Warp feeding worm used on loom

Abstract

The invention discloses a warp feeding worm used on a loom. The warp feeding worm used on the loom comprises a worm body (1), wherein threads (2) are arranged on the body, four arc-shaped protrusions are arranged on the end face of one end of the worm body (1), and every two adjacent arc-shaped protrusions are connected through an inwards-concave arc (3). The warp feeding worm used on the loom has the advantages of being simple in structure, convenient to manufacture and low in cost, the warp feeding speed can be kept pace with the weaving speed by means of the warp feeding worm, so that the cloth surface of cloth is appropriate in tightness, the phenomenon that a longitudinal basket drops is prevented, the forming rate of inferior-quality cloth is reduced, and weaving cost is reduced.

Description

technical field [0001] The invention relates to a loom, in particular to a warp let-off worm used on the loom. Background technique [0002] At present, on the existing looms, a let-off worm is required for the transmission of warp threads. The existing let-off worm mainly includes a worm body, on which a screw thread is arranged, and on one end of the worm body there are two Arc-shaped heads, due to the large distance between the arc-shaped heads, during the weaving process, the delivery of warp threads cannot keep up, so that the fabric weaves is tight and the tension is large, and the vertical basket of the loom will fall off. Once the vertical basket is taken off, problems such as warp shrinkage and warp breakage will occur on the cloth surface, thereby forming inferior cloth and increasing the production cost of the cloth. Contents of the invention [0003] The object of the present invention is to provide a warp let-off screw used on a loom that can make the warp ke...
