Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretchable member in which a lower hail wire is fixed in an elongated pipe and an upper hail wire is connected so that the upper wire can be moved in and out of the pipe. The present invention relates to a wire rod in a loom installed inside the pipe.

2. Description of the Related Art A thread is attached to the lower end of the needle so that the needle can be hooked by the vertical movement of the knife in the knife box of the jacquard machine, and a heald wire is hung from the hole in the eye plate and a wire is hung on the lower end. In the context of lower, hard and side needles and knives, up and down movements or arrow bars provide a restoring action. Therefore, the iron bar is traditionally made of lead or zinc-drawn iron wire and has a length of 21 cm to 30 cm.
The weight and the weight are in the range of 7.5 g to 26 g, and must be appropriately selected depending on the kind of the woven fabric.

However, in recent years, with the advent of an innovative loom, one using a spring has been proposed.

[Problems to be Solved by the Invention] Since the arrow bar of the conventional loom is hung on the heald wire, the arrow bars oscillate left and right and are entangled with each other due to the vibration and vertical movement of the loom, which hinders the weaving of the fabric. Yes, this was also a big problem.

Further, in the springs of the innovative fabrics in recent years, there is a problem in that the movement of the loom is vigorous, so that thread scraps (fluff balls) attach to the springs and deteriorate the function of the springs.

Therefore, the present invention intends to provide a loom without weaving scratches on the woven fabric, by attaching the cotton swabs that do not occur during the motion of the loom and smoothly performing the returning action together with the smooth jacquard movement. Is intended.

Means for Solving the Problems In order to achieve the above object, in the arrow bar of the present invention,
An elastic member such as a spring is connected to both ends of each of the respective heald wires, one of the heald wires is inserted into an elongated pipe, and the upper end of the pipe is slightly narrowed from the outer periphery, so that at least one portion is formed. Although the above-mentioned bulging portion is formed to allow the above-mentioned heald wire to move in and out of the pipe, and at the same time to expand and contract the spring in the pipe, the connecting portion between the lower heald wire and the spring is fastened and fixed at the lower end portion of the pipe. Only the wire is projected to the outside and attached to the mounting plate so as not to go in and out.

Further, rubber or the like can be used as the elastic member.

Further, for the same purpose, two or more bulging portions may be formed above the pipe at predetermined intervals.

Action Unlike the conventional movement, the arrow wire constructed as above
As the elastic member is installed inside the pipe, when the jacquard is driven, the hard needle does not get caught by the knife, and when it is free, the elastic force of the elastic member causes it to descend, and the hard needle catches the knife and rises. At this time, the elastic member expands in the pipe due to the tension of the heald wire.

Further, for the above reason, the heald wire is one in which the elastic member in the pipe performs the same returning action as the conventional arrow wire, and the pipe is attached to the mounting plate via the lower heald wire. Therefore, the pipes do not collide with each other to give a shock, and the pipes independently operate smoothly.

Embodiment An embodiment will be described with reference to the drawings. FIG. 1 is a schematic view of a conventional single-acting jacquard. FIG. 2 shows an embodiment of the present invention, which is an elongated pipe (1), which uses a vinyl pipe exclusively, and a part of the upper end of the pipe (1) is slightly constricted around the outer circumference to bulge out. 2) At least one is formed. This bulge (2) is driven by the loom.
When the heald wire (4) descends, etc., cotton debris is sucked and accumulated together with the suction force of air.
(3) is a stretchable member, the spring (3) is inserted into the pipe (1) with the upper hail wire (4) above the spring (3) exclusively using the spring (3).
The heald wire is connected to
Connect the upper end of (4) to the thread (6). (5) is a lower heald wire, one end of which is connected to the lower end of the spring (3), and the connecting portion is tightened and fixed from the outer periphery of the lower end of the pipe (1), and the wire (5 ) Is hung downward and fixed to the mounting plate (7). The embodiment shown in FIG. 3 is a schematic diagram illustrating the mounting state of the pipe (1) of FIG.
Attach one end of the thread (6) to the lower end of the hard needle (9) provided in the jacquard (8), and attach the other end of the thread (6) to the hole of the eye plate (10).
Pass it through (11), tie the upper end of the upper hail wire (4) to it, insert it into the pipe (1) as shown in FIG. 2, and attach it to the spring (3). Attach the upper end of the lower hail wire (5) to the lower end, and tighten and fix it at the lower end of the pipe (1).
Fix the lower end of (5) to the mounting plate (7). The spring (3) in the pipe is expanded and contracted by the vertical movement of the heald wire (4) in association with the movement of the jacquard, and the fabric is woven by the loom.

FIG. 4 shows another embodiment, in which two bulging portions are formed in the upper part of the pipe (1), a heald wire is inserted into each pipe, and a spring having a force-accumulating force is formed below. The built-in structure and other configurations are the same as those in FIGS. 2 and 3.

EFFECT OF THE INVENTION Since the present invention is configured as described above,
The following effects are achieved.

Since the bulging part (2) is formed by narrowing the outer circumference of the upper part of the pipe, even if a cotton swab (cotton dust) or the like is sucked into the pipe, it will remain in the bulging part and inside the pipe. Since it does not descend, the raising / lowering action (returning action) of the heald wire is smoothly performed.

Further, since the cotton swab is not required for the spring in the pipe, the expansion and contraction action of the spring is smooth, so that the loom is smoothly operated and the woven fabric is not damaged.

Further, since the upper and lower heald wires are fixed at the upper and lower sides, there is no risk of adjacent pipes coming into contact with each other and winding, or being entangled with each other to hinder the movement.
