Heddle for loom, loom equipped with such a heddle and process for manufacturing such a heddle
A heddle for guiding a warp yarn for a loom extends lengthwise along a longitudinal axis (X1) and has a heddle body including at least one strand and at least one eye including an eyelet for the passage of the warp yarn and wherein the heddle body includes at least one housing, the housing of the eye and the housing of the heddle body extend along a common axis (Z1) transverse to the longitudinal axis, the housing of the heddle body is across from the housing of the eye, and the housings together forming a pair of housings and wherein an assembly member made from solidified resin is positioned in the pair of housings.
Heddle for Jacquard loom, method of manufacturing the heddle, and weaving loom including such a heddle
Heddle for a harness of a Jacquard weaving loom having two strands (32, 34) each equipped at a first end with a member for hooking-up the heddle to an element 10 of the harness, as well as a link (30) with an eyelet (36) for guiding a warp thread, this eyelet (36) being positioned, along a longitudinal axis (XI0) of the heddle, between both strands (32, 34). The link (30) is in a synthetic material and has two branches (52, 54) positioned on either side of the eyelet (36) along the longitudinal axis (XI0). A portion (522, 542) of each branch (52, 54) is over-molded on a second end (324, 344) of a strand (32, 34) opposite to its first end and shifted longitudinally from the eyelet (36). Further, each branch (52, 54) of the link completely surrounds the second end (324, 344) of the corresponding strand (32, 34). The second end of the strand (32, 34) is conformed with a geometry intended to achieve an anchoring which opposes the displacement of the overmolded portion of the branch of the link relatively to the second end of the strand along two opposite longitudinal directions (FI, F2), while the eyelet (36) is formed with the synthetic material which makes up the link (30).
HEDDLE FOR WEAVING LOOM AND WEAVING LOOM PROVIDED WITH SUCH A HEDDLE
This heddle comprises a link and at least one rod made of polymeric material, one longitudinal extremity of which comprises surfaces covering the transverse faces of the link. The rod and the link form at least one cavity, offset from the link parallel to a longitudinal axis and delimited by a first peripheral surface of the link, a second lateral surface, formed by the outer surface of the rod, and a third bottom surface, formed by the rod and extending one of the covering surfaces. An intersection line extends from the third bottom surface and delimits the first surface. The third bottom surface is arranged toward the outside of the rod relative to the second lateral surface. Each cavity is non-facing, according to a thickness axis in a direction away from the third bottom surface.
HEDDLE FOR JACQUARD LOOM, METHOD OF MANUFACTURING THE HEDDLE, AND WEAVING LOOM INCLUDING SUCH A HEDDLE
This heddle for a harness of a Jacquard weaving loom comprises two strands (32, 34) each equipped at a first end with a member for hooking-up the heddle to an element of the harness, as well as a link (30) with an eyelet (36) for guiding a warp thread, this eyelet (36) being positioned, along a longitudinal axis (X10) of the heddle, between both strands (32, 34). The link (30) is in a synthetic material and comprises two branches (52, 54) positioned on either side of the eyelet (36) along the longitudinal axis (X10). A portion (522, 542) of each branch (52, 54) is over-molded on a second end (324, 344) of a strand (32, 34) opposite to its first end and shifted longitudinally from the eyelet (36). Further, each branch (52, 54) of the link completely surrounds the second end (324, 344) of the corresponding strand (32, 34). The second end of the strand (32, 34) is conformed with a geometry intended to achieve an anchoring which opposes the displacement of the over-molded portion of the branch of the link relatively to the second end of the strand along two opposite longitudinal directions (F1, F2), while the eyelet (36) is formed with the synthetic material which makes up the link (30).
JACQUARD HEDDLE AND LOOM COMPRISING SUCH A JACQUARD HEDDLE
A Jacquard heddle comprising a link, comprising an upper hole and a lower hole of circular cross-section. A first single-filament wire is engaged in the upper hole forming an upper loop and a second single-filament wire is engaged in the lower hole forming a lower loop. The Jacquard heddle comprises an upper end connector to which two end portions of the first wire are linked and a lower end connector to which two end portions of the second wire are linked. The upper loop defines a free opening extending from the upper hole to the connection of the two end portions of the first wire with the upper end connector. The lower loop defines a free opening extending from the lower hole to the connection of the two end portions of the second wire with the lower end connector.
Heddle for weaving loom and weaving loom provided with such a heddle
This heddle includes a link and at least one rod made of polymeric material, one longitudinal extremity of which includes surfaces covering the transverse faces of the link. The rod and the link form at least one cavity, offset from the link parallel to a longitudinal axis and delimited by a first peripheral surface of the link, a second lateral surface, formed by the outer surface of the rod, and a third bottom surface, formed by the rod and extending one of the covering surfaces. An intersection line extends from the third bottom surface and delimits the first surface. The third bottom surface is arranged toward the outside of the rod relative to the second lateral surface. Each cavity is non-facing, according to a thickness axis in a direction away from the third bottom surface.

PLASTIC HEALDS WITH MULTIPLE EYES
The present invention provides a heald suitable for use with various types of weaving looms. The heald is constructed from plastics having two distinct colors which meet around the middle of the heald so that each color includes an eye for guiding the warp threads. The edges and sides of the heald are arced and radiused to reduce friction from passing up and down through the yarns to allow for faster machine operation. In some embodiments, the top end of the heald is constructed and arranged to grip the operational cords typically used on a Jacquard weaving machine. The grip end of the heald includes a sinusoidal path and alligator like teeth to prevent slipping of the cords.
