Reference numeral 17 denotes a pair of lowering cams arranged inside each of the knitting cams 12, which can lower the pads of the knitting needles 3 introduced from the corresponding knitting cam 12 side and lock the shanks to the locking members. Hold in position temporarily.

Reference numeral 18 denotes a needle selection cam disposed inside the rolling down cam 17, which allows the pads of the knitting needles 3 at the rolling down position that have been rolled down by the corresponding rolling down cams 17 and are locked in the locking member to pass through as they are; The pad of the knitting needle 3 which has returned to the upper position without being locked is moved backward.

Due to the cam arrangement, between the front partition plate 10 and the needle selection cam 18, the pads of the knitting needles 3 selected forward are placed in the yarn feeding preparation position (as shown in FIG. 1, the tip of the hook is the sinker). A yarn feeding preparation passage A is formed which projects forward of the hook 2 and guides the hook to a position where the pile yarn can be supplied from the pile yarn opening described later.

Further, the knock-over cam surface 13 of the knitting cam 12 causes the bar of the knitting needle 3 in the yarn feeding preparation path A to be retracted to the knock-over position (a position where the hook is disposed slightly behind the sinker 2). A rear guide passage opening for knitting the large pile loop described later is formed. Furthermore, the forward cam surface 14 of the knitting cam 12 forms a front guide path C for forwardly guiding the pads of the knitting needles 3 in the yarn feeding preparation path A to knit a small pile loop described later. 19 in the diagram

As shown in FIGS. 2 and 4, it is possible to take a lower working position where it can engage with the pad of the knitting needle 3 and an upper non-working position where it cannot engage with the pad. In this case, the inner end of the knitting cam 12 and the outer end of the needle selection cam 18 abut against each other, so that the range of rotation thereof is limited. In order to arrange the switching cam 19 at each of the working and non-working positions, a pair of upper and lower circumferential grooves 23 and 24 are formed on the shaft 21.
The support base 22 is provided with balls 26 which press into the respective circumferential grooves 23 and 24 by the action of a spring 25, and a knob 27 for manual operation is fixed to the upper end of the shaft 21. In the figure, reference numeral 28 denotes an auxiliary gear ring on which the auxiliary needle bed 5 is mounted so as to be slidable left and right, and a knitting cam mechanism is arranged symmetrically on the back side thereof.

In the figure, reference numeral 40 denotes a loop removal gear ring dedicated to removing the knitted pile loops from the knitting needles, and is installed on the main needle bed 1 so that it can slide left and right and be detachable at any position. A rear introduction passage 41 that introduces the pads of the knitting needles 3 at the knitting preparation position a front side introduction passage 42 that introduces the pad of the knitting needle 3 led out to the flattening position Y, and an advancing cam 43 that advances the pad of the knitting needle 3 introduced from the rear side introduction passage 41 to the flattening position Y; Retraction cams 44 that retract the pads of the knitting needles 3 at the flat-out position Y to the knitting preparation position X are arranged symmetrically, and are always held by a spring at the left and right center front portions, as shown by solid lines. A guiding cam 45 is pivotally mounted to guide the pad of the knitting needle 3 at the flattened position Y to the retreating cam 44.

This embodiment is configured as described above. The pile section will be explained below, but first, we will explain the large pile loop formation, for example, starting from the formation in which all of each course is a large pile loop. First, the opening/closing cam 16 of the main gear chain 9 is placed at the position shown by the rear solid line, The switching cams 19 are respectively arranged at the lower operating positions, and the pile yarn T1 is placed at the pile yarn opening 37.
In other words, the ground threads T2 are inserted into the ground thread openings 38, respectively, and all the knitting needles 3 of the main needle bed 1 are introduced into the yarn feeding preparation path I by the needle selection cam 18. , the locking member is set to lock all of the reduction knitting needles 3 according to the needle selection information.

By sliding both gear rings 9 and 28 onto the active knitting needle section that has been knitted in advance, the knitting needles 3 of the main needle bed 1
is introduced from the knitting preparation position X, and then guided to the knitting preparation position The pile yarn T1 is supplied to the hook of the knitting needle 3, and the pile yarn T1 is drawn behind the sinker 2, thereby knitting a large pile loop LP. On the other hand, at the same time, the knitting needles 8 of the sub-needle bed 5 are guided to the knitting path indicated by the dashed line shown in FIG. As a result, a new plating loop W is knitted. Next, by sliding the loop removal gear ring 40 (either the left or right direction is fine), the pads of the knitting needles 3 on the main needle bed 1 are introduced from the rear introduction passage 41 as shown by the dashed line in FIG. During this time, the large pile loop LP that has been knitted is pulled out once and then knocked over.

