Benefits of technology

[0007] It is therefore a principal object of the present invention to provide a molded heddle which does not require extensive machining or polishing while providing enoug

Problems solved by technology

However, the metal heddles are limited by the fact that they are usually stamped or soldered, thereby limiting the configurations the heddles may possess.
The use of metal as material and the handling involved in preparing the metal heddles increases the cost of the heddles.
However, due to the size and tolerance limitations needed for the use of heddles in weaving machines, the heddles made from such plastics are more flimsy than

Abstract

Heddles for use within a harness frame of a weaving machine are provided. Each of the heddles includes a body formed from a liquid crystal polymer resin. The body forms at least one rod slot enabling engagement with a harness frame. The body also has an eyelet section with the eyelet section forming a yarn eye through which a yarn is capable of passing.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] N / A STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] N / A BACKGROUND [0003] The invention relates to a plastic heddle and, in particular, heddles molded from liquid crystal polymer resins. [0004] Heddles used within harness frames serve the purpose of controlling warp yarns in weaving machines. The warp yarns run through yarn eyes that are positioned intermediate of the ends of the respective heddles. As is commonly understood, a single warp yarn passes through the yarn eye of the heddle. The raising and lowering of different harness frames in which the heddles reside form sheds within a weaving machine to allow insertion of filling yarns to weave a fabric. The heddles are typically mounted on a support bar of a harness frame within the weaving machine. In this manner, the depth, or flat strip side, of the heddle is parallel to the direction of travel of the warp yarn. The eye of the heddle is typically rectangular ...
