記の技術を先に提案した(昭和63年実用新案出願公告
第45260号公報)。However, in recent years, there has been a demand for a soft and heavy-feeling cloth having a large elasticity and a large thickness.
In the case of using such an easily stretchable and heavy cloth, the teeth 28a, 24b,.
It is difficult to pull out the cloth 28a by the teeth 25a of the auxiliary feeding means 25.
It is difficult to extrude to the vicinity below. As a result, the feed amount of the cloth 28a tends to be smaller than the feed amount of the tape 29, and it is difficult to reliably perform the flat stitch. The relative stroke L 1 of the main feed unit 24, the auxiliary feeding means 2
When 5 of the stroke L 2 is set to be longer with this problem to some extent it may correspond, but since the operating time proportional to the length of stroke L 2 becomes longer, the production efficiency is lowered. In order to address these problems, the present inventors have previously proposed the following technology (Japanese Utility Model Application Publication No. 45260 in 1988).

易いという課題があった。In the above-described cloth edge tape winding machine 20, the number of teeth 25a in the auxiliary feeding means 25 is limited due to the structural limitation of winding the tape 29 around the outer edge of the cloth 28a. Since it has to be reduced to about one row, it is difficult to push the cloth 28a having large elasticity and heavy weight to the vicinity below the needle 23. As a result, the feed amount of the cloth 28a tends to be smaller than the feed amount of the tape 29 as described above, and it is difficult to reliably perform the flat stitch. The relative stroke L 1 of the main feed unit 24, while a certain extent this problem by setting a longer stroke L 2 of the auxiliary feed means 25 may address, time operation in proportion to the length of stroke L 2 is longer Therefore, there has been a problem that the production efficiency is easily lowered.

課題があった。Further, in the above-mentioned cloth edge tape winding machine 30, since the auxiliary feeding means 35 is formed with the teeth 35a and the claws 35c, the cloth 28a having large elasticity and heavy weight is provided.
However, compared to the case of the winding machine 20, the cloth 28a can be pushed out to a position near the lower side of the needle 23. However, the cloth feed claw 35 attached to the mounting table 26b
Since b is driven in an elliptical orbit as shown by the arrow D in FIG. 5, driving the claw 35c of the cloth feeding claw portion 35b so close to the needle hole 22e that the needle plate 22 becomes an obstacle. Was difficult. Therefore the elasticity is even greater,
In the case of a heavier cloth, even if the cloth 28a is once pushed out to the vicinity below the needle 23, when the auxiliary feeding means 35 retreats, the rear part of the pushed-out cloth 28a easily moves backward. There was a possibility that the same problem as that described above might occur. In the winding machines 20 and 30, the teeth 25a and 35
There is a problem that formation of a and the like is troublesome, and the cost is high and the cost is easily increased.

Even when a cloth having a greater elasticity and a heavier weight is used, a tape is wrapped around the outer edge of the cloth and the knitted flat stitch is used. An object of the present invention is to provide a cloth edge tape winding machine that can perform sewing reliably and efficiently and that is inexpensive to manufacture.

In a cloth edge tape winding machine having main feeding means for feeding a sewn sewn cloth forward from the needle, a feed claw formed with a plurality of claws into which the bite is inserted and the needle is inserted. The auxiliary feeding means is configured to include a part, the feeding claw part is driven in parallel to the upper surface of the needle plate, and the needle descends at the timing when the feeding claw part sends the cloth and the tape forward, The needle is controlled so as to perform a sewing process at a timing when the feed claw portion is retracted.

When the feeding claw portion formed on the auxiliary feeding means is driven forward, the plurality of claws bite into the cloth, and the cloth can be reliably sent to a predetermined position in front of the needle. . Also at that timing, the mechanically controlled needle descends and penetrates the cloth and tape,
These can be reliably held at the predetermined position.
Further, since the feed claw portion is driven in parallel with the upper surface of the needle plate, the claw can be pulled out of the cloth without being interfered by the needle plate, and can be smoothly retracted. The tape can be reliably sewn to the cloth. As a result, the elasticity is even greater,
Even if a heavier cloth is used, the stitches can be reliably and efficiently sewn with the flat stitches, and the teeth provided in the conventional auxiliary feed means are omitted.
Manufacturing costs can be reduced.

The needle can be advanced to the upper surface of the needle plate 22, and the feeding claw 15a formed on the auxiliary feeding means 15 moves forward (A
When driven in the direction, the plurality of claws 15b bite into the cloth 28a, and the cloth 28a can be reliably sent to a predetermined position in front of the needle 23. At that timing, the mechanically controlled needle 23 descends, and the cloth 28a and the tape 2
9 can be securely held in place. Further, since the feed claw portion 15a is driven in parallel to the upper surface of the needle plate 12, the claw 15b can be pulled out from the cloth 28a without being interfered by the needle plate 12, and can be smoothly retracted in the B direction. At that time the cloth 28a
The tape 29 can be reliably sewn to the tape. As a result, even when the cloth 28a having a greater elasticity and a larger weight is used, the stitch can be reliably and efficiently sewn by the flat stitch 28b, and the conventional auxiliary feeding means 25, The tooth part 25a provided on the 35,
35a can be omitted, and the manufacturing cost can be reduced.
