Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a waste edge cutting device for a loom. Background Art

[0002] The rapier loom has strong adaptability to varieties because of its weft insertion method. It can adapt to the weft insertion of various types of yarns and is currently the most widely used shuttleless loom.

[0003] When a loom is producing machine-woven cloth, the weft yarn needs to be cut on at least one side of the cloth, resulting in the appearance of burrs on the weft yarn ends on that side, which is called waste edge. The waste edge needs to be cut and removed; the current waste edge cutting device includes a cutting tool, which remains in a fixed position during the cutting process in order to maintain the flatness of the cutting edge. At the same time, the purpose of cutting the cloth is to make the waste edge thread ends of uniform length by cutting the waste edge, and this process does not damage the main part of the cut cloth; in the process of cutting the waste edge of the cloth, the following problems are found: the waste edge thread ends of the cloth will not all be moved to the cutting tool in an orderly manner to complete the cutting, because some of the waste edge thread ends will bend or stick to the outer surface of the cloth during production, and these waste edge thread ends cannot contact the cutting position of the cutting tool, making this part unable to be effectively cut, and the remaining waste edge thread ends need to be trimmed again later, resulting in many trimming processes, high costs and affected production efficiency.

[0004] In summary, we consider how to further improve the effect and efficiency of waste edge cutting to reduce the problem that waste edge threads are bent or adhered to the fabric surface, which is not conducive to cutting waste edges; in view of this, we propose a loom waste edge cutting device.
