Air jet loom

Abstract

The invention relates to an air jet loom comprising a weft yarn feeding device, a warp yarn feeding device, an interweaving device and a weft yarn slitter edge cutting device. On one hand, weft yarnsare ensured to be interwoven under set tension, hence improving the weaving quality as well as reducing the yarn breakage probability, and meanwhile, a yarn clamp is arranged to prevent the situationthat a yarn end retracts into a spinneret opening when a yarn is accidentally broken, thereby facilitating joint treatment after the yarn is broken; and on the other hand, on the premise of ensuring that the woven fabric is smooth and the warp yarns may not sideslip, the weft yarns with slitter edges are blown straight through an air flow formed by a rolling unit, the levelness of the outer end part of the cut weft yarns is ensured, the quality of the woven fabric is improved, and the air jet loom is simple in structure, convenient to implement and low in cost.

Description

technical field [0001] The invention particularly relates to an air-jet loom. Background technique [0002] At present, an air-jet loom mainly includes a weft yarn feeding device, a warp yarn feeding device, an interweaving device, and a weft yarn waste edge cutting device, wherein the weft yarn waste edge cutting device mainly includes a yarn used to interweave the outer ends of the waste edge. Line cutting unit and waste edge collection unit after cutting. [0003] However, in practice, it has the following disadvantages: [0004] 1) In the process of weaving or cutting, if the weft yarn is over-tensioned or over-slack, it will not only affect the quality of the woven fabric, but also increase the probability of weft yarn breakage; [0005] 2) Once the yarn breakage occurs, the weft yarn may be retracted into the spinneret, so that the splicing process after the yarn breakage is very cumbersome; [0006] 3) The weft yarn at the end of the waste edge is easy to be entang...

AI Technical Summary

Problems solved by technology

[0004] 1) In the process of weaving or cutting, if the weft yarn is over-tensioned or over-slack, it will not only affect the quality of the woven fabric, but also increase the probability of weft yarn breakage;

[0005] 2) Once the yarn breakage occurs, the weft yarn may be retracted into the spinneret, so that the splicing process after the yarn breakage is very cumbersome;

[0006] 3) The weft yarn at the end of the waste edge is easy to be entangled. If it is not combed, it is difficult to ensure the flushness of the outer end of the weft yarn after cutting, which will affect the appearance of the fabric;

[0007] 4) The warp yarns are prone to slippage, causing a large number of defects on the surface of the produced fabrics, which directly affects the quality of the fabrics. At the same time, it is impossible to ensure that the weaving fabrics are cut in a relatively stable state. The length is difficult to meet the processing needs