With the above steps, the pile edition for the − course is completed.

Next, by folding and sliding both gear rings 9 and 28, the knitting needles 3 of the main needle bed 1 knit the large pile loop LP, and the knitting needles 8 of the sub needle bed 5 knit the plating loop, in exactly the same manner as described above. Organize W.

Subsequently, by sliding the loop removal gear ring 40, the knitted large pile loop LP is knocked over from the knitting needles 3.

Thereafter, the main gear ring 9 and the loop release gear ring 40 may be alternately slid in the same manner as described above, and as a result, the sixth
A pile knitted fabric having a structure as shown in the figure is obtained.

In addition, when knitting a patterned pile in which a certain part of each course is a large pile loop LP, the knitting needles 3 of the main needle bed 1 may be sorted into two groups, front and rear, by the needle selection cam 18,
As a result, the knitting needles 3 that are sorted forward and introduced into the yarn feeding preparation passage A knit a large pile loop LP in the same manner as described above, but the knitting needles 3 that are sorted backward knit a large pile loop LP because they are not supplied with pile yarn T1. There is no need to compose an LP.

In this case as well, after knitting the large pile loop LP, the loop removal gear ring 40 is slid to remove the large pile loop LP.
It is something that knocks over. Furthermore, as shown in FIG. 8, in order to knit and form a large pile loop LP for all of the courses at every - course, first move either the left or right opening/closing cam 16 to the forward position shown by the two-dot chain line. , the other opening/closing cam 16 may be placed at the rear position, and if both gear rings 9, 28 are thereby slid in the direction of the opening/closing cam 16 placed at the rear position, the same effect as described above can be achieved. If the large pile loop LP is knitted in the front position, and it is slid in the direction of the opening/closing cam 16 located at the front position, the large pile loop can be formed by simply passing through the main gear ring while the knitting needles 3 remain at the approximate knitting preparation position x. There is no LP knitting (during this time, the knitting needles 8 of the sub-needle bed 5 knit the plating loop w). In this case as well, the loop removing action by the loop removing gear ring 40 accompanies each knitting of the large pile loop LP. As a result, the 8th
A pile knitted fabric having a structure as shown in the figure is obtained. In this case, the large pile loops LP are knitted at every other course, but if one or both of the left and right opening/closing cams 16 are placed at the front position at every arbitrary course, the large pile loops LP can be knitted every other course. It is something. In the above, the loop removal gear ring 40 is used to knock over the large pile loop LP that has been knitted, but the main gear ring 9 can also be used to knock over the large pile loop LP without using this gear ring 40.

That is, for example, in order to perform knitting in which the entire course is a large pile loop LP, as shown in FIG. When the main gear ring 9 slides in one direction left and right, all the knitting needles 3 are selected forward by the needle selection cam 18, and when the main gear ring 9 slides in the other direction left and right, all the knitting needles 3 are selected. The cam 18 is used to sort the samples backwards.

As a result, when both gear rings 9 and 28 are slid in one direction left and right, a large pile loop LP is formed in the same manner as described above.
Further, when both the gear chains 9 and 28 are slid in the left and right directions, the knitting needles 3 that have knitted the large pile loop LP are advanced to the lug removal position by the opening/closing cam 16 and the lug removal cam surface 15, and the large pile loop LP is moved forward to the lug removal position. After the knitting needle 3 is pulled out, the knitting needle 3 is retreated to the knockover position by the front partition plate 10, the switching cam 19, the needle selection cam 18, and the knockover cam surface 13 of the knitting cam 12 on the opposite side, and the large pile loop LP is Knock over. Thereafter, it is only necessary to reciprocate both the gear rings 9, 28, and each reciprocation knits the - course of large pile loops LP and the two courses of plating loops W. As a result, the eighth A pile knitted fabric having a structure as shown in the figure is obtained.

The various formations of large pile loops have been explained above.
Below, we will explain the formation of small pile loops, starting with the formation in which all of the courses are water pile loops. First, the opening/closing cam 16 of the main gear link 9 is placed in the rear position, and the switching cam 19 is placed in the upper inactive position. Place them respectively, and
All the knitting needles 3 of the main needle bed 1 are introduced into the yarn feeding preparation path I on the front side by the needle selection cam 18.

