Abstract
A heddle (1) for flat, band-shaped warp threads (36) is provided with a thread eyelet (7), for which the width preferably exceeds the height. A thread eyelet (7) of this type prevents a deformation of the band-shaped warp thread (36), in particular a compressing on the sides during the shed formation. In addition, the heddle (1) according to the invention is preferably provided with thread guiding surfaces, which are longer than the thickness of the heddle (1) body (3), relative to the running direction of the warp thread. As a result of these measures, the wear on the heddle (1) as well as the warp thread (36) can be reduced.
Claims11
A heddle for band-shaped warp threads comprising,
- a heddle body that extends in a longitudinal direction and is provided on at least one end with an end eyelet for positioning it on a heddle support rail,
- a rectangular thread eyelet provided on the heddle body, and having an upper edge and a lower edge, wherein these edges are spaced apart in the longitudinal direction,
- wherein only the upper edge and the lower edge form a thread guiding surface, which is embodied rounded on the thread inlet side and/or the thread outlet side, and wherein the length of the guiding surface extending in a warp thread movement direction exceeds the thickness, measured in the same direction, of the heddle body at the thread eyelet.
