Background

Heddles are the main consumable accessories used in weaving machines, which work in wet, wet environments. The traditional material for manufacturing the heddles is mainly austenitic stainless steel, and the austenitic stainless steel is not common at present because the raw material price is high and the processing cost is high. In order to solve the defects of the stainless steel heald, the heald on the market at present is produced into a sheet heald semi-finished product by adopting thermoplastic plastics and an injection molding method.

The upper, middle and lower positions of each heddle are provided with three ring holes, and the upper ring hole and the lower ring hole are used for penetrating the heddle or hanging the heddle; the middle ring hole is called a heddle eye, so that the warp yarns can pass through the middle ring hole. Hundreds of heddles are combined into a heald frame by a heald bar or a hanging rod, and when the heddles move up and down, the warp yarns threaded in the heald eyes are separated into yarn layers and form a shed, so that weft yarns penetrate and are interwoven with the warp yarns to form a fabric. In order to make the warp thread smoothly penetrate into the heddle eye manually or mechanically, a local twist is generated at the heddle eye position of each heddle. The traditional stainless steel heald is realized by twisting a die, and for a sheet of plastic heald semi-finished product, a novel heald eye hot twisting die assembly suitable for the plastic heald needs to be designed because a heald eye is difficult to twist during injection molding.
