Apush-up lever (1) is rotatably supported on a sewing machine frame, and a coupling lever (8,9) is coupled to the push-up lever (1). An oscillating shaft (3) is rotatably supported on a bush (10), and the coupling lever (8,9) is engaged with a part of the oscillating shaft. A presser base (4) is coupled to a crank piece (12) of the oscillating shaft (3), and a presser foot (4a) is fixed at its leading end. An elastic member (5) engaged with the presser base (4). A bracket (11) changeable in fixing position is supported on the back side of the sewing machine frame, and the bush (10) is fixed in the bracket. The crank piece (12) of the oscillating shaft (3) is separable in two pieces, and the engaging faces of the two separated crank pieces (30, 31) are fixed anew when changing the fixing position of the bracket (11). Therefore, the circular track of the presser foot (4a) near the platform (BS) of the sewing machine bed can be changed easily, and an eccentric portion (31b) of the crank piece (31) is not changed from an initial setting position.

Waist part cloth guiding device for a sewing machine comprises a guide which folds and guides a side end portion of a cylindrical cloth to enclose a ring band before the needle drop point, while feeding the band together with the cloth in a cloth feed direction by a forced feeding device, regardless of the operation of a main shaft of the sewing machine. After setting the ring band to be inserted into the folded portion of the cylindrical cloth at a position close to needle drop point of the sewing machine, the side end portion of the cylindrical cloth may be automatically guided and folded to the lower side of the ring band.

The automatic sewing apparatus for hemming and closing sleeve of the invention is used for making a tubular sleeve in a short-sleeved T-shirt, and after putting the sleeve blanks on a conveyor only, the subsequent operation is done fully automatically and continuously to make tubular sleeves, so that saving of labor, enhancement of productivity, and reduction of production cost may be realized. In particularly two types of shape cut for sleeves can be sewn by using the apparatus by turning them in adequate direction. The apparatus comprising of a first sewing machine 2 for hemming and second sewing machine 3 for edge sewing disposed at both inner corner sides of an L-shaped sewing table 1, a blank feed device 4 nstalled, at the table part 1A of the first sewing machine 2 side, a folding member 5 of the blank edge, a hemmed piece deflecting device 12, and direction turning members 30, 35 for turning the deflected piece.
摘要:
The automatic sewing apparatus for hemming and closing sleeve of the invention is used for hemming a sleeve blank as for short-sleeved T-shirt, and sewing in a tubular form, and only after putting the sleeve blank on a conveyor, the subsequent process is done fully automatically and continuously to make a tubular sleeve, and hemmed piece deflecting function is done securely and satisfactorily. The apparatus composed of the first and second sewing machines 2, 3 disposed at the inner corner sides of the L-shaped sewing table 1, a feed device 4 having a conveying surface disposed on the table part 1A of the first sewing machine 2 side, a folding member 5 for folding the blank edge along the feed direction, a deflecting device 12 having a member for stopping the running of the front end of the hemmed piece above the conveying surface, and a transfer device 24 for feeding the deflected piece W2 to the second sewing machine 3.
