Device and method for controlling warp yarns of gauze cloth on loom

Abstract

The invention discloses a device and a method for controlling warp yarns of gauze cloth on a loom, and belongs to the technical field of braiding equipments in the textile industry. The device comprises a plurality of heald frames, brackets, first healds, second healds, two-way brackets, linkages and multi-arm mechanisms, wherein the first healds and the second healds are mounted on the brackets front and back in pairs; the brackets are arranged in parallel side by side, and are connected with the heald frames; upper cross beams and lower cross beams of the brackets are respectively connected with a plurality of wooden frames; the heald frames are mounted in baffles on the two sides of the loom; the heald frames are connected with the linkages; the linkages are connected with the multi-arm mechanisms; the two-way brackets are arranged between the adjacent heald frames; the first healds and the second healds respectively pass through the two-way brackets; the two-way brackets are respectively connected with the upper cross beam and the lower cross beam of the loom through nylon pieces and springs. The invention further provides the method for controlling the warp yarns of the gauze cloth. The device and the method have the advantages that the device is suitable for the high-speed weaving of thick yarns, the opening is clear, the friction of yarns is avoided, and the structural design is simple and reasonable.

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
