Embodiment Construction

[0035] figure 1 The loom 2 shown in is configured to weave a fabric T having a thickness eT greater than 5 mm, for example about 10 mm.

[0036] The loom 2 comprises a warp beam 4 from which warp threads 6 are unwound, and a take-up roll 8 intended to receive a fabric T. As shown in FIG.

[0037] A system for inserting warp threads, not shown and known per se, gives the possibility of letting the warp threads enter a shed F defined between the warp threads 6 .

[0038] Each warp thread passes through the eyelet of the heddle 10, the vertical position of which is controlled by a mechanism 12 for forming the shed, which consists of a jacquard mechanism 14 and an arch 18 which passes through a guide plate 20, a mesh plate 22 and a return spring 26 Formation 16. Each heald 10 is suspended to the arch 18 and is connected at the lower part to the fixed frame 24 of the loom 2 by a return spring 26 which tends to pull the heald downwards against the pressure caused by the correspond...

Abstract

This heddle for a harness of a Jacquard weaving loom comprises two strands 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 with aneyelet for guiding a warp thread, this eyelet being positioned, along a longitudinal axis of the heddle, between both strands. The link is in a synthetic material and comprises two branches positionedon either side of the eyelet along the longitudinal axis. A portion of each branch is over-molded on a second end of a strand opposite to its first end and shifted longitudinally from the eyelet. Further, each branch of the link completely surrounds the second end of the corresponding strand. The second end of the strand is conformed with a geometry intended to achieve an anchoring which opposesthe 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, while the eyelet is formed with the synthetic material which makes up the link.

Description

technical field [0001] The invention relates to a heald for the healds of a loom of the Jacquard type. Background technique [0002] In the field of shedding on looms of the Jacquard type, it is known how to use healds to move the warp threads of the loom vertically. The heddles are usually equipped with eyelets for guiding the warp threads, the material and shape of which are chosen so as not to damage the warp threads passing through the eyelets and not to wear out under the friction that advances the warp threads. [0003] For example, EP-A-1 767 676 teaches how to insert an eyelet of carbon steel into a hole formed by a longitudinal body of stainless steel. In the region of the longitudinal body defining the connecting piece in which the eyelet is positioned, the interaction takes place as the warp passes through the eyelet and as the adjacent warp thread passes through the eyelet of the adjacent heddle. In the mechanism used to form the shed, the eyelets of the handli...
