Abstract

PURPOSE:To prevent the twisting from occurring in weft yarn such as a foil, a film or another flat yarn when the weft yarn is fed between warp yarns in a weft yarn feeder for a loom. CONSTITUTION:A pair of round bars 1 and 2 extend substantially parallel at an interval and weft yarn such as a foil 4, a film or another flat yarn is passed through the respective round bars 1 and 2, alternately led to the respective round bars 1 and 2 and wound around the round bars 1 and 2 in one and opposite directions.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weft supply device for a shuttle loom, a rapier loom or other weaving machines for supplying weft threads such as foils, films or other flat threads between warps. .

[0002]

2. Description of the Related Art In a shuttle loom, a shuttle runs along a shuttle race and a weft is pulled out from the shuttle and supplied between the warps at each opening of the warp. It is well known that a woven fabric is woven by this. By the way, with regard to shuttle wefts, hitherto, the wefts have been wound around a tube in one direction, built into the shuttle, and when the shuttle runs along a shuttle race, the wefts have been pulled out in the axial direction of the tube. Therefore, the weft yarn is pulled out in a spiral shape around the pipe. Therefore, when the foil is used as the weft yarn, the foil is twisted and is supplied between the warp yarns. Therefore, there is a problem that the twist of the foil is scattered on the woven fabric and the appearance of the fabric is impaired.
Not only the foil but also a film or other flat yarn may be used as the weft yarn, but it is the same that the appearance of the woven fabric is impaired due to twisting of the film or other flat yarn.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent twisting of a weft when a weft such as foil, film or other flat yarn is fed between warps in a weft feeder of a loom. It was done for the purpose.

[0004]

According to the present invention, a pair of round bars extend substantially in parallel at intervals, and weft yarns such as foils, films or other flat yarns pass between the round bars and alternate to each round bar. And is wound around the bar in one direction and the other.

Description of Embodiments Embodiments of the present invention will be described below.

In FIG. 1, this is a weft supply device of a loom, which has a pair of round rods 1 and 2, and the rods 1 and 2 are tapered hollow ones and are spaced apart and extend substantially in parallel. , Substrate 3
It is fixed to. Furthermore, a foil 4 is used as a weft thread, which passes between the round bars 1 and 2, is alternately guided to the round bars 1 and 2, and is wound around the round bars 1 and 2 in one direction and the opposite direction. . In this embodiment, first, in one round bar 1, the foil 4 is wound around the round bar 1 in the clockwise direction, and it is guided to the other round bar 2 without passing between the round bars 1 and 2. Therefore, the foil 4 is wound around the round bar 2 in the clockwise direction, and then the foil 4 passes between the round bars 1 and 2 and is guided to one round bar 1. Therefore, the foil 4 is wound around the round bar 1 in the counterclockwise direction, and then the foil 4 is guided to the other round bar 2 without passing between the round bars 1 and 2. Therefore, the foil 4 is wound around the round bar 2 in the counterclockwise direction, passes through the round bars 1 and 2, and is guided to the one round bar 1. Therefore, the foil 4 is wound around the round bar 1 in the clockwise direction. This is sequentially and alternately repeated, and the foil 4 is wound around the round bars 1 and 2 in one direction and the opposite direction.

In the embodiment shown in FIG. 2, in one round bar 1, a foil 4 is wound around the round bar 1 in the clockwise direction, and it passes between the round bars 1 and 2 and is guided to the other round bar 2. Get burned. Therefore, the foil 4 is wound around the round bar 2 in the counterclockwise direction, passes through the round bars 1 and 2, and is guided to the one round bar 1. Therefore, the foil 4 is wound around the round bar 1 in the clockwise direction, and it passes between the round bars 1 and 2 and is guided to the other round bar 2.
Therefore, the foil 4 is wound around the round bar 2 in the counterclockwise direction, passes through the round bars 1 and 2, and is guided to the one round bar 1. Therefore, the foil 4 is wound around the round bar 1 in the clockwise direction. This is repeated alternately in sequence, and the foil 4 is round bar 1,
2 is wound in one direction and the other direction.

Therefore, for example, in a shuttle loom, as shown in FIG. 3, when the round bars 1 and 2, the substrate 3 and the foil 4 are built in the shuttle 5, the shuttle 5 is run along the shuttle race and the foil 4 is moved. When the foil 4 is pulled out from the shuttle 5, the foil 4 is wound around the round rods 1 and 2 in one direction and the opposite direction. Even if the foil 4 is pulled out in the axial direction of the round rods 1 and 2, the foil 4 is not twisted. Does not happen. Therefore, the foil 4 is not twisted and is supplied between the warp yarns so that the foil 4 is not twisted.
Woven fabric can be woven by. Therefore, the appearance of the fabric is not impaired.

Not only the foil 4 but also a film or other flat yarn may be used as the weft yarn. For film or other flat yarns, apply it to the rod 1,
When the film is wound around the rod 2 in one direction and in the opposite direction, the film or other flat yarn does not twist even if it is pulled out in the axial direction of the round bars 1 and 2, and the woven fabric is formed by the untwisted film or other flat yarn. Can be woven. Not only in the shuttle loom but also in a rapier loom or other loom, a weft yarn such as a foil 4, a film or other flat yarn is wound around the round rods 1 and 2 in one direction and in the opposite direction, and It may be withdrawn and supplied.

[0010]

As described above, according to the present invention, a weft yarn such as a foil 4, a film or other flat yarn is wound around the round rods 1 and 2 in one direction and the other direction. Therefore, even if the weft is pulled out in the axial direction of the round bars 1 and 2,
No twist occurs in the weft. Therefore, the weft can be twisted without being twisted, and the weft can be supplied between the warps to weave the woven fabric with the untwisted weft, and the desired appearance can be achieved without impairing the appearance of the woven fabric. Is.
