Abstract
This invention relates to a heddle formed in a metal band or strip which comprises an eyelet for passage of a warp yarn and presents, over substantially the whole of a zone included between this eyelet and a first end by which it is connected to a drive means, a cross-section substantially in the shape of a Z, with two branches substantially parallel to each other.

Heddle for a weaving loom, the heddle comprising;
- an elongated body having an eyelet therethrough for passage of a warp yarn and a body portion which extends between said eyelet and a first end of said body by way of which the body is connected to a drive means, said body portion having a substantially Z-shaped cross-section taken perpendicularly with respect to an elongated axis (X-X′) of said elongated body along at least a substantial length thereof so as to define two elongated flanges which are offset and substantially parallel to each other.
Process for manufacturing a heddle for a weaving loom, wherein the heddle is formed of a metal band or strip comprising an eyelet for passage of a warp yarn and which eyelet is spaced from a first end by way of which the heddle is fastened to a drive means, wherein said process comprises a step consisting in rolling or drawing the metal band or strip to form two generally parallel elongated flanges extending on either side of a median elongated axis (X-X′) of the heddle and such that a cross-section through the heddle and perpendicular to said longitudinal axis is generally Z-shaped.
Weaving loom comprising:
- a shed-forming devices, said shed-forming device including at least one heddle, said at least one heddle including an elongated body having an eyelet therethrough for passage of a warp yarn and a body portion which extends between said eyelet and a first end of said body by way of which the body is connected to a drive means, said body portion having a substantially Z-shaped cross-section, taken perpendicularly with respect to an elongated axis (X-X′) of said elongated body, along at least a substantial length thereof so as to define two elongated flanges which are offset and substantially parallel to each other.
