Description

Technical Field

[0001] The present invention relates to the technical field of textile engineering, and specifically to a false selvage edge winding device for a rigid rapier loom. Background Art

[0002] Previously, using a fixture fastener to support the edge winding device was likely to cause wear and damage to the edge winding device, and was also likely to impact the reed and heddle frame, which would also cause wear and damage to the reed and heddle frame. At the same time, it was inconvenient for loom operators, machine repairmen, and maintenance personnel to operate. They needed to use a 2P iron hammer to impact and move it. After the transformation, with the use of a slide rail, slider, and edge winding seat, it is convenient for machine repairmen and loom operators to perform maintenance operations. They only need to loosen the screw and directly push it. At the same time, it can reduce the consumption of accessories. Summary of the Invention
