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, these ring temples are used to prevent the fabric from shrinking by pricking both ends near the opening of the fabric with a needle, etc., and they not only damage the fabric, but also only damage the fabric near both ends of the fabric where the needles are inserted. However, when a dense woven fabric is woven, 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 the warp yarns, reduce warp breakage, and prevent temple damage and tearing.

Figure 1 is a plan view of a conventional full-width temple (Figure A).
and its aa' cross-sectional view (lower figure) is shown. In the figure,
1A is a supporting member, 2A is a holding member, and 3A is a long hole for mounting 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, the operability is not good,
In addition, in order to make the fabric gripping rod, which needs to be changed depending on the type of fabric, detachable from the supporting member and presser member, bolts and nuts must be attached so that the two members can slide. The mounting hole 3A into which the instrument 4A is inserted has to be a long hole. 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.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its object is to provide a full-width temple that can securely and uniformly grip a fabric over its entire width while improving its operability. It is said that

[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 in the longitudinal direction of either the support member or the presser member, When the support member and the presser member are integrated and attached to a loom to grip the fabric, the tension applied to 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 groove having a flat surface, and forming an engagement groove that engages with the engagement groove in the other longitudinal direction of the supporting member or the pressing member;
Its main feature is the full-width temple, which is characterized by

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

FIG. 2 is a perspective view of the support member and presser member of the full-width temple of the first embodiment. In the figure, 11 indicates a support member, and 12 indicates a presser member.

The support member 11 is fixed to the loom main body in the direction of its short side, and has an attachment part 1 that engages with the presser member 12.
1A, and a textile gripping part 11B on which a textile gripping rod (not shown) is rotatably disposed, and the attachment part 11A is provided with a restraining protrusion 11C on the interface with the textile gripping part 11B. The restraining protrusion 11C is inclined toward the fabric gripping portion 11B as shown in the figure. Further, the cross section of the fabric gripping portion 11B is approximately L-shaped, and has a rolling regulating protrusion 11D at the end.

The holding member 12 similarly includes an engaging portion 12A that engages with the support member 11 in the direction of its short side, and a rolling restriction portion 12B that restricts the amount of rolling movement of the fabric gripping rod. An occlusal ridge 12C that engages with the restraining ridge 11C is provided on the rolling restriction portion 12B side of the occlusal portion 12A.
A protrusion having approximately the same size as the restraining protrusion 11C of the support member 11 is provided so as to be inclined in a direction opposite to the rolling restriction portion 12B side. The rolling restriction portion 12B has a gently curved inner surface.

FIG. 3 shows a side view of a state in which the supporting member 11 and the pressing member 12 are engaged with each other and the fabric gripping rod 13 is held between the two members. As shown in the figure, the support member 11 and the presser member 12 engage with each other through their attachment portions 11A and engagement portions 12A. 13 is a textile gripping rod, which is a textile gripping part 11B.
and a gripping space 13A surrounded by the rolling restriction portion 12B.
It is said that it can roll freely inside. 14 is a gripping space 13
It is also a gap for guiding a textile (not shown) into A and allowing the textile wrapped around the textile gripping rod 13 to be taken out again from the gripping space 13A.

FIG. 4 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 15 indicates the woven fabric, and 15A and 15B indicate the warp yarns forming the fabric 15. 16 is a connector that connects the breast beam 17 and the full-width temple.

The fabric 15 is constructed by using a shuttle, needle, rapier, gripper, or a reed (not shown) for weft threads stretched by water or air as a carrier for inserting the weft threads between the warp threads 15A and 15B. Drive to 15C, then warp 1
The relative positional relationship between 5A and 15B is reversed, that is, the warp thread 15A is moved below the warp thread 15B, the weft thread is sandwiched between these two warp threads 15A and 15B, and then a new weft thread is inserted between the warp threads 15A and 15B. This can then be obtained by repeatedly performing the same operation. The woven fabric 15 is strongly pulled in the direction of the presto beam 17, and its opening 1
5C is balanced by being pulled by the warp yarns 15A and 15B in a direction substantially opposite to the above-mentioned tensile force. Therefore, due to these two tensile forces, a force is applied to the fabric gripping rod 13 such that it is pulled out from within the gripping space 13A through the gap 14, and this force causes the fabric gripping rod 13 to The fabric 1 is held between the support member 11, the fabric gripping rod 13, and the pressing member 12.
5 is gripped over its entire width.

