Abstract
A rod-like yarn guiding heald is made of a compact thermoplastic reinforced with industrial continuous fibers. The fiber reinforcement is in the form of a flattened braided flexible tube. An eye opening is contrived by opening up the braided fiber strands. The yarn guiding heald is of light weight and high strength. A ceramic insert may also be inserted into the opening of the yarn guiding heald for special yarns.
Claims17
A rod like yarn guiding element for textile machinery comprising
- an elongated compact thermoplastic body of flat cross-sectional shape, having a transversely oriented eye opening in an intermediate zone for passage of a yarn therethrough;
- and
- a braided tube or continuous fibers reinforcing said thermoplastic body, said tube having said fibers thereof disposed about said opening.
A heald for a loom comprising
- an elongated flat thermoplastic body having an traverse opening for passage of a yarn therethrough in a intermediate zone thereof, a pair of end zones and an opening in each end zone;
- and
- a flattened braided tube of continuous fibers extending longitudinally of and within said body to reinforce said body, said tube having crossing strands of fibers thereof displaced about each said opening of said intermediate zone and a respective end zone.
A rod like yarn guiding element for textile machinery comprising
- an elongated compact thermoplastic body having a transversely oriented eye opening in an intermediate zone for passage of a yarn therethrough;
- and
- a braided tube of continuous fibers reinforcing said thermoplastic body and disposed about said opening, said tube having said fibers thereof disposed on an inclined angle of less than 45 degrees relative to a longitudinal axis of said body.
A rod like yarn body element for textile machinery comprising
- an elongated compact thermoplastic body of flat cross-sectional shape having a transversely oriented eye opening in an intermediate zone for passage of a yarn therethrough, said intermediate zone being twisted relative to a pair of end zones of said body;
- and
- a braided tube of continuous fibers reinforcing said thermoplastic body, said tube having said fibers thereof disposed about said opening.
