Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pair of front and rear ear thread healds which reciprocate in opposite directions by passing through a jacquard device and a pair of reciprocating ear thread healds. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leno ear forming device that includes a leno forming mechanism including a reciprocating semi-heald, and causes a pair of ear threads to perform leno ear forming operation by reciprocating the semi-heald.

[0002]

2. Description of the Related Art Such a twine ear forming apparatus is disclosed in
19537. The semi-heald is made of a magnetic material and has a forked shape. A slit is formed at the lower side of the pair of front and rear healds, and a half heald is inserted into the slit of each heald. At the lower end of each heald, a pair of magnets are arranged facing each other across the lower end of the slit,
One of the lower ends of the bifurcated legs of the semi-heald is attracted and held by the magnet. When the height of the front and rear healds is the same, the lower ends of the forked legs of the half heald are in positions where both magnets are attracted to the magnet. The lower end of the abutment comes into contact with the lower end of the foot of the semi-heald to carry the semi-heald. Next, when the same heald is lowered, the half heald adsorbed by the magnet on the heald side is also lowered. An advantage of the twining ear forming device having such a configuration is that it can be reduced in weight.

[0003]

There is no problem when such a twine ear forming device is used by attaching it to a heald frame. However, when the heald is suspended by a thread and used by a Jacquard loom in such a manner that the heald is urged downward by a spring, the half heald tends to come off from the front and rear healds. The semi-heald is merely attracted to the front and rear healds only by the magnetic force of the magnet, and the vibration of the heald accompanying the high-speed vertical movement of the front and rear healds causes the semi-heald to deviate from the heald.

[0004] It is an object of the present invention to provide a leech ear forming device in which a semi-heald is unlikely to come off the heald.

[0005]

For this purpose, the present invention provides a pair of ear thread healds which reciprocate in opposite directions by passing through a jacquard device and a pair of reciprocating ear thread healds. 2. The invention according to claim 1, further comprising a twine ear forming mechanism including a half heald that is entrained and reciprocally moved, and a twine ear forming apparatus that performs a twine ear forming operation on a pair of ear threads by reciprocating movement of the half heald. A first path stabilizing means for stabilizing a reciprocating path between the first ear thread healds of a plurality of adjacent ear ear forming mechanisms; And a second path stabilizing means for stabilizing the reciprocating path of the ear.

[0006] The reciprocating path of the first ear thread healds of the plurality of twine ear forming mechanisms is stabilized by the first path stabilizing means. Second of multiple adjacent ear formation mechanisms
The reciprocating path of the heald for ear thread can be stabilized by the second path stabilizing means. The stability of the reciprocating path prevents the half heald from coming off the ear thread heald.

According to the second aspect of the present invention, a path stabilizer for connecting one end of the adjacent first ear thread heald is adopted as the first path stabilizing means, and the adjacent second ear thread heald is used. A path stabilizing member connecting one end is employed as the second path stabilizing means.

The path stabilizer connects one end of the adjacent heald for ear thread, and the pair of adjacent heald for ear thread and the path stabilizer form a square U-shaped frame shape having three sides. Such a frame shape stabilizes the reciprocating path of the heald for the ear thread.

In the invention of claim 3, the first path stabilizer and the second path stabilizer are slidably connected to each other. The slide connection configuration of the first path stabilizer and the second path stabilizer contributes to stabilization of the reciprocating path of each ear thread heald.

In the invention according to claim 4, an auxiliary eye plate for slidingly guiding each heald for each ear thread is employed as the first path stabilizing means and the second path stabilizing means. The auxiliary stitches stabilize the reciprocating path of each ear thread heddle.

There is no danger of being disengaged from 22. (1-2) The path stabilizing plates 25 and 26 made of synthetic resin are lightweight, and the high-speed opening movement speed of the healds for ear thread 17, 18, 21 and 22 is not impaired. (1-3) Each of the path stabilizing plates 25 and 26 is a pair of thread 2
8, 29 and the thread 32, 33.
The hanging positions of the passing yarns 28 and 29 are just above the healds 17 and 21 for the ear thread, and the hanging positions of the passing yarns 32 and 33 are the healds 1 for the ear thread.
Immediately above 8,22. The suspended state of the thread 28, 29 passing through the eye panel 16 in a parallel state from the thread holes 252, 252 at the suspended position prevents the path stabilizing plate 25 from rotating around the vertical line. And the first twine forming mechanism 20
Overall twisting is prevented. Similarly, thread holes 262, 26
2, the thread passing through the eye plate 16 in a parallel state from the eye 32,
The suspension state by 33 prevents the path stabilizing plate 26 from rotating around the vertical line, and prevents the entire second ear formation mechanism 24 from being twisted. (1-4) The state of the insertion of the ear thread E1 into the thread hole 193 of the semi-heald 19 and the state of the insertion of the ear thread E3 into the thread hole 233 of the semi-heald 23 are plane-symmetrical with respect to the left and right in the thread direction of the warp. is there. Also, the ear thread E2 for the twine ear forming mechanism 20
And the ear thread E4 with respect to the twine ear forming mechanism 24.
Is in a plane-symmetric relationship with respect to the left and right in the yarn direction of the warp. In such a state of insertion symmetry, the tension of the ear thread E1 twists the entanglement ear forming mechanism 20 and the action of the ear thread E2.
The action of twisting the entanglement ear forming mechanism 24 is in a direction opposite to the action of twisting the ear forming mechanism 24. Therefore, the ear thread E1, E2 and the ear thread E3, E
4 and the symmetrical state of insertion with the entanglement ear forming mechanisms 20 and 2

In this embodiment, the first path stabilizer 3
The fitted state of 7 and the second path stabilizing plate 38 prevents rotation of the entire path stabilizing plates 37 and 38 around the vertical line. The rotation of the entire path stabilizing plates 37, 38 around the vertical line is prevented by the semi-healds 19, 2 from the ear thread healds 17, 18, 21, 22.
3 contributes to prevention of detachment.
