Description

Detailed Description of the Invention [Technical Field] The present invention relates to a loom that alternately crosses warp threads and weft threads, and strikes the weft threads with reeds to form a woven fabric. Regarding the temple.

[Prior Art] Conventionally, ring temples, star temples, roller temples, etc. have been used to prevent weaving shrinkage of textiles that occurs when the weft threads of the textile are driven through reeds in a loom.

In principle, ring temples are used to prevent the fabric from shrinking by pricking both ends near the opening of the fabric with a needle, etc., which not only damages the fabric, but also causes shrinkage only in the very vicinity of the fabric where the needle etc. is inserted. When weaving a dense woven fabric without being able to suppress this, excessive tension is applied to the woven fabric, causing so-called temple flaws and temple tears.

Therefore, by gripping the entire width of the fabric near the opening, it is possible to reasonably suppress weaving shrinkage, and to stabilize the opening by suppressing the movement of the opening that occurs when weaving particularly dense fabrics. As a result, full-width temples have come into wide use because they can minimize sudden tension changes in warp threads, reduce warp thread breakage, and prevent temple damage and tearing.

Figure 1 is a plan view of a conventional full-width temple (Figure A).
and aa′ cross-sectional view (lower figure) are shown. In the figure, 1
A is a support member, 2A is a presser member, and 3A is an elongated mounting hole into which a mounting device 4A such as a bolt and a nut used to mount both members is inserted. As described above, these conventional full-width temples require other mounting devices 4A such as bolts and nuts in order to mount the support member 1A and presser member 2A that grip the fabric wrapped around a fabric gripping rod (not shown). There is. For this reason, in order to make the fabric gripping rod, which does not have good operability and needs to be changed depending on the type of fabric, detachable from the supporting member and the presser member, it is necessary to make these two members slidable. Therefore, the mounting holes 3A into which the mounting tools 4A such as bolts and nuts are inserted have to be elongated holes. Therefore, the relative positioning of the support member 1A and the presser member 2A is shifted in the long diameter direction of the elongated hole 3A, and the force for gripping the opening of the fabric is not uniform over the entire width of the fabric, making it difficult to finish the fabric. There was a possibility that this would occur.

Furthermore, the degree of opening of the gap 5A of the full-width temple for inserting the fabric held by the full-width temple is as follows:
It is necessary to adjust it appropriately depending on the type of fabric to be gripped. The opening degree of the full-width temple is narrow enough to allow insertion of the fabric, which is sufficient to achieve the purpose of grasping the fabric. If this gap 5A is opened more than the purpose of gripping the fabric, not only will the gripping force be reduced, but also foreign matter will more frequently jump into the gap 5A, causing weaving defects due to the foreign matter. It becomes. Textile factories use various types of yarn as materials, so there are many floating objects, so-called fluff, floating in the air within the factory. is necessary. In such a case, for conventional full-width temples, we prepare various holding members 2A that can change the opening degree of the gap 5A when attached to the same support member 1A, and each time the opening degree is changed, A method is adopted in which the device 4A is removed and the presser member 2A is replaced. Therefore, the number of pressing members 2A corresponding to the types of textiles is required,
It also has some disadvantages, such as high costs and poor storage efficiency.

[Object of the Invention] The present invention was made in view of the above-mentioned problems, and has improvements in operability, such as making it possible to securely and uniformly grip fabrics over the entire width, and using one full-width temple for all fabrics. The aim is to provide a full-width temple in which improvements can be achieved.

[Structure of the Invention] The structure of the present invention for achieving the above object includes an elongated support member, an elongated fabric gripping rod that is rotatably disposed on the support member, and a long fabric gripping rod that is rotatably disposed on the support member. In a full-width temple that grips the fabric over its entire width in the vicinity of the cloth opening, the temple is composed of a long presser member that regulates the amount of rolling movement together with the support member, and the support member is attached in the longitudinal direction of one of the support member or the presser member. When the member and the presser member are integrated and attached to a loom to grip the fabric, a tension force acting on the fabric causes a separation force that is approximately perpendicular to the direction of the separation force that acts between the support member and the presser member. forming an engagement protrusion having a surface, the width being wider than the protruding thickness of the engagement protrusion in the other longitudinal direction of the supporting member or the pressing member;
The gist thereof is a full-width temple characterized by forming a loose fitting groove into which the engaging protrusion is loosely fitted with a predetermined gap.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIGS. 2 and 3 are perspective views of the support member and presser member of the full-width temple of the first embodiment, and a side view of the two members in a state in which they are attached. In the figure, 1 indicates a support member, and 2 indicates a presser member.

