Device and method for controlling leno fabric warp on a loom

Abstract

The invention discloses a device and method for controlling the warp of leno fabric on a loom, and belongs to the technical field of weaving equipment in the textile industry. The device comprises a plurality of heald frames, a bracket, a first heddle, a second heddle, a two-way bracket, a connecting rod group and a dobby mechanism; the first heddle and the second heddle are installed on the bracket in pairs; the bracket Set side by side in parallel and connected with the heald frame; the upper and lower beams of the heald frame are respectively connected with multiple wooden frames; the heald frame is installed in the baffles on both sides of the loom; the heald frame is connected with the connecting rod group; connected; two-way brackets are arranged between adjacent heald frames, and the first heddle and the second heddle respectively pass through the two-way brackets; the two-way brackets are respectively connected to the upper and lower beams of the loom through nylon sheets and springs. The invention also provides a method for controlling the warp of the leno fabric. The invention has the advantages of being suitable for high-speed weaving of thick yarns, having clear openings and avoiding yarn scratching, etc., and has a simple and reasonable structural design.

Description

technical field [0001] The invention relates to the technical field of weaving equipment in the textile industry, in particular to a device and method for controlling the warp of a leno fabric on a loom. Background technique [0002] At present, the control device of the leno fabric warp thread is often equipped with a plurality of adjacent needle healds each with a warp thread guide eye and many elements with adjacent warp thread guide eyes. The warp yarn and the fixed needle heddles move crosswise according to the longitudinal direction of the needle healds. The element provided with the thread guide eye guides the longitudinal movement in the longitudinal direction of the needle heald and the transverse movement thereafter crosswise in the guide. For this type of equipment, the warp yarn guided by the above-mentioned elements moves alternately left and right of the needle, and multiple warp yarns move continuously and the warp yarns are alternately woven left and right. ...

AI Technical Summary

Problems solved by technology

For this type of equipment, the warp yarn guided by the above-mentioned elements moves alternately left and right of the needle, and multiple warp yarns move continuously and weave alternately left and right of the warp yarn continuously. This type of device is not suitable for high speed weaving due to the fraying of the yarn and the risk of weaving defects
