Abstract
The gripper projectile has a housing (1), a weft yarn clip (2) and a connector element (3) in order to connect the housing and the weft yarn clip. Furthermore, unitary portions protruding outward from the outer side of each respective leg are provided for biasing the clip legs in order to produce a predetermined gripping force, with the gripping force setting itself automatically on assembly of the weft yarn clip.
Claims14
A weaving machine comprising:
- a gripper projectile including a housing formed as a hollow body;
- and a weft yarn clip arranged in the housing, having a line of symmetry, and a connector element connecting the housing to the weft yarn clip so that the weft yarn clip and the housing are prevented from moving relative to each other along the line of symmetry, the weft yarn clip comprising a pair of legs defining between them a jaw for gripping a yarn and having a recess for splaying the jaws, a yoke connecting the legs and unitary protruding portions on the legs, formed identically relative to the line of symmetry, for bringing the clip legs into operative engagement with the housing and thereby biasing the clip legs toward one another in order to generate a predetermined gripping force at the jaw.
