It is possible to rotate the rotation. Further, the guide claws 45, 413° 47 are arranged with different angles in sequence, and the tip of the rlr receiver has a structure in which the curvature of the ten claws becomes smaller as it goes toward the mechanism 17 side. .

The female mechanism 60 built into the sewing machine main body 4 is designed to simultaneously cut the sewn threads and threads on the sewing thread. Therefore, the details will be omitted.

Next, the operation of the automatic sewing machine having such a configuration will be explained.

First, as shown in FIG. 9, the hanging rollers 12, 13, 14 of the rubber body automatic winding device 2t10 and the rubber receiver of the rubber guide mechanism 16 are placed astride the stand 28, and the annular rubber rest 70 is hung 1].
- Then, a ring-shaped /p71, which is the waist circumference of pants or the like, is hung 11 so as to surround the annular rubber body 70. At the time of this hanging 11, the end edge 71a of the annular 4j is hung with a predetermined width necessary for wrapping the annular rubber body.
Hang it 11- so that it hangs even more.

If the rubber body automatic winding device 2ito is turned on in this state, the rotating roller 26 of the traveling mechanism 15 starts to rotate, and at the same time, the cylinder 24 of the traveling mechanism 15 operates, and the annular /Ij? + becomes tense and the rear hook 11-roller 12 rolls into contact with the rotating roller 2B,
The annular Go 1, the body 70, and the annular In71 begin to rotate integrally.

By the way, just before the annular rubber body 70 and the annular cloth 71 begin to turn, the cloth receiving mechanism 17 and the winding mechanism 18 are in positions facing and separated from one end edge of the annular cloth 71 where the annular cloth 71 is drooped. At this time, the cloth receiver mechanism 17 is in the 41 guide 40 of the mechanism 17 in the fully moving state.

Then, when the annular rubber body 70 and the annular cloth 71 turn, as shown in FIG. 10, the cloth receiver mechanism 17 and the winding mechanism 18 are connected to one end edge of the annular A17t. With this movement, the cloth holder moves the holder 62 towards the rubber guide mechanism 1.
The rubber receiver 6 is placed on the F side of the stand 28, and
- Move the cloth guide 40 on the side (Fig. 11), and move the guide claws 45, 48, and 47 of the winding mechanism 18 sequentially from the rear side to the end edge of the annular cloth 71. 1a is rolled up and guided by the annular goto body 70 (FIG. 12), and the cloth receiver is maintained in a secure rolled-up state via the holder 62 to form the rubber-wrapped portion 73. By the way, the wrapped state is as follows.
In addition to the winding mechanism 18, this mechanism can be used alone, that is, the holder 41 can be used without the halter 62. This is because the guide claws 45, 48, 47 are arranged along the running direction of the annular/1i71, and the guide claws 45, 48, 47 are arranged along the running direction of the annular/1i71. This is because the cloth edge 71a 17 is designed to overcome the tension that tends to cause the cloth 1a to warp to its original sagging state, and the cloth end edge 71a 17 is always guided in the winding direction.

This winding is completed by rotating the rotary opening/roller 26 for a set time and then stopping it.

The order of operations for wrapping the annular rubber body 70 around the annular body 4171 is not limited to the above description.
The lowered edge of the annular/l]71 that is hooked to the traveling mechanism 15? 1a, and the cloth holder is the holder 6 of the mechanism 17.
2 and the respective guide claws 45, 46, 47 of the winding mechanism 18 are moved forward to wind it around the annular rubber body 70; After that, even if the annular rubber body 70 and the annular cloth 71 are rotated in this state, the end edge of the annular 4] 71 will remain in the same manner as described above. 1a can be wrapped around the annular rubber body 70.

When the rotating roller 26 stops, the presser foot 63 and forced feed roller 64 of the sewing machine main body 4 move upward, and the sewing receiver enters the sewing state.

