Description

[Detailed description of the invention] The present invention relates to a new selvedge device, and its purpose is to make it possible to compose selvedges for both the upper and lower fabrics when weaving double velvet etc. with a rapier loom. be.

Weaving double velvet on a rapier loom provides very high productivity, and recently attempts have been made to modify the rapier loom for double velvet. One part of the modification is the selvedge device, and the development (modification) of the selvedge device for both upper and lower fabrics is also an essential theme. The present inventor has completed a selving device for double velvet by modifying a conventional selving device for high-speed planes made of single-ply fabric. Therefore, the configuration of the ear-squeezing device for double velvet according to the present invention will be explained.

Figure 1, Figure 2, Figure 3, and Figure 4 are diagrams showing the principle of the high-speed ear straining device to which the present invention is applied.
The figure is a front view of the rolling plate, with an oblique elongated hole 1a extending downward to the left above the front plate 1, and an elongated oblique hole 1b extending downward to the right below. Further, in the rear plate 2, at positions corresponding to the oblique holes 1a and 1b of the front plate 1, there are provided oblique holes 2a and 2b, respectively, which go downward to the right, and downward to the left. Fig. 2 is a front view of these folding plates superimposed, and A shows that when the front plate 1 is slightly shifted upward, the curling threads 3 passed through the diagonal slots 1a and 2a move to the left, and the threads 3 passed through the diagonal slots 2b , 1b
moves to the right. B shows the case where the rear plate 2 is moved upward, and contrary to A, the winding thread 3 is on the right, and the winding thread 4 is on the right side.
moves to the left. Fig. 3A shows the ground warp 5 at the lower tip of the ground warp hook 6 combined with the rolling plate of Fig. 2A, and when the rolling plates (front plate 1, rear plate 2) are pushed up as shown in B, the ground warp 5 is There is a thread 3 on the left and a thread 4 on the right, and if the weft threads 7a are woven in this state, a state C is woven. Also, in Fig. 4, Fig. 2 B and hook 6
With the structure shown in FIG. 1, the drawing thread 3 is moved to the right of the ground warp thread 5, the drawing thread 4 is moved to the left, and when the threads A, B, and weft thread 7b are knitted, it becomes as shown in C. By repeating the steps in Figures 3 and 4 alternately, two sets of both sides are woven, but in this invention, we have created a device in which two sets of both lines are woven on the upper ear and two sets on the lower ear. . Figure 5 shows its structure.

FIG. 5 is a front view A and a side view B of the device for both upper and lower ears according to the present invention. 8 is a hook plate for the ground warp, and in the center there are short hooks 8a, 8b for the ground warp for the upper selvage.
, and on both sides there are long hooks 8 for the lower selvedge warp threads.
c and 8d are arranged in a comb-like manner with the tips facing downward and fixed to the block 11. The front plate 12 and the rear plate 13 of the swing plate are assembled below the hook plate 8 so that the rear side of the hook plate 8 can be raised and lowered up and down close to each other.
a, and the lower part of the rear plate 13 is attached to the rear slider 13.
It sticks to a. At the upper center of the front plate 12 is a hook 8.
Oblique oblique holes 14a and 15a for upper selvedge warp threads (downward to the left) are lined up corresponding to points a and 8b, and similar oblique long holes (downward to the right) 14b and 15b are provided below. On both lower sides of the front plate 12 corresponding to the hooks 8c and 8d are oblique oblong holes (downward left) 16 for lower selvedge warp threads.
a, 17a and a similar oblique hole below it (downward to the right)
16b and 17b are provided. Each oblique slot 1 in the front plate 12
4a, 15a, 14b, 15b, 16a, 17
Opposite downward oblique oblong holes 14c, 15c, 14d, 15 at positions corresponding to a, 16b, 17b, respectively.
d, 16c, 17c, 16d, and 17d are provided.
When the front lifting block 18a is pulled up, the lower block 18c is pulled up by the shaft 18b,
The front slider 12a front plate 12 is slightly raised as shown in Figure 2A.
The warp threads are divided to the right and left and move as shown in the figure. When the front slider 12a is pulled up further, the protrusion 12b of the front slider 12a engages with the lower piece 13b of the rear slider 13a and is pushed up (pulled up), causing the front plate 12 and the rear plate 13 to be in the state shown in FIG. 3B, and when the weft is inserted. Third
You can create the strained tissue shown in Figure C. When the front block 18a is lowered and the rear lifting block 19a is pulled up, the lower block 19c first pushes up the rear slider 13a a little by means of the shaft 19b, so that the rear plate 13 rises above the front plate 12 as shown in FIGS. 2B and 4. Since the situation is as shown in Figure A, the left and right positions of each of the drawn warp threads are switched. When the rear slider 13a is further pulled up, the upper piece 13c of the rear slider 13a becomes the upper piece 12 of the front slider 12a.
c, the front and rear sliders 12a and 13a rise together, and the front plate 12 and rear plate 13 become in the state shown in FIG. 4B. If the weft is inserted here, the structure shown in FIG. 4C will be obtained. In this way, two sets of double folding structures are formed on each side of the upper and lower fabrics, so that the selvedge structure becomes stiff.

Fig. 6 is a side view of weaving an selvedge using the inventive knitting device shown in Fig. 5, where A is when the front block 18a in Fig. 5 is pulled up, and B is when the rear block 18a in Fig. 5 is woven.
This is the case when 9a is pulled up. 21 and 22 are the upper ear draw warp, 23 are the upper ear ground warp, 24 and 25 are the lower ear draw warp, and 26 are the lower ear ground warp. 8b is a hook for the upper selvage warp (for 23), 9b is its thread passing hole, 10b is its guiding guide, 8d is a hook for the lower selving warp 26, 9d is its threading hole, and 10d is its guiding guide. . 12 is the front plate of the tsuki board and 13
is the back plate. 27, 28, 29, 30, 3
1 is an upper weft, 32, 33, 34, 35, and 36 are lower wefts, and 37 is a reed. C is D when the upper ear is strained.
is a condition of lower ears.