The support member 1 is fixed to the loom main body in the direction of its short side, and has an attachment part 11 that engages with the presser member 2.
and a textile gripping rod 12 on which a textile gripping rod (not shown) is disposed in a freely rolling manner. The upper surface of the attachment part 11 is made up of a restraining rotation protrusion 13 that projects from the interface with the fabric gripping part 12 and slopes toward the fabric gripping part 12, and a flat occlusal support surface 14, and the bottom surface is provided with a connecting tool to be described later. It is provided with a groove 15 having an L-shaped cross section for engagement. As shown in the side view of FIG. 3, the inhibiting rotation protrusion 13 has an end edge 131 having a semi-cylindrical shape with a substantially semi-circular cross section. The fabric gripping part 12 bent into a V-shaped cross section rotatably holds a fabric gripping rod (not shown) in a groove formed inside the fabric gripping part 12 .

Similarly, the holding member 2 is attached to the supporting member 1 in the direction of its short side.
It is comprised of an interlocking part 21 that engages with the fabric gripping rod, and a rolling restriction part 22 that restricts the amount of rolling movement of the fabric gripping rod. The occlusal part 21 has a rolling restriction part 22 as shown in the figure.
The occlusal rotation protrusion 23 is placed near the boundary between the occlusal part 21
It is slanted and protrudes from the center side. The angle of inclination of the occlusal rotation protrusion 23 is almost the same as the angle of inclination of the inhibition rotation protrusion 13, as shown in the mounting side view of FIG. 3, and its protrusion is smaller than that of the inhibition rotation protrusion 13. be done. Then, the occlusal rotation protrusion 2 of the occlusal part 21
The side portion 231 of No. 3 is the end edge portion 13 of the restraining rotation protrusion 13
In order to enable crimping over a wide area such as 1, the edge portion 13
1 and the semicircular cross section are formed in a semicylindrical shape with the same radius. Further, the inclined surface 24 has an opening larger than the thickness of the deterrent rotation protrusion 13 relative to the occlusal rotation protrusion 23 in order to rotatably fit the inhibition rotation protrusion 13 to the side portion 231. It is provided.

Furthermore, the inclined surface 24 and the surface of the occlusal portion 21 connected thereto are connected to the central side surface of the attachment portion 11 of the restraining rotation protrusion 13 of the attachment portion 11 and the attachment portion 11 connected thereto.
is formed in the same shape as the surface of
The two members can be brought into close contact as shown in Figure A. Since it is formed as described above, two members,
As shown in FIG. 3B, the support member 1 and the presser member 2 engage with each other via the end edge 131 of the inhibiting rotation protrusion 13, the occlusal rotation protrusion 22, and the inclined surface 23, as shown by the arrow. It can be rotated freely. In addition, the rolling regulation part 2
2 is gently curved toward the occlusal rotation protrusion 23 and forms a gripping space 30 together with the fabric gripping rod 12 of the support member 1 .

FIG. 4 shows a side view of these two members, the support member 1 and the presser member 2, being engaged and the fabric gripping rod 40 being placed in the gripping space 30. Figure A is
Figure B shows the fabric S gripping an object that is thick and difficult to bend, and Figure B shows the fabric S gripping an object that is thin and easily bendable.

As shown in Figure A, when the fabric S is of a type that is difficult to bend, the fabric S gripped by the gripping space 30 and the fabric gripping rod 40 rotatably disposed therein will move in the direction of the arrow. It needs to be bent relatively gently in order to move smoothly and to be grasped. Therefore, the gap between the full-width temples is set wide to prevent the fabric S from being bent more than necessary.

