Automatic sewing machine for sewing twin seams in workpiece, has guiding body guided into guiding link for generating two seams in two guiding in respective guiding positions, where one of distances is larger than other distance

The machine (1) has a workpiece transport device for transporting a workpiece (2) during sewing, and a seam guiding device with a guiding body guided to a guiding link for presetting a weld shape. One of the link and body is rigidly connected to a workpiece supporting plate (3), and the other is rigidly connected to the transport device. The body is traversely displaced between two guiding positions, and is guided into the link for generating two seams in two guiding distances in respective positions, where one of the distances is larger than the other distance.

AUTOMATIC SEWING MACHINE

PROBLEM TO BE SOLVED: To provide an automatic sewing machine, maintaining high process stability, and also sewing various pairs of materials to be sewn at a high process rate. SOLUTION: This automatic sewing machine, which automatically sews two materials to be sewn, includes a sewn material support part, an insertion and preparation station, a sewing station, and a stacking station. A first conveying unit fulfills a function of fastening two materials to be sewn located in the relative sewing positions, moving them from the preparation station to the sewing station at a conveying speed, and moving the materials to be sewn at a sewing speed in the sewing process. A second conveying unit fulfills a function of moving two materials to be sewn from the sewing station to the stacking station at another conveying speed. A driving motor is used for moving a conveying sub-unit of the first conveying unit for maintaining the relative sewing positions when two material to be sewn are moved by the ...

Sewing machine and feed station for such a sewing machine

AUTOMATIC SEWING ASSEMBLY AND FEED STATION FOR SUCH AUTOMATIC SEWING ASSEMBLY

PROBLEM TO BE SOLVED: To increase flexibility for various pocket sizes of an automatic sewing assembly. SOLUTION: The automatic sewing assembly has a sewing station having a sewing machine for sewing material pieces (4, 5) which are placed one on top of the other, a support plate (9) for the material pieces (4, 5) and a feeding station (6). The feeding station (6) serves to feed/prepare the material pieces (4, 5) and is arranged upstream of the sewing station. The feeding station (6) has a positioning stopper (7) for setting a defined relative position of the two material pieces (4, 5) relative to the support plate (9).