By sliding both gear rings 9 and 28 into the active knitting needle section, all the knitting needles 3 of the main needle bed 1 are guided to the yarn feeding preparation passage A, and then the forward cam 14 of the knitting cam 12 on the opposite side is guided. The pile yarn T1 is introduced into the front guide path C, which is advanced forward, and here, the pile yarn T1 is supplied to the upper surface of the needle stem behind the opening latch of the knitting needle 3, and a small pile loop SP is knitted.

(The small pile loop SP is knitted by pulling the pile yarn T1 on the left and right sides of the needle stem of each knitting needle 3 by the hook of the knitting needle 8 of the sub-needle bed 5.) After this knitting, the knitting needles 3 are guided to the flattening position Y. Meanwhile, at the same time, the knitting needles 8 of the sub-needle bed 5 knit the plating loop W. Subsequently, the small pile loop SP is knocked over by sliding of the loop removal gear ring 40. Thereafter, it is only necessary to repeat the operation of alternately sliding the gear rings 9, 28 and the loop release gear ring 40, thereby obtaining a pile knitted fabric having a structure as shown in FIG. 7. be.

In addition, in the case of knitting a patterned pile in which a certain part of each course is a small pile loop SP, the knitting needles 3 on the main needle bed 1 may be sorted into two groups, front and rear, using the needle selection cam 18. Accordingly, the knitting needles 3 sorted forward knit the small pile loop SP in the same manner as described above, but the knitting needles 3 sorted backward knit the small pile loop SP since the pile yarn T1 is not supplied to the knitting needles 3 sorted backward. There is no.

In this case as well, the knockover of the small pile loop SP is performed by the loop removal gear ring 40. Furthermore, as shown in FIG. 9, in order to knit small pile loops SP for all of the courses at -course intervals, the opening/closing cam 1 on either the left or right side is required.
6 is placed in the front and the other opening/closing cam 16 is placed in the rear, and the small pile loop SP is formed only when both gear rings 9, 28 are slid in the direction of the opening/closing cam 16 placed in the rear position. It is intended to do so.

In this case as well, the knockover of the small pile loop SP is performed by the gear ring 40 that removes the loop. In this case, when knitting the small pile loop SP, by sorting the knitting needles 3 back and forth using the needle selection cam 18, a patterned pile is knitted in which a certain part of the course is made into a small pile loop SP. It is possible to do this. In addition, by switching the arrangement of both opening and closing cams 16, it is also possible to knit small pile loops SP at alternate courses as appropriate. Furthermore, as in the case of knitting the large pile loop LS, the knitted small pile loop SP can be knocked over by the main gear link 9 without using the loop removal gear link 40. be. That is, in this case, after the switching cam 19 is placed in the inactive position and the small pile loop SP is knitted as described above, when knitting the next course,
If the switching cam 19 is placed in the operating position and all the knitting needles 3 are sorted backwards by the needle selection cam 18, the sliding of both gear rings 9 and 28 will cause the small pile loop SP to be formed in the front course. Since the knitting needles 3 that have knitted are moved back from the flattening position Y to the knockover position, the small pile loop SP is knocked over.

In this way, a pile knitted fabric as shown in FIG. 9, for example, can be obtained. A second embodiment embodying the present invention will be described below with reference to FIGS. 10 and 11. Note that the same names and symbols as in the above embodiment are used for parts common to the above embodiment. 46 in the figure is the main needle bed 1
The main gear ring is mounted on the top so that it can slide left and right, and the following cams are arranged symmetrically on the bottom surface.

That is, 47 is a front diaphragm, 48 is a rear diaphragm, 49 is a lowering cam,
Reference numeral 50 denotes a needle selection cam, and 51 a movable cam 52 which can be switched between two positions, which guides or not guides the pad of the knitting needle 3 in the knockover position to the lowering cam 49; A knockover cam surface 53 is formed to form a backward guide passage opening for retracting the pad of the knitting needle 3 in the yarn feeding preparation passage A to the knockover position, and a front guide passage C is for conversely advancing the pad to the flattening position. A forward cam surface 54 and an outer retracting surface 55 are formed.

Reference numeral 56 denotes a knock-out cam, and an auxiliary knockover cam surface 57 is formed on the inside thereof. Reference numeral 58 denotes a movable forward cam pivotally connected to the rear end of the knockover cam 56, which guides the pad of the knitting needle 3 introduced from the outside of the gear ring at the knitting preparation position X to the flattening cam 56.

