A weft feeding mechanism of a rapier loom

Abstract

The invention discloses a beating-up mechanism of a rapier loom. The beating-up mechanism of the rapier loom comprises a giver and a first weft insertion device and a second weft insertion device; the first weft insertion device and the second weft insertion device are respectively installed on both ends of a rapier loom frame and correspond to each other; a giver is mounted on the frame and located between the first weft insertion device and the second weft insertion device and corresponds to the first weft insertion device. The beating-up mechanism of the rapier loom can realize the elicitation of two wefts by the giver at a time, and reduce the movement time of the giver and improve the efficiency; the wefts do not need to be cut in the weaving process, the weft strength at both ends of the cloth is ensured, and the use of a trimming mechanism on the rapier loom is reduced, thereby the maintenance cost of the rapier loom is reduced.

Description

technical field [0001] The invention relates to the field of weaving, in particular to a weft feeding mechanism of a rapier loom. Background technique [0002] A loom is a mechanical device that processes various natural fibers into textiles. There are various types of looms and various functions. Most looms have the following parts to form shedding unit, weft insertion unit, weft beating unit, take-up unit, warp let-off unit, protection device, etc. For fabrics that require double-strand weft threads, it is generally realized by two weft-feeding swords. Because the weft-feeding sword needs two movements, it takes a long time, and because the weft-feeding sword cuts the weft thread sent for the first time, there is no Under the action of external force, the weft will shrink and cannot be kept in a straight line, so that the quality of the woven fabric is not good enough. Contents of the invention [0003] The purpose of the present invention is to provide a weft-feeding ...
