[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, thus forming inferior cloth and increasing the production cost of the cloth

Embodiment 1
[0012] Embodiment 1: as figure 1 , 2 As shown, a let-off worm used on a loom includes a worm body 1, on which a screw thread 2 is arranged, and four arc-shaped protrusions are arranged on one end surface of the worm body 1, so that The two adjacent arc-shaped protrusions are connected by an indented arc 3 .
[0013] Wherein, for uniform warp let-off speed, the arc-shaped protrusions are symmetrically arranged in pairs.
[0014] Further, the four arc-shaped protrusions are respectively arc-shaped head A4, arc-shaped head B5, arc-shaped head C6 and arc-shaped head D7, and the arc-shaped head A4 and arc-shaped head B5, arc-shaped head C6 and arc-shaped head The shaped heads D7 are arranged horizontally and center-symmetrically, and the arc-shaped heads A4 and C6, the arc-shaped heads B5 and the arc-shaped heads D6 are arranged vertically and centerline symmetrically.
[0015] In the present invention, every quarter of the let-off worm's rotation, its arc-shaped projections per...

The invention discloses a let-off worm used on a loom, which comprises a worm body (1), on which a screw thread (2) is arranged, and on one end surface of the worm body (1), four threads are arranged. two arc-shaped protrusions, and two adjacent arc-shaped protrusions are connected by a concave arc (3). The invention has the advantages of simple structure, convenient manufacture and low cost. It can make the let-off speed of the warp keep up with the weaving speed, make the cloth surface tight and tight, prevent the vertical basket from falling off, and reduce the The formation reduces the weaving cost.
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...
