the same position with respect to the main needle body 2 without left and right deviation, and the main hook protrudes between the two knives 11° 11. It is arranged with the direction facing the knife surface.

The needle 1 has both main hooks 3, 3 attached to both knives 1 belonging to the husband.
1.11 are properly received and engaged by two driving members 12, 12 which are protruded from the respective side surfaces of the rod so as to face each other at the same position without deviation.

The driving member 12 projects obliquely upward at a predetermined angle on both sides of the lower edge of the knife 11 (not necessarily the lower edge) so as to form a V-shape together with a member for driving an adjacent needle. It consists of hook-like tongue-like bodies that are provided at predetermined intervals as free ranges 13 in the length direction of the knife.

A cross needle (main needle) 14, which is essential to a reading device (not shown) for controlling the needle 1, extends parallel to the knives 11,11.

In Figure 1, the arrow indicates the longitudinal direction of the machine, and the knife 1
1.11 and the horizontal needle 14 both extend in the direction of this arrow.

Also arranged parallel to this direction is a fixed locking knife 15, which serves to keep the needle 2 lifted by the associated knife 11 or 11 in its upper shed position. .

This is a locking member 16 consisting of a diagonally upward hook-shaped tongue protruding from the side surface of the locking knife 15, and a diagonally downwardly protruding portion provided on the side of the lower intermediate portion of the cylindrical needle 1. This is done by receiving and engaging the locking hook 17.

However, in some cases, the locking knife 15 may be disposed intersecting (orthogonal to) the horizontal needle 14, and the locking member 1
It is also possible to provide that the locking hook 17 of the needle 1 is engaged directly with the upper edge of the locking knife 15 without the locking knife 15.

In addition, in the figure, 18 is a bottom plate, and 19 is a suspension string. With this construction, however, as shown in FIG. The combined main hooks 3 are tilted upward about the pivot 5 due to the tensile load applied to the needle 1, and are placed on the driving member 12 with a large angle change relative to the needle main body 2. captured and taken away.

Therefore, in this state, naturally, the entrainment action is realized without any contact between the needle main body 2 and the knife 11.
Therefore, there is no necessity for the needle main body 2 to be tilted or bent.

Moreover, the other free main hook 3 is tilted downward and is brought into a non-projecting state where it lies down against the side surface of the needle main body 2.

As a result, the other free main hook 3, due to its tilted, collapsed, non-protruding state, is able to move the knife, especially when the needle 1 tends to move down together with the other knife, as shown by the arrow in the figure. 11 and 11 pass each other, even if the vertical needle 1 is not pushed and controlled by the cross needle 14 at that point, the other rising knife 11 associated therewith is retracted and released from the movement range of the entraining member 12. Therefore, the needle 1 is not unintentionally brought into the upper shed position, and this is achieved without tilting or bending the needle body 2.

When such entrainment is released, that is, when the entrainment member 12 of the knife 11 separates from the main hook 3 with which it has been engaged, both main hooks remain in the main body 2 without tilting or bending. The hooks 3, 3 automatically restore from the tilted state.

Further, when the main hook 3 is in a position where it is moved away from the entraining member 12 in the lateral direction (direction along the knife), both main hooks 3, 3 are of course restored from the tilted state.

In any of the movements of releasing the entrainment, restoring the main hook from tilting, and moving the main hook away from the entrainment member to a lateral position, the main hook 2 is always connected to the knife 11 and the cross needle 14 from the beginning. While remaining stably located between the two knives 11, 11 without any tilting or bending action in the cross direction,
Furthermore, this can be easily and smoothly carried out without any obstacles such as the main hook 3 hitting the knife 11 and obstructing these movements.

These points will be easily understood in conjunction with the structure and function of the needle 1 described above.

The suppression adjustment control movement of the vertical needle 1 is carried out by the horizontal needle 14.
1, 11 in the longitudinal direction.

If this movement causes the two main hooks 3, 3 of the needle to be moved laterally into the free range 13 between the carrying parts of the knife and to be located here oppositely, the two main hooks 3, 3
are retracted from their respective associated driving elements 12.degree. 12 and are no longer in reception engagement, so that the needle 1 is not lifted up as a result of the vertical movement of the two knives 11, 11, but remains in its basic position.

This movement also causes the locking hook 17 to be released from the locking knife 15.

