Problems solved by technology

Such rapier heads are not suitable for this, they guide and clamp both weft threads in the same position, since this time the two weft threads may touch uncontrollably and rotation cannot be ruled out

Embodiment Construction

[0039] figure 1 Shown is a weft insertion rapier head 1 and devices 2, 3 by means of which one or two weft threads 4, 5 are simultaneously fed into the weft insertion rapier head 1 out of a plurality of weft threads. For example electrically driven devices 2 , 3 for graphic selection and yarn feeding can be freely programmed independently of each other by a controller 15 . It is also possible for more than two devices 2, 3 to be present and controlled by the controller 15 for being able to select from more weft yarns for each weaving cycle according to the pattern.

[0040] The different positions of the fed weft threads 4, 5 are achieved by the geometry of the devices 2, 3 in combination with different tasks for the travel of the guide needles (double arrows).

[0041] In this case, one end of each of the two weft threads 4, 5 is connected to its own storage drum, not shown, while the other end of the two ends is fastened together at the joining point of the fabric. After t...

Abstract

On a gripper weaving machine, two weft threads (4, 5) are selected simultaneously from a number of weft threads for a web cycle according to a pattern, and presented to a bringer gripper head, gripped by same, and introduced into a shed (22). The weft threads (4, 5) are guided and clamped in the bringer gripper head (1) by separate elements, and positioned in such a way that they remain separated during the introduction of the weft.

Description

technical field [0001] The present invention relates to a device and a method for introducing a weft thread on a rapier loom. It is provided here that two weft threads are selectively and simultaneously introduced into a shed according to a pattern, wherein these weft threads are kept apart from each other during the insertion of the weft threads. Background technique [0002] Various devices are known in the prior art for weaving machines for introducing the weft thread into the shed of the weaving machine by means of a rapier. It is generally provided that in each weaving cycle only a single weft thread is drawn out of the storage drum by the weft insertion rapier and brought to the middle of the shed, where it is picked up by the weft receiving rapier and transferred to the other side of the shed. Said shed consists of bundles of warp threads, which extend perpendicularly to the insertion of weft threads and are brought to different positions in a known manner, whereby a...
