Edge weaving device of weaving machine

Abstract

The invention relates to an edge weaving device of a weaving machine, in particular to an edge weaving device of the weaving machine for weaving leno edges. The edge weaving device comprises an upper yarn guide and a lower yarn guide, wherein the upper yarn guide vertically swings and also transversely swings intermittently, and the lower yarn guide vertically swings. The upper yarn guide and the lower yarn guide vertically swing to form a back-and-forth crossed opening identical to the cloth fell size and the opening time of the weaving machine, accordingly two edge weaving yarns form a leno weave in the crossing changing process without leno healds, and therefore weaving motion of the weaving machine is simplified, reciprocating motion of a motor is avoided, control programs of the motor are greatly simplified, service life of the motor is prolonged, rotating speed of the weaving machine is greatly improved, and the edge weaving device is suitable for a new generation of water spray high-speed weaving machine. The edge weaving device is simple in structure and compact and stable in transmission, reduces fault rate of the weaving machine, greatly shortens the stroke of an edge weaving mechanism, accordingly shortens the yarn reciprocating motion path, is favorable for controlling yarn tension, reduces yarn breaking, improves the production efficiency of the weaving machine, and meets market demands.

Description

technical field [0001] The invention relates to a loom selvedge device, in particular to a loom selvedge device for weaving saros, in particular to making two edge yarns form a simple leno weave in the process of intersecting change without the need for Selvedge mechanism for leno healds. Background technique [0002] The selvedge devices commonly used in general looms include a planetary gear selvage mechanism or a leno heddle selvedge mechanism. [0003] The leno heald weaving mechanism uses one or several sets of skeined warp yarns to twist with the ground warp yarns at the selvedge, and at the same time interweaves with the weft yarns to form a leno edge selvage form. Because the skeined warp yarns and the ground warp yarns are intertwined with each other, the enveloping angle and extrusion force between the selvedge warp and weft yarns, and between the skeined warp yarns and the ground warp yarns are increased, and the mutual control ability of the warp and weft yarns ...

AI Technical Summary

Problems solved by technology

However, the rotation of the leno yarn cannot be in a single direction, otherwise the yarn will be twisted, and the yarn will be easily broken when it reaches a certain level. A motor that can rotate back and forth should be used, and the reciprocating motion of the motor will increase the heat generated by the motor during work, reducing the life of the motor

Furthermore, the rotational movement of the leno yarn has a relatively large stroke, so it requires a large space for movement, and also increases the movement path of the yarn, which is not conducive to the tension control of the yarn.