Due to the two tensile forces acting on the fabric 15 described above, the full-width temple of this embodiment and the support member 1
A force indicated by an arrow in the figure is applied between 1 and the presser member 12. The support member 11 is the connecting tool 1
6, this force causes the presser member 12 to slide away from the support member 11 in the direction opposite to the cloth opening 15C. However, as shown in the figure, the restraining protrusion 11C provided on the support member 11 and the occlusal protrusion 1 provided on the pressing member 12
2C is provided to protrude in a direction perpendicular to the acting force shown in advance by this arrow, and is a restraining protrusion 11C.
The surface on the side of the cloth opening 15C (deterrent surface) and the occlusal ridge 12C
The cloth opening 15C side and the opposite surface (occlusal surface) are pressed together, and the presser member 12 is engaged with the support member 11.

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

First, the mutual relationship between the gripping space 13A formed by the support member 11 and the presser member 12 and the fabric gripping rod 13 is no different from that of a conventional full-width temple. Therefore, when the cloth opening 15C is struck with a reed, the tension of the warp yarns 15A and 15B becomes maximum. This is because the cloth opening moves in the direction of the breast beam 17. On the other hand, the tension acting on the fabric 15 at this moment becomes the lowest. However, at this time, the fabric 15 is strongly pulled in the direction of the presto beam 17, so the fabric gripping rod rotates smoothly with the gap 14 blocked, and the amount of fabric woven is transferred to the winding roller of the loom (not shown). Breast beam 1 due to tension
Move in the direction of 7. When the reed recedes from the weave, the fabric gripping rod is again strongly attracted to the gap 14 by the tension of the warp threads 15A and 15B. This force grips the fabric over its entire width.

Next, the operability in removing or attaching the fabric gripping rod 13 from the gripping space 13A, whose diameter and surface shape must be changed depending on the type of fabric, is improved. The support member 11 and the presser member 12 are attached using tension applied to the fabric 15 without using any attachment device. Therefore, when the fabric 15 is not attached to the full-width temple, such as when the fabric gripping rod 13 is attached or taken out, two members, the support member 11
The presser member 12 simply rests on the support member 11 due to its own weight, and the two members can be separated by simply pushing the presser member 12 lightly in the direction of the fabric opening 15C. 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, when attaching the two members again, the entire width can be attached by a simple operation of interlocking the restraining protrusion 11C and the occlusal protrusion 12C. Therefore, unlike the conventional method, the fabric 1
The grip of No. 5 is uniform over the entire width.

Furthermore, like the diameter of the fabric holding rod 13, the opening degree of the gap 14 of the full-width temple must be variable depending on the type of fabric 15, etc.; If several types of presser members are prepared in which the shape of the support member 12A is exactly the same and only the shape of the rolling restriction portion 12B is suitable for various types of fabrics 16, the support member 11 and the presser member 12 can be Attachment and detachment can be done with simple operations, which also greatly improves operability.

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. 5 are also equivalent.

In FIG. 5A, the support member 111 has almost the same shape as the first embodiment, and the presser member 121 has the occlusal projection 12C.
A recess 121 that engages with the restraining protrusion 111A instead of
A is provided. Taking this structure, the first
Since the occlusal surface between the two members is increased compared to the example, it is possible to achieve even stronger occlusion.

In addition, FIG. 5B shows the relationship between the two members described above reversed, and the holding member 122 has almost the same shape as the first embodiment, and the supporting member 112 has a recess 112A instead of the restraining protrusion 11C. It has been established. In this full-width temple, since the holding member 122 has a large volume, the occlusion due to its own weight increases, and the mounting force between the two members increases.

Figure 5C shows the occlusal part restraining protrusion 1 of the first embodiment.
13A, 113B and occlusal ridges 123A, 123
It has the double structure of B, and further strengthens the occlusal force between the two members. Incidentally, both the support member 113 and the presser member 123 are designed to interlock by providing protrusions, but one of them may have a concave structure as shown in FIGS. 5A and B. There is no problem in combining things as appropriate.

[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 engaging protrusion and the engaging groove engage with each other over the entire length of the full-width temple.

Therefore, it not only maintains the effect of a full-width temple similar to the conventional one, 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 possibility of any discrepancy in the relationship.

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.

Moreover, since both members engage using the tension of the fabric, when removing the fabric and replacing the fabric gripping rod that was gripping it inside, both members can be easily removed and the fabric gripping rod can be replaced. etc. work efficiency is greatly improved.
