Yarn distributing device for weaving double-layer fabric

Abstract

The invention discloses a yarn distributing device for weaving a double-layer fabric. The yarn distributing device comprises a yarn distributing device wall plate, an upper layer shed ground warp lease rod bracket, a pile warp lease rod bracket, a lower layer shed ground warp lease rod bracket, yarn guide rollers and lease rods, wherein the upper layer shed ground warp lease rod bracket, the pile warp lease rod bracket and the lower layer shed ground warp lease rod bracket are arranged in sequence at upper, middle and lower positions of the yarn distributing device wall plate; the pile warp lease rod bracket, the upper layer shed ground warp lease rod bracket and the lower layer shed ground warp lease rod bracket are provided with yarn guide rollers and lease rods; and the yarn distributing device wall plate is provided with a transverse position adjusting groove and a longitudinal height adjusting groove. The back shed position of an upper layer ground warp is raised and the back shed position of a lower layer ground warp is lowered, so that two layers of warp have accordant elongation, the tension difference is reduced, and the uniform-tension weaving of the double-layer fabric is realized.

Description

Technical field [0001] The invention relates to a yarn dividing device for double-layer fabric weaving used on a loom, and belongs to the field of new textile machinery. technical background [0002] At present, all kinds of velveteen looms adopt the traditional warp position arrangement device for weaving double-layer fabrics. In this device, only one layer of warp yarn is lifted or lowered during the warp opening process, while the other layer of warp yarn does not move, so that the shed opening The shape always remains triangular, which causes the elongation of the upper and lower warp yarns to be different, resulting in excessive tension differences, resulting in unclear openings, affecting smooth weft insertion, and causing serious weaving defects in the fabric. Contents of the invention [0003] In order to meet the needs of double-layer fabric weaving of velveteen looms, especially high-speed looms, and improve the weaving quality of double-layer fabrics, the invent...
