BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suturing device used for rejoining a woolen fabric, for example.

[0002]

2. Description of the Related Art Woven fabrics woven in the weaving process are wound up into lots and made into fabrics of a predetermined length. It enables continuous processing. The jointing of the piece of fabric (referred to as “rejoining”) is performed manually by using an automatic traveling end stitch sewing machine installed along the transport path of the fabric while supplying the fabric to the processing machine. That is, when the remaining amount of the cloth of the piece of cloth currently being supplied to the processing machine becomes small, the worker stands by in front of the sewing machine, and when the switching portion of the piece of cloth passes by the sewing machine, the end of the preceding piece of cloth and the next piece of cloth are passed. The starting end of the sewing machine is pulled up to the sewing position of the sewing machine, and the sewing machine sewes both of them together.

[0003]

However, since it is general for an operator to handle a plurality of machines (often two machines) by himself, if the timings for switching the cloths overlap, One of the machines had to be stopped, which was an obstacle to improving the operating rate. Further, since the work is performed while the cloth is being transferred, a stitching error is likely to occur, which adversely affects the finish of processing. Therefore, it has been a problem to automate the anti-splice and improve the operation rate and the quality.

[0004]

In order to solve the above-mentioned problems, the present invention has the following constitution. That is, the suturing device according to the present invention includes a support means for supporting the winding body of the first cloth at a predetermined position, a transfer means for horizontally transferring the first cloth pulled out from the winding body, and a first means. Detecting means for detecting that all the cloth has been pulled out from the winding body, a holding means for holding the winding body of the second cloth above the transfer path of the first cloth, and a starting end of the second cloth. The cloth edge hanging means capable of hanging the portion downward by a predetermined length, the sewing machine provided below the transfer path of the first cloth, and the detecting means using the first cloth from the winding body. When it is detected that the cloth has been pulled out, the transfer means is stopped so that the end portion of the first cloth is hung on the sewing portion of the sewing machine, and the cloth end hanging means is operated to move the start end portion of the second cloth to the sewing machine. It has a control device for controlling so as to guide it to the sutured part of the It is set to.

[0005]

When the detection means detects that the first cloth has been completely pulled out from the winding body, the transfer means is stopped and the end portion of the cloth wound around the first cloth winding body is sewn by its own weight. And supply it to the second part by the cloth edge hanging means.
The cloth is pulled out from the winding body downward by a predetermined length and the starting end of the second cloth is supplied to the sewing portion, and the sewing machine sews the ending end and the starting end of both cloths.
