Abstract
A simple removable plastic heddle comprised of a single monolithic plastic body and a mating insertion tool.
Claims3
A weaving heddle constructed as a single monolithic body, capable of being installed and removed in a loom by axial motion parallel to the principal axis of the heddle, and comprised of:
- (a) two end features for engaging a means for a heddle supporting frame, said features providing controlled restraint of axial, rotational, and one orthogonal motion of the monolithic body relative to it's principal long axis, and
- (b) said controlled restraint provided by the shape of the end features as they interface with the supporting frame, and the allowable bending properties of the monolithic body during and after installation, and
- (c) a central feature that allows the installation and removal of an untensioned warp element by lateral motion through an inclined slot in the exterior wall of a rectangular shaped constraining enclosure, said constraint acting orthogonal to the tensioned warp element after installation.
