Problems solved by technology

The V-shape of this groove does not grip the cord effectively, which risks slipping while the loom is working, which makes the control of the heddles imprecise and can cause malfunctions in the shed
Furthermore, the grooves running over the entire length of the end piece make the end piece brittle in the region of the injection-molded strip of the heald
Additional end pieces have to be mounted on the lower part of the tubular part, thus complicating the installation operation

Embodiment Construction

[0038] The weaving machine M shown in Figure 1 is equipped with a Jacquard mechanism 2 which controls a plurality of threads 4, only one of which is shown and whose lower end is connected to a plurality of cords 6, the combination of which forms said The heald H of the loom. The lower end 6a of each cord 6 is connected to the upper end 8a of a heald 8 each provided with an eye 8b for the passage of warp threads 10 and subjected to the action of a return spring 12 fixed to the frame 14 of the loom by means of rods 16 .

[0039] The healds 8 can also be controlled individually by the mechanism 2, in which case each rope 6 is moved individually by means of this mechanism.

[0040] In the meaning of this specification, the adjective "upper" refers to the part or element of the device which is directed upwards in the normal configuration of use of the loom M, i.e. upwards in Fig. 1, while the adjective "lower" refers to the part or element which is directed downwards in this config...

Abstract

This device is used to hook together the healds (8) of a loom of the Jacquard type with the cord belonging to the harness of the loom. The device comprises an end piece (22) injection molded on the upper end (8a) of the heddle (8), which forms a hole (24) for the passage and wedging of the rope (6) and for Housing (228) that houses the two strands (6c) of the cord. The device also includes a rigid sleeve (24) mounted on said end piece (22), the sleeve (24) being translatable on this end piece between a first position and a second position, in the In one position the sleeve is allowed to approach the hole (224), in a second position the sleeve covers the hole and exerts a centripetal force that compresses the hole (224) and housing (228), thereby enabling blocking of the cord (6) the lower end. Such a device can also be used to hook one or more lines on a line.

Description

technical field [0001] The invention relates to a device for hooking a heddle on a harness of a loom of the Jacquard type or hooking a harness on a thread of a jacquard loom, and a jacquard loom equipped with such a device. The invention also relates to a method of producing such a device and a method of hooking a heald on a jacquard harness by means of such a device. Background technique [0002] The hook of a Jacquard machine is usually associated with a strip connected with one or more cords, the groups of which form the healds of the Jacquard machine. In its lower part, each cord must be hooked to the upper end of a heddle comprising eyes for the passage of warp threads. In order to realize the hooking, it is known from EP-A-0915195 to injection mold the end piece at the upper end of the heddle, which forms an opening for the passage and wedging of the lower end of the rope, and then a flexible sheath of synthetic material surrounds it. The end piece slides to assist i...
