Embodiment Construction

[0016] The used rapier device of the sackcloth rapier loom of the present invention is an arc rapier device. Said arc rapier device such as figure 1 , 2 , 3, and 4, it is composed of curved rapier strip 1, curved rapier strip 2, rapier tube 4, rapier mouth plate 3, rapier head 9, yarn guide 7, and rapier drive plate 5 of. The outer side of the arc-shaped rapier bar, that is, the bow back is covered with an arc-shaped rapier lining strip, and the outer edge of the radial section of the arc-shaped rapier lining strip is a circular arc, which makes the rapier bow back smooth. The rapier tube is installed on the inside of the curved rapier bar, that is, on the belly of the bow, and is a tube with a smooth inner wall. One end of the arc-shaped rapier bar is fixedly installed with a rapier drive plate, or in other words, one end of the arc-shaped rapier bar is fixed on the rapier drive plate, and the rapier head is on the other end of the arc-shaped rapier bar. The end of the ar...

Abstract

The invention provides a sackcloth rapier loom comprising a pair of rapiers (I), a heald frame and reeds (15). Either rapier (I) enables weft yarns to be woven into warp yarns (16) and is provided with a rapier head with a weft yarn outlet; the rapier heads of the rapiers (I) are mounted in opposite directions, wherein either rapier (I) is bent in an arc, and the weft yarn outlet is arranged at the inner side of the arc; the chord length of either rapier (I) is larger than the breadth of woven sackcloth (II); the two rapiers (I) are mounted on a central shaft (11) in the circle center of the arcs by rapier arms (10); the central shaft (11) and the heald frame lift the warp yarns (16) in parallel directions; a swinging arm (12) using the central shaft (11) as a rotating shaft is fixedly connected with the rapier arms (10); and a swinging angle of the swinging arm (12) is larger than a central angle occupied by the breadth of the woven sackcloth (II) on the trace of the rapier heads. Compared with the prior art, a pair of driving mechanisms can simultaneously drive the two rapiers to work, thereby the invention lowers noise, reduces energy consumption, improves the motion stability of the rapiers and also decreases the manufacture material consumption of the loom and the labor cost.

Description

technical field [0001] The invention relates to a sackcloth rapier loom, in particular to a rapier structure of the sackcloth rapier loom, and belongs to the technical field of textile looms. Background technique [0002] In the field of sackcloth weaving, in order to overcome many defects of the shuttle loom, a straight-running rapier loom has been proposed. The straight-running rapier loom has a weft-feeding sword and a weft-connecting sword composed of a rapier and a rapier head. The two swords advance and retreat relatively on the same straight line and are interspersed in the shedway formed by the heald frame pulling the warp yarn to weave the weft yarn on the warp yarn. In between, there is another reed to determine the distance between the warp yarns and play the role of beating up according to the action of the warp yarns. In this structure loom, the driving mechanism for the interspersed action of the weft feeding sword and the weft receiving sword is based on the ...
