Problems solved by technology

[0003] In the existing technology, the warp yarns of ordinary rapier looms are completely supplied by only one to two weaving beams. During the weaving process, the yarns often rub against each other, which is easy to cause mutual extrusion, which is not conducive to maintaining the flat yarn after the widening treatment. cross-sectional shape

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figures 1 to 2 , a loom warp let-off device suitable for weaving non-bending fabrics, comprising a warp supply device 2, the warp supply device is composed of a number of single yarn shafts 7 with the same specifications and independent of each other, each single yarn shaft 7 Winding a single bundle of warp yarns 3, the single yarn shafts 7 are arranged in close proximity to each other and parallel to each other and pass through the same support shaft to be fixed on the loom base 1, which together constitute a warp yarn supply device passing through the same heald frame on the non-bending fabric weaving system.

[0021] The loom warp let-off device suitable for non-bending fabric weaving also includes a warp tension control device matched with the warp supply device 2, and the warp tension control device includes a circular tension weigh...

Abstract

A warp-feeding device applicable to no-bending fabric weaving is characterized by comprising a warp supply device (2), wherein the warp supply device is composed of a plurality of single-yarn shafts (7) which are consistent in specification and independent from each other, and a single warp strand (3) twines one single-yarn shaft (7). The single-yarn shafts (7) are tightly close to one another, arranged in parallel, penetrate through the same supporting shaft and fixed on a weaving machine base (1) to form the warp supply device which penetrates through the same heald frame of a no-bending fabric weaving system. According to the warp-feeding device applicable to no-bending fabric weaving, independent warp-delivery single-yarn shafts are applied, mutual frication and squeezing among warp can be effectively avoided, and therefore the warp-feeding device applicable to no-bending fabric weaving is beneficial to keeping a flat sectional shape of broaden yarn. Moreover, a tension heavy punch which 'can slip' is matched with the warp supply device and forms a warp tension control device can adjust the single-yarn state immediately, enables the tension of piece yarn to be even, reduces wear and broken yarn, and improves the weaving efficiency and the quality of fabric.

Description

Technical field [0001] The invention belongs to the field of rapier looms, and relates to a loom warp let-off device suitable for weaving non-bending fabrics, especially suitable for the weaving process of non-bending fabrics using stretched carbon fiber tows as raw materials. This let-off method innovatively controls the warp let-off and the tension difference between warp yarns during the weaving process, and improves the weaving quality of the loom while maintaining the cross-sectional shape. Background technique [0002] The rapier loom is mainly composed of frame, main transmission system, shedding mechanism, weft insertion mechanism, weft beating mechanism, take-up mechanism, weft yarn supply mechanism, selvedge mechanism, automatic weft-seeking mechanism, weft selection mechanism, lubrication system and control system and so on. [0003] In the existing technology, the warp yarns of ordinary rapier looms are completely supplied by only one or two weaving beams. Durin...
