Problems solved by technology

[0003] At the same time, the weaving process is accompanied by the beating motion, which makes the warp yarn fluctuate greatly and the loom vibrates greatly, which intensifies the weft shrinkage of the cloth width and causes the cloth surface to loosen and warp loose. ) for staple warp yarns, there is a problem that the warp breakage rate remains high

Embodiment Construction

[0014] The full-width cloth support device of the rapier jacquard loom includes a single semicircular cover plate 1, a single semicircular support plate 2 and a single strip movably arranged between the cover plate 1 and the support plate 2. Screw rod 3, said screw rod 3 is formed with two continuous threads with the same pitch and opposite helical directions respectively inclined toward the rod end from the middle position of the rod, and the fabric inlet and outlet 4 is formed between the front end 11 of the cover plate and the front end 21 of the support plate.

[0015] The fabric 7 is continuously interwoven with the upper warp yarn 51 and the lower warp yarn 52. With the weaving movement of the rapier jacquard loom, the fabric formed at the weaving fell 6 continues to move into the front end 21 of the support plate, and then wraps the screw in the moving state. 3 and move out the front end 11 of the cover plate to be rolled away from the full-width cloth support device of ...

Abstract

The invention discloses a full-breadth cloth supporting device of a rapier jacquard loom and belongs to the technical field of accessories of the rapier jacquard loom. The full-breadth cloth supporting device comprises a mono-block semicircular cover plate, a mono-block semicircular cloth supporting plate and a single screw movably arranged between the cover plate and the cloth supporting plate, wherein the screw is provided with two continuous threads formed at the middle position of the screw, respectively inclining towards the screw end, identical in screw pitch and opposite n spiral direction, and a fabric inlet-outlet is formed between the front end of the cover plate and the front end of the cloth supporting plate. The screw is round, and the fabric wrapping the screw position is an open roundness. After the technical scheme is adopted, cloth tightly wraps the screw, a holding wrap angle is large, the lifting force of upper-layer warp yarns on a full-breadth fabric and downward pressing force of lower-layer warp yarns on the full-breadth fabric in open motion can be decreased, tension borne by warp yarn tension can be decreased during beating-up motion, continuous evenness and consistency of the tension of the full-breadth fabric is ensured, fabric-breadth weft contractility is small, and warp yarn breakage rate is low.

Description

【Technical field】 [0001] The invention relates to a full-width cloth support device of a rapier jacquard loom, and belongs to the technical field of rapier jacquard loom accessories. 【Background technique】 [0002] At present, the manufacture of rapier jacquard looms is mainly assembled from three sets of equipment: general rapier looms, dressers and jacquard machines. Among them, the cloth support structure of general rapier looms is not suitable for For professional jacquard weaving, it usually installs left and right fabric support devices on both sides of the rapier loom, which only play a limited role in supporting the left and right sides of the fabric. The formed fabric is translated across the bottom of the temples and barbed shafts. In the weaving process of jacquard fabrics, the weaving process requires a maximum warp lifting ratio of 90% at the opening. The upper warp yarns formed by the opening have a great lifting force on the entire fabric. , the direction of...
