Description

A device for processing jacquard heald eyes and right heddle ears

technical field

The invention relates to the field of textile equipment, and is mainly used for processing a heald eye and a right heald ear of a jacquard heddle for a jacquard machine.

Background technique

Jacquard heald is the main consumable part of textile machinery, its quality directly affects the quality of cloth, and it is an indispensable part of jacquard machine. In the 1980s and 1990s, the equipment department of Henan No. 2 Textile Factory developed a jacquard heddle processing machine tool. Since the equipment department disintegrated later, this equipment was no longer produced. At present, there are still several small workshops processing healds with the machine tools produced before. The healds they produce are made of two iron wires twisted together, tinned, and then soldered with heald eyes in the middle. , The quality is large, and the weight of the jacquard machine is virtually increased, and the warp effect can no longer meet the current requirements for warp yarn. There are also textile accessories manufacturers that produce healds to replace healds. Due to the shape of the healds, the weaving density is limited and the warp ends are frequently broken. The invention proposes a novel jacquard heald processing machine tool. The processed healds are 0.8mm wide and 0.4mm thick, not only thin but also smooth in surface and good in warp effect.
