Waste selvage material saving method for rapier loom

Abstract

The invention relates to the technical field of textile machinery, in particular to a waste selvage material saving method for a rapier loom. The rapier loom is provided with an energy-saving device which is matched with weft shuttles, the energy-saving device comprises multiple weft clamping mechanisms corresponding to the weft shuttles, the energy-saving device further comprises a pair of weft scissors. According to the waste selvage material saving method for the rapier loom, the problem that due to the fact that waste selvage warp at the left side and the right side is removed, other weft which does not work temporarily cannot be clamped is solved, energy conservation is achieved, and meanwhile defective cloth is not produced.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a method for saving waste edge of a rapier loom. Background technique [0002] The rapier loom weaves the weft and warp together through the weft feeding sword and the weft receiving sword. In the process of weaving, in order to make the weft thread have sufficient tension when beating up, and to prevent defective fabrics due to the elastic retraction of the weft thread, the right warp line is often set on the right side of the cloth body, and the left warp line is set on the left side of the cloth body. Generally 12-16, more even 30, play the role of clamping the weft thread at this place, and the left warp side thread can clamp multiple weft threads when weaving multi-weft thread cloth. The two ends of the weft are clamped by the warp edge, and waste edges of a certain size are produced at both ends of the cloth body, resulting in a large amount of waste of warp and ...

Problems solved by technology

This method can save materials, but at the same time, there are unsolvable shortcomings: when there are more than two wefts, the inhaled wefts will be entangled and knotted under the action of the air vortex. Together, if the weft feeding mechanism sends one of the weft threads into the weaving area at this time, it will bring out the other one or several weft threads at the same time, resulting in a malfunction and resulting in defective cloth

This non-waste side yarn device is installed together with the rapier loom during use, and the original waste side warp yarn at the waste side part of the fabric on both sides is replaced by the warp yarn substitute thread, and recycled, avoiding to a certain extent The waste of warp yarn can be used for multi-weft weaving, which reduces the production cost, but because it uses warp yarn substitute thread to replace the waste edge warp yarn, it needs complicated spinning and separating mechanism, and it is not very convenient to install and use
