Description

[Detailed description of the invention] Depending on the type of twist of the selvedge yarn used in the planetary gear type J1-assembling device of the shuttleless loom, S-twist and 2-twist are fired when unwinding from a Japanese bobbin. The best way to make the selvedge strong is to choose the most suitable one between heating and unheating, but this invention allows you to easily select the three types of twists, and also change the number of twists. This is a mechanism that makes it possible.

It rotates the bobbin holding part for the selvage thread independently of the yarn guide that opens 1-1 [Fl], and also causes the bobbin holding part rotation drive part for the 11th thread to move to the start/reverse position and to stop the drive. 41.1r(P(.

This relates to a single-thread heating mechanism in a planetary gear type selvedge assembly.

In the past, this ↑ "a planetary key \" method + 4-pol
In the installation, the yarn guide (1)' is moved up and down on a substantially straight line, as shown in Figure 1 a% e.
, itj While the IJ rotary disk (2) rotates once, the old thread bobbin is attached to the shedding rotary disk (2) and the gear (
3↓(3)' rotates twice. In such a device, 1) In a system in which the dowel bobbin rotates together with the yarn guide, one rotation of the shedding rotary disk always applies one twist to the selvage yarn, and the twist direction is the same as the yarn guide. It depends on the direction of rotational force of the rotary disk for 1. +7
Therefore, this method has the drawback that the direction of twisting can be changed by changing the direction of rotation of the opening rotary disk.

2) The bobbin holding part for the thread is opened [fixed to the rotary disk] 1. In this method, the IJ thread itself is not twisted because the moon-type bobbin does not rotate even after an opening rotation of 1 ij or i. Therefore, if the Fl- system itself is subjected to an additional amount of stress, or if 3g is not applied, the ears will not be formed satisfactorily.

The purpose of this invention is as follows: (1) By making the natural direction of force 1 of the selvage yarn free (C cutting L can be done), Ir, 1 'J: 7- L's

By adding 111 hours, if there is already one part in the old thread, it will not be too busy, and the twisting of the thread will reduce the torque.

To explain the mechanism of this invention in detail, Fig. 2 shows Part 1, in which an opening rotary disc 2) equipped with a gear E according to the Group 1 rule is attached to the identification bin P so as to be able to move together. , this gear E is connected to a J-joint type J1 by an X moving gear J).

In addition, the circumferential length of the elongated hole cil, (] Depending on the dimensions, it can also be used as a twisting direction changing mechanism.

This invention has the following effects due to the configuration and operation as described below. First, since the twisting direction and number of twists can be arbitrarily selected, the conditions for the number of binding threads on both sides of the cloth can be made the same, and both ends will be of the same quality. The quality of both the left and right parts is the same, making it possible to produce high-quality IJ. It can also be heated as needed, so it is especially useful when using cotton thread for the selvedge thread (
(required for cotton fabric), strong selvage yarn can be obtained and a firm selvage can be made.