Then, the station 7 moves to the side of the sewing machine main body 4, guides and stops the rubber-wrapped portion 73 to the sewing machine needle as shown in FIG. The sewing machine main body 4 is driven in accordance with the downward movement, and the rubber-wrapped portion 73 is sewn.When the rubber-wrapped portion 73 is sewn with a predetermined length left, the sewing machine body 4 is moved at a predetermined position of the traveling mechanism 15. A microswitch (not shown) is designed to detect the sewing part, and by this detection, the rubber receiver that is an obstacle to sewing is removed from the stand 28, and the cloth guide 40 of the body holder 82 and the winding mechanism 18 are removed. The guide claws 45, 48, and 47 are moved downward to separate them from the unsewn portion. Note that when the cloth guide 40 moves downward, if the rubber receiver leaves the stand 28 in the same state, the rubber receiver will come into contact with the curved part 28a of the stand 28, so at this time, the rubber receiver will tilt the stand 28. The cloth guide 40 is designed so as not to interfere with detachment.

When the microswitch detects this, the set needle movement counter operates, and when the number of stitches covered by the counter has been sewn, the tension around the loop of the traveling mechanism 15 is released, and the sewing machine main body 4 side also stops driving. The L thread and the bobbin thread are cut simultaneously by the female mechanism 80. After this cutting, the presser foot 63 of the sewing machine main body 4 and the forced feed roller 6
4 moves upward, and the station 7 separates from the sewing machine main body 4 and returns to its original position.

At the time of this return, the rubber receiver base 28 returns to its original state, and the movable base 26 also returns to its original position, making it ready to hang the next hanging object.

By the way, is there one station in the other station 7? The item to be sewn above 70.71 is M! While this is being done, the rubber-wrapped workpieces 70 and 71 are kept waiting, and when the sewing of the workpieces 70 and 71 at one station 7 is completed, the sewing machine body 4 is placed on the base! - move the
Stop at this other station 7 position, sew the &l wisdom object 70.71 on this station 7 in the same manner as described above, and then move to the first station 7 while this station 7 is engaged in sewing. The sewing machine main body 4 is alternately sewn at each station 7.7 so that the rubber-wrapped stretched sewn product is kept waiting.

With such a configuration, the annular rubber body 70 can be automatically wrapped around the end edge 71a of the annular cloth 71, and the rubber-wrapped portion 73 in this wrapped state can be guided to the needle drop part of the sewing machine body. Automatic sewing can be performed from the beginning through the sewing process to the completion of sewing by cutting the sewing thread by the female mechanism 60 of the sewing machine main body 4. In addition, for 41 sewing machine bodies, automatic rubber body winding device @1
Since the configuration includes two sewing machines, one sewing machine can be operated effectively.

Incidentally, the number of rubber body automatic winding devices i10 may be increased in number to the sewing machine main body 4 to increase the operating rate of the sewing machine.

Further, in the above embodiment, the cloth end winding device of the present invention is applied to an automatic rubber body winding device, but the invention is not limited to this, and the present invention device can be applied within a plane including the needle drop of the sewing machine body. It is also possible to equip the machine so that the operator can directly sew the wrapped part.

Furthermore, the present invention may be applied to a fabric in which a plurality of parallel rubber bodies are rolled up at the edge of the cloth instead of the annular rubber body.

Further, the present invention can obtain similar effects even when applied to hem sewing, etc., in which the edge of the cloth is simply rolled up and the rolled up part is sewn.

Furthermore, the present invention is not limited to the above embodiments. For example, as shown in Figure 1 (A), (B), and (C), L-shaped rewinding claws 45a, 48a, and 47a as shown in the figures can be rotated at the tips of each guide claw of the winding mechanism. It is also possible to have a configuration in which the

Further, the present invention is not limited to the rubber-wrapped state of the above-described embodiment, but may also be such that the cloth end edge 71a is wound back inside the annular rubber body 70, as shown in FIG. 17(B).

In this case, the guide claws 45, 48, 47 of the winding mechanism 18
The cloth guide 40 of the mechanism 17 is arranged so as to be rolled up inside the annular rubber body 70, and the cloth guide 40 of the mechanism 17 is arranged so as to be rolled up inside the annular rubber body 70.
, the body should be positioned and the rolled up part should be held.

(Effects of the Invention) As explained above, the cloth edge winding device of the present invention, by running the &j, handles the drooping cloth edge by a plurality of guide pawls arranged along the running direction. , it is possible to form the cloth into a gradually folded state, so if an existing sewing machine is equipped with the device of the present invention, it can be made in one piece! It solves the problem that it requires skill to master [7], and even those who have not mastered this type of sewing work can easily use it immediately, and this type of sewing I: The effect of W'j on the development of
