Description

470794 B7 V. Description of the invention (!) [Technical field to which the invention belongs] The present invention relates to a weaving support device for a loom equipped with a temple device that reduces the shrinkage of the weaving fabric. [Known technology] & An upper-type side support device for a loom, which is arranged on two sides of the weave. One side support is formed by a plurality of links with a large number of needles, and the cloth is tightened from the upper direction. Each end of the woven fabric (each end of the cloth) is stretched along the direction of the web as the woven fabric advances. The side building is arranged on the end of the woven fabric near the weaving mouth 'so that the shrinkage of the woven fabric is suppressed near the weaving mouth. A loom having such a side support device is equipped with a weaving support device which supports the weaving under the weaving force against the pressing force from the weaving fabric. The weaving support device is to prevent the weaving mouth from descending with the opening movement of the warp thread, so it should be set as close to the weaving mouth as possible without impeding the beating movement. In this kind of woven fabric supporting device, a pair of cloth end guides (cloth guide members) in the cloth width direction receive the cloth width direction ends # of the cloth, so that the cloth center guide ( Guide bar) Those who accept the center of the web width direction (Japanese Patent Application Laid-Open No. 9-U250). The cloth end guide and the cloth center guide are connected to the end face in the cloth width direction. When changing the woven web, the center guide of the cloth is replaced with a guide having a size corresponding to the length of the new woven web. As for another kind of weaving support device, the left and right pair of cloth guides (¾ plates) are connected to receive the weaving cloth. When the weaving width is changed, the overlap amount of the two cloth guides is changed (Japanese Unexamined Patent Application No. Hei 4- Publication No. 202833 (苐 4). However, the former device must not only prepare multiple cloth guides with different lengths and dimensions, but also repair the corners of the parallel ends of each guide, and apply the Chinese National Standard (CNS) to each paper size. A4 specification (210 X 297 mm 1 311776 470794 2 2 A7 V. Description of the invention (2) Guides are used to prevent the occurrence of bruising caused by parallel joints plus χ. If this processing is performed, weaving will enter the guides. Between the end faces, small cloth weaves will still occur.: In the latter device, the cloth ends of the side building cannot be supported because the cloth ends of the cloth guides are not extended. Also, for example, the left and right guides extend To the end of the cloth, because the distance between the weaving mouth and the cloth guide varies with the left and right guides, the fabric is supported on the cloth end of the cloth guide with a large distance from the weave. Damage. The reason for the upper warp damage caused by the jet fluid is as follows. In fabrics with a large difference in the number of upper and lower warp threads, the tension difference between the upper and lower warp threads becomes larger, and the woven mouth of the warp threads moves up and down with the opening movement. At this time Supported on the cloth part of the cloth guide far from the weave The amount of mouth drop will be greater than the amount of cloth mouth drop supported on the cloth part of the cloth guide near the mouth. &Amp; On the other hand, the warp opening state when the jetting fluid for weft insertion passes through becomes the weft supply side ( The yarn feeding side) end is in the middle of opening, the central part is in the maximum opening, and the weft arrival side (anti-feeding side) is in the closing way, so when the projectile fluid passes, _ should be the opening amount of each part of the cloth end Because it is in the middle of opening or closing, it is very small. As a result, in the latter device, the jet fluid easily conflicts with the warp above the end of the cloth supported by the cloth guide far from the weaving opening, so it will damage the upper warp. At the same time, the jet fluid is scattered, reducing the flying speed of the weft thread and causing further damage to the warp threads. [Problems to be Solved by the Invention] Therefore, in the weaving support device of the weaving machine with a side support device, __ ^ 望It is possible to change without changing the cloth guide member.

