Abstract
A weaving heddle formed of a strip of material has end eyes adjacent opposing end sections of the heddle and a central thread eyelet. The spaced apart legs forming the long sides of the heddle eyes extend transversely outwardly of the opposing edges of the strip from which the heddle is made, and in the area of at least one of the short sides of the rectangular end eye is an auxiliary squeeze-pressed section at a spaced apart distance therefrom providing a separating ridge located between the short side of the end eye and the auxiliary pressed section(s). The ridge is oriented such that its base is perpendicular to the longitudinal axis of the heddle.
Claims18
A weaving heddle comprising, an elongated strip of material having an initial constant width extending between opposing terminal ends thereof, said strip having squeeze pressed and punched out end sections forming end eyes adjacent said terminal ends, each said end eye having opposing ends and each said end eye being defined by a pair of spaced apart side legs lying parallel to the longitudinal axis of the strip, said side legs having outer edges extending laterally outwardly of opposed outer edges of said strip defining said constant width, and at least one of opposing faces of said strip having at least one auxiliary pressed section adjacent one of said opposing ends of each of said end eyes.
A process of making end eyes of a weaving heddle having a central thread eyelet, comprising the steps of:
- providing an elongated strip of material having an initial constant width and having opposing faces;
- compressing together localized areas at opposing faces of the strip at end sections thereof for initially forming opposed elongated indentations lying along a longitudinal axis of the strip;
- forming side legs by the compressing step at said indentations such that outer edges of said side legs extending laterally outwardly of opposed outer edges of said strip defining said constant width;
- punching out the material at said elongated indentations to form said end eyes at said end sections with each of said end eyes having opposing ends, and
- applying at least one deformation to at least one of said opposing faces of said strip to define an auxiliary indentation adjacent one of said opposing ends of each of said end eyes.