However, when the fabric S is thin and easily bent, it is not possible to provide sufficient gripping force to the fabric S with the full-width temple setting as shown in Figure A. Therefore, as shown in figure B, the gap 50 is narrowed and the fabric S
By sufficiently bending the material, the gripping force is increased, and the gap 50 is kept to the minimum necessary to prevent fluff from flying in. In addition, in FIG. B, X is a trapezoidal spacer arranged on the occlusal support surface 14 of the support member 1 to regulate and adjust the amount of rotation of the presser member 2.

FIG. 5 is a schematic diagram showing a state in which the full-width temple of this embodiment configured as described above is mounted on a loom. In the figure, the two-dot chain line S indicates the woven fabric, and SA and SB indicate the warp threads forming the fabric S. 60 is a connector that connects the breast beam 70 and the full-width temple.

The fabric S is made by using a reed (not shown) to stretch the weft (not shown) by a shuttle, needle, rapier, gripper, water, air, etc. used as a carrier between the warp yarns SA and SB.
After that, the relative positional relationship of the warp threads SA and SB is reversed, that is, the warp thread SA is moved below the warp thread SB, the weft thread is sandwiched between these two warp threads SA and SB, and then the new weft thread is inserted into the warp thread This can be obtained by repeating the same operation between SA and SB. The woven fabric S is strongly pulled in the direction of the breast beam 70, and its opening
SC is balanced by being pulled in a direction substantially opposite to the above-mentioned tensile force by the warp threads SA and SB. Therefore,
These two tensile forces act on the fabric gripping rod 40 to pull it out from within the gripping space 30 through the gap 50, and this force causes the fabric gripping rod 40, the support member 1, The fabric S is held between the fabric gripping rod 40 and the pressing member 2 over its entire width.

Due to the two tensile forces acting on the fabric S described above, the forces indicated by the arrows in the figure act between the full-width temple of this embodiment, the support member 1, and the presser member 2. Since the support member 1 is fixed by the connector 60, this force causes the presser member 2 to slide away from the support member 1 in the direction opposite to the cloth opening SC. However, as shown,
The inhibiting rotation protrusion 13 provided on the support member 1 and the occlusal rotation protrusion 22 provided on the presser member 2 are provided in advance to protrude in a direction perpendicular to the acting force indicated by this arrow. , and the end edge 131 of the inhibiting rotation protrusion 13 is circular, and the side part 231 of the occlusal rotation protrusion 23 is circular.
Since they are circular with the same diameter, the support member 1 and the presser member 2 have a wide crimping area and engage with each other.

Furthermore, although the figure shows an example of the use of a full-width temple corresponding to a case where the fabric S is relatively thin, the full-width temple of this embodiment can be used depending on the presence or absence of a spacer Gap part 5
The opening degree of 0 can be arbitrarily varied. In either of these usage modes, the edge portion 131 has a semicylindrical surface shape with a substantially semicircular cross section;
Since the cross section of the side portion 231 of the occlusal rotation protrusion 23 that engages with the occlusal rotation projection 31 also has a substantially circular semi-cylindrical surface shape with the same diameter,
The support member 1 and the presser member 2 are rotatable and can maintain an occlusal state with a wide crimp surface.

The full-width temple of this embodiment constructed in this manner has the following effects.

First, the mutual relationship between the gripping space 30 formed by the support member 1 and the presser member 2 and the fabric gripping rod 40 is no different from that of a conventional full-width temple. Therefore, when the cloth opening SC is hit with a reed, the tension of the warp yarns SA and SB becomes maximum. This is because the cloth opening moves in the direction of the breast beam 70. On the other hand, the tension acting on the fabric S at this moment becomes the lowest. However, at this time, the fabric S has a breast beam of 70
Since the fabric gripping rod is strongly pulled in the direction of , the fabric gripping rod rotates smoothly while keeping the gap 50 closed, and the finished fabric moves in the direction of the breast beam 70 due to the tension of the winding roller of the loom (not shown). . When the reed recedes from the weave, the warp threads SA and SB
The fabric gripping rod is again strongly attracted to the gap 50 due to the tension. This force grips the fabric over its entire width.