Furthermore, numeral 59 in the figure is a switching cam whose base end is pivotally connected to the inner end of the knitting cam 52, as shown in FIG.
The pads of the knitting needles 3 in the yarn feeding preparation passage A can be switched between a front position where the pads are introduced into the rear guide passage opening and a rear position where the pads are introduced into the front guide passage C.

On the other hand, the auxiliary gear ring 60 includes a knitting cam mechanism for knitting the plating loop w in the same manner as in the embodiment described above, that is, an upper partition plate 61, a lower partition plate 62, a knitting cam 63, and an auxiliary raising cam 6.
4 is provided.

In addition, the connecting plate 65 that connects both gear rings 46 and 60 has a
A pile thread opening 66 and a ground thread opening 67 are provided.

This embodiment is configured as described above.

Therefore, I will explain the pile version below, but first,
For example, when forming a large pile loop LP,
If all courses are to be large pile loops LP, move the left and right movable cams 51 of the main gear link 46 to the rear position in advance.
The left and right switching cams 59 are respectively arranged at forward positions, and all the knitting needles 3 of the main needle bed 1 are selected forward by the needle selection cam 50.

By sliding both the gear rings 46 and 60 into the active knitting needle section, the knitting needles 3 of the main needle bed 1 are first advanced to the lug removal position by the movable advance cam 58 and the lug removal cam 56, and are moved to the old large pile loop. After the LP is pulled out, it is retreated to the knockover position by the outer retreating surface 55 of the knitting cam 52 to knock over the old large pile loop LP, and then moved forward by the movable cam 51 and fed by the needle selection cam 50. After being introduced into the preparation path A, it is guided to the rear guide path opening by the switching cam 59, where it receives the pile yarn T1 and knits a large pile loop LP, and is thereafter guided directly to the knitting preparation position X. .

On the other hand, the knitting needles 8 of the sub-needle bed 5 knit a plating loop W. Thereafter, by folding and sliding both gear rings 46 and 60, the same action as described above is repeated, and as a result, a pile knitted fabric having a structure as shown in FIG. 6 can be obtained.

By sorting the knitting needles 3 back and forth by the needle selection cam 50, each of the above-mentioned courses is partially formed into a large pile loop L.
It can be a pattern pile organized by P.

Furthermore, if one of the left and right movable cams 51 of the main gear link 46 is placed at the front position and the other movable cam 51 is placed at the rear position, large pile loops LP can be formed at -course intervals, and in this case. , large pile loop LP for the entire course
If so, a pile knitted fabric with a structure as shown in FIG. 8 can be obtained, and if a part of the course is made into a large pile loop LP according to the needle selection pattern, a pile knitted fabric with a patterned structure can be obtained.

By appropriately switching and arranging both movable cams 51 to the front position, large pile loops LP can be knitted at arbitrary courses. Next, when knitting a small pile loop SP,
The switching cam 59 of the main gear ring 46 is placed at the rear position, and the knitting needles 3 are guided from the yarn feeding preparation path A to the front guide path C to knit the small pile loop SP. The small pile loop SP is knocked over by retreating to the knockover position using the auxiliary knockover cam surface 58 of the knitting needle 3. If the yarn is introduced into the yarn preparation path A or partially introduced into the yarn preparation path A, or in addition, the left and right movable cams 51 are placed at appropriate forward positions, various types of knitting similar to the knitting of the large pile loop LP can be performed. It can be carried out.

For example, if every course is made with small pile loops SP, a bi-le knitted fabric with a structure as shown in Fig. 7 will be obtained, and if every course is made with small pile loops SP in every other course, a bi-le knitted fabric with a structure as shown in Fig. 9 will be obtained. A pile knitted fabric is obtained respectively. As described in detail above, the present invention has two gear rings connected by a connecting plate having a ground thread opening and a pile thread opening! One gear ring is provided with a knitting cam mechanism for plating loop knitting, and the other gear ring for pile loop knitting is provided with a yarn feeding preparation path that guides the knitting needles to the yarn feeding preparation position, and a large pile knitting cam mechanism. A rear guide passage for knitting a loop, a front guide passage for knitting a small pile loop, and a switching cam for switching and introducing the knitting needles in the yarn feeding preparation passage into either of the guide passages. It is something.

Therefore, if the switching cam is placed in one switching position, a large pile loop can be knitted, and if it is placed in the other switching position, a small pile loop can be knitted. It is possible to easily switch to a pile loop formation or vice versa.
