Embodiment Construction

[0026] The present invention will be further described below in conjunction with embodiment.

[0027] see Figure 1 to Figure 8 , an excess weft insertion system for a rapier loom, comprising: weft racks 0-2, several weft feeders 0-3, weft yarn tensioners 0-4, weft yarn detectors 0-5, and several weft selection fingers 0-6 , weft scissors 0-7, weft sending sword 0-8, weft receiving sword 0-9, release plate 0-10; Weft yarn detectors 0-5, weft scissors 0-7, and release plates 0-10 are all installed on the loom frame 0-1. Weft yarn 4 is drawn out after being dynamically stored by weft feeder 0-3, and passed through the weft yarn tension respectively. Device 0-4→Weft yarn detector 0-5→Weft selection finger 0-6→The end is clamped by waste edge. The simple description of dynamic weft insertion is: Weft selection fingers 0-6 select one of weft selection fingers 0-6 under the control of the weft selection mechanism (not shown in the figure), so that it extends down to a specific pos...

Abstract

The invention relates to an excess weft insertion system for a rapier loom. The excess weft insertion system comprises a weft rack, a plurality of weft storage devices and weft tensioners, a weft detector, a plurality of weft selecting fingers, a pair of weft scissors, a weft sending rapier, a weft receiving rapier, and a releasing plate, wherein the weft storage devices and the weft tensioners are both arranged on the weft rack, and the weft detector, the weft scissors and the releasing plate are all arranged on a loom rack; wefts are led out from the weft storage devices, and respectively pass through the weft tensioners, the weft detector and the weft selecting finger, and the tail end is clamped by a scrap edge. An excess weft sending device is also arranged between the weft detector and the weft selecting fingers and comprises a swing mechanism, a pulley set mechanism and a yarn guide roller fixing mechanism. The wefts stored by the excess weft sending device are quickly released to locally form a high weft density region, and the design and production of a special weft stripe style fabric that the wefts completely shield warps in a weft strip region with a certain strip width and a distribution rule are realized.

Description

technical field [0001] The invention relates to a weft insertion system of a rapier loom, in particular to an excess weft insertion system of a rapier loom for excess weft insertion of weft yarns with better elasticity. Background technique [0002] Weft strips with a certain width and regular distribution, and the special weft style fabrics in which the weft yarns in the weft strip area completely cover the warp yarns have become the ideal fabrics in the minds of more and more fashion designers. In order to meet this demand, most fabric designers design fabrics with local fine counts and high weft density or partial weft weave. , have failed to design and produce the ideal fabrics in their minds that satisfy fashion designers. Contents of the invention [0003] The object of the present invention is to provide a rapier loom excess weft insertion system that can perform excess weft insertion of the weft yarn with the cooperation of a relatively high elastic weft yarn. Th...