Invention Explanation (3) As the opening movement of the warp threads decreases, the jet fluid causes damage to the warp threads. [Solution, function and effect of the invention] The woven fabric supporting device of the present invention is used for a loom having a side stay arranged on the upper side of one end of the woven fabric and a side stay arranged on the upper side of the other end. This kind of woven fabric supporting device includes: a cloth end guide, which is a pair of cloth end guides spaced along the width direction of the cloth, and each has a cloth provided with a guide portion that abuts an upper edge below the one end portion of the cloth An end guide, and a cloth end member provided with a guide having an upper end edge abutting the lower end of the cloth of the other end of the woven fabric; and a cloth central guide, which is a cloth central guide that is set on the two cloth end guides A guide portion having an upper end edge abutting the center lower surface of the woven fabric is provided. Each cloth end guide extends from the cloth width direction between the side support and the weaving mouth so that the outer end portion of the side support extends to the center of the fabric relative to the inner end. The guide portion of the central guide governs the cloth width direction. Guidance of each end portion abutting the cloth end guide = two opposite sides m at least-the cloth end guide and the central cloth guide of the month IJ are combined to be relatively movable in the cloth width direction. When changing the cloth weaving, the cloth end guide and the cloth center guide are moved relative to each other in the cloth width direction, and the repeat amount of the cloth end guide and the cloth center guide is repeated. Therefore, it is necessary to have a plurality of cloth guide members having a length and size that vary with the width of the cloth. Each end of the guide portion of the cloth center guide is repeated to the guide portion of the cloth end guide. The guide portion of the cloth end guide is not aligned with the cloth guide. And [therefore, the full width of the fabric is the cloth end guide-installed K --- order --------- thread (please read the precautions on the back before filling this page) 3 311776 470794 Cloth A7 invention description (4, at least one of the guides of the central guide is supported, so there will be no cloth defects caused by the woven fabric entering between the end faces of the two guides. The guides of the two cloth end guides It is the guide part of the center guide of the cloth; it is located on the weaving side. Therefore, the following effects are further produced. Because the ends of the two ends of the cloth direction corresponding to the warp threads do not fall to the center of the cloth direction Below the woven mouth of the warp thread, when the jetting fluid for weft insertion passes through, even if the opening amount corresponding to the warp thread is not sufficient, there will be no jet fluid contacting the upper warp thread, and fluffing on the upper warp thread will be caused by the jet fluid. The trouble of warp damage. In contrast, at the center of the fabric direction, when the mouth shoots the body through, the opening of the warp is large, so even if weaving The jetted fluid will not touch the warp threads below the cloth opening at the end of the cloth. Therefore, the warp damage caused by the jetted fluid will not occur in the entire woven fabric. The aforementioned cloth central guide can also be formed by a single member. In this case, compared to the case where the cloth central guide supporting the cloth central portion is divided into two or more members and connected, there is no cloth fatigue caused by the connection. Moreover, the cloth mouth side of the cloth central guide portion is relatively opposite On the anti-knitting side of the guide of the cloth end guide, make the body at the same distance from the knitting mouth and not in the direction of the anti-knitting. Therefore, it abuts and supports the guide of the central guide of the cloth. The central part of the woven fabric can also minimize the decline of the woven mouth with the movement of the opening. The central guide of the woven fabric can be provided with: _ pairs of anti-woven mouth side along the width direction of the fabric # ^ 偁 偁 pieces, s interval—the opposite weaving side guide member has a guide bow at the end of the fabric in the direction of the web, which repeats with the opposite end of the weaving side corresponding to the two ends of the cloth end guide ; And woven mouth side guide hibiscus ^ ^ / two opposite woven mouth side guide members of the woven mouth side guide H's Zhang scale adaptor '4 31177 丨 * ^ i ------ Order --------- ridge' (Please read the precautions on the back before filling out this page} Consumption of Intellectual Property Workers of the Ministry of Economic Affairs Printed by the association A7 A7 Member of the Bureau of Intellectual Property of the Ministry of Economic Affairs X Printed by the consumer cooperatives The paper size is applicable to the Chinese National Standard (CNS) A4 specification (21 × x 297 mm 5 V. Description of the invention (5) ', other directions ^ Each end portion abuts and repeats the weave-side guide portion of the guide portion of the reverse weave-side guide member. In this case, the weave-side guide member of the center guide of the cloth is also the cloth-end guide. It is also close to the weaving mouth, so even at the center of the weaving fabric, it can prevent the weaving mouth from falling with the opening movement, and the weaving cloth will not enter between the end faces of the weaving mouth side guide member and the reverse weaving mouth side guide member. Therefore, the cloth defects caused by it will not occur. The cloth piece and the cloth central guide ΐ are provided with a first plate-like portion having a guide portion abutting the upper end edge of the lower face of the woven cloth, and the lower edge of the lower plate 邛 is connected in the direction of the anti-weaving mouth.