This movement does not require bending of the syringe 2, but is carried out by a slight lateral tilting along the length of the knife.

Next, in the second embodiment shown in FIGS. 7 to 9, the needle 1 shown in FIG. 3 is used, in which both main hooks 3, 3 are offset from the left and right with respect to the needle main body 2, Correspondingly, the two driving members 12, 12 of the two knives IL11 belonging to the two main hooks 3, 3, which are protruded from each other and opposite to each other, are not located at the same position, but are arranged with a shift in the knife length direction. has been done.

That is, the respective entraining members 12 are spaced apart from each other on either side of the knife 11 in the knife length direction with an offset corresponding to either of the two main hooks 3, 3.

Other than this point, there is a free range 13 between the entraining members;
The knives 11, 11 are arranged parallel to the horizontal needle 14, and other structures and functions are the same as in the first embodiment.

Next, in the third embodiment shown in FIG. 10 and FIG. 11, the knife 1 is
1 and 11 are arranged in a direction intersecting (orthogonal to) the horizontal needle 14.

The needle 1 used is the one shown in FIG. 1 or 2, in which both main hooks 3, 3 are in the same position on the left and right sides with respect to the needle main body 2.

Each of the two knives 11, 11 is provided with upright thin plate-like members 20 at a predetermined pitch, intersecting (orthogonal to) the knife (therefore, parallel to the horizontal needle) and protruding from the space between the knife and the adjacent knife on both sides of the knife. has been done.

A driving member 12 is provided at the projecting end of the plate-like member 20 and projects from both sides thereof.

There is a projecting interval between the knife 11 of the plate member 20 and the driving member 12, and a free range 13 is formed by this interval.

The needle 1 is placed between two plate-like members 20 and 20 that protrude from both knives 11 and 11 in opposite directions, and that the tips of these plate-like members are the same without any lateral deviation from each other. The two associated main hooks 3, 3 are respectively entrained by two opposingly protruding entraining elements 12, 12 which can be overlapped in position, in a corresponding receiving engagement.

In this case, when viewed in plan, the plate members 20 are arranged in a staggered manner with each knife being shifted by a half pitch of the attachment pitch.

This embodiment is different from the first embodiment in that the entraining member 12 is not provided directly on the knife 11 but on a plate-like member 20, and the plate-like member 20 It performs a direct action comparable to that of the knife of the embodiment.

That is, instead of the knife in the first embodiment, basically in this embodiment, the needle main body 1 does not make any contact with the plate member 20, and its tilting or Without bending, as shown in FIG. 12, the main hook 3 is brought into reception engagement by the driving member 12, the main hook is tilted about the pivot axis 5, and the lifting is released, or the driving member 12 of the main hook 3 is moved. The actions of moving away from the main hook in the lateral direction along the plate-like member 20 and restoring the main hook from the tilting movement are performed smoothly and reliably.

The major difference between this embodiment and the first embodiment is that the horizontal needle 14
The pushing adjustment control movement of the needle 1 by the knife 11.11
This is carried out in a direction along the plate member 20 intersecting (orthogonal to) the length direction, and the main hook 3 is moved from the entraining member 12 in the lateral direction and is retracted. The free range 13 of the knife 11 of the plate member 20
and the driving member 12.

Next, in the embodiment shown in FIGS. 13 to 15, the plate-like members 20 attached perpendicularly to the knives 11 are arranged at the same position with matching pitches for each knife when viewed in plan.

For this reason, although the plate-like members 20 protrude from adjacent knives facing each other in opposite directions, the protruding length is such that there is some spacing between the tips so that the tips do not come into contact with each other. It is said to belong to

Therefore, the two knives 11, 11 which belong to the two main hooks 3, 3 of the cylindrical needle 1 and are adapted to receive and engage with it and take it with them, extend in opposite directions between them in an oblique direction when viewed from above. Two adjacent plate members 20.20
Two driving members 1 protruding from opposite ends of the
There is some deviation from left to right (in the direction crossing the knife) between No. 2 and No. 12.

For this reason, in response to this deviation, the needle 1 shown in FIG. 3 is used, in which both main hooks 3, 3 are disposed with deviations on the left and right sides of the main needle body 2.

Other than this point, the structure and operation of this embodiment are basically the same as those of the third embodiment.