Next, the operability in taking out or attaching the fabric gripping rod 40 from the gripping space 30, whose diameter and surface shape must be changed depending on the type of fabric, is improved. The support member 1 and the presser member 2 can be attached without using any attachment equipment.
This is done by utilizing the tension applied to the fabric S.
Therefore, when the fabric gripping rod 40 is attached or taken out, two members, the support member 1 and the presser member 2 are used, when the fabric S is not attached to the main full-width temple.
means that the presser member 2 simply rests on the support member 1 due to its own weight, and the presser member 2 is
The two members can be separated by simply pushing lightly in the direction of . In addition, even if both ends of the full-width temple are attached using attachment devices such as bolts to enable weaving during weaving, the two ends must be used to separate these two members. Only the attachment device is removed. Moreover, 2 again
When attaching two members, the entire width can be attached by a simple operation of interlocking the restraining rotation protrusion 13 and the occlusal rotation protrusion 23. Therefore, there is no intervening cause of misalignment between the two members caused by the elongated mounting holes as in the conventional case, and the grip of the fabric S becomes uniform over the entire width.

Furthermore, the diameter of the fabric gripping rod 40 and the opening degree of the gap 50 of the full-width temple must be made variable depending on the type of fabric S, etc. In such a case, the support member 1 and the presser member 2 are rotatably interlocked, so the opening degree of the gap 50 can be freely adjusted depending on the presence or absence of the spacer X and its shape. There is no need to prepare in advance,
Cost reduction and improved operability can be achieved.

Although the first embodiment has been described in detail above, the full-width temple according to the present invention is not limited to the above-mentioned structure, and the various shapes illustrated in FIG. 6 are also equivalent.

In FIG. 6A, the support member 101 has almost the same shape as the first embodiment, and the presser member 102 has the occlusal rotation protrusion 1.
The degree of protrusion of 22 is made the same as that of the inhibiting rotation protrusion 113. Therefore, the presser member 102 is rotated with respect to the support member 101 around the side portion A of the restraining rotation protrusion 113 in the weave direction. With this structure, the occlusal surface of the two protrusions increases depending on the state of use compared to the first embodiment, so it becomes possible to occluse even more strongly.

In addition, FIG. 6B shows a structure in which the support member 201 and the presser member 202 have a simple shape, but can freely rotate around the side part A of the inhibiting rotation protrusion 213. Not only does it have the same effect as the above, but it also aims to reduce manufacturing costs.

[Effects of the Invention] As explained based on various embodiments, the full-width temple of the present invention has a support member and a presser member formed as a pair by tension acting on the fabric gripped by the full-width temple. The engagement protrusion and the loose fitting groove engage in the longitudinal direction of the full-width temple,
Moreover, the holding member is rotatable about the engagement protrusion as a fulcrum by a predetermined gap formed between the engagement protrusion and the loose fitting groove.

Therefore, it not only maintains the effect of the full-width temple as in the past, but also eliminates the need for any locking members such as bolts or nuts when assembling the support member and presser member. There is no occurrence of any deviation in the positional relationship in the direction.

That is, the workability during installation on a loom is improved, and it becomes possible to evenly grip the weaving edge of the fabric over its entire width, which greatly contributes to improving the quality of the fabric.

Furthermore, since the two members engage using the tension of the fabric, the engagement between the two members can be easily released by removing the fabric. Therefore, the work efficiency for replacing the fabric gripping rod held inside, cleaning the fluff and glue that has flown into the inside, etc. is greatly improved.

Furthermore, it is possible to rotate the presser member and use it in an optimal state according to the flexibility of the fabric, and there is no need to prepare presser members of various shapes corresponding to the flexibility of the touch object. As a result, effects such as improvement in quality by preventing fabric defects due to fluff, reduction in costs by simplifying equipment, and improvement in production efficiency are achieved.
