An auxiliary presser foot device 8 is mounted near the needle bar 20 of the sewing machine 1. The auxiliary presser foot device 8 includes an auxiliary presser foot part 30, and the auxiliary presser foot part 30 has an opening in which the needle 21 is movable up and down (fig. 8).

The auxiliary presser foot part 30 can be moved up and down by a drive source such as an air cylinder, and if the operator depresses the third pedal switch, the air cylinder operates to lower the auxiliary presser foot part 30, and presses the rail-shaped presser foot support part 19c of the pocket upper mold 19, and the pocket cloth is pressed by the pocket upper mold 19 which is elastically deformed downward (fig. 16 and 17).

The sewing by the sewing machine 1 having the pocket folding device of the above-described configuration will be described.

First, the operator engages the cartridge fixing pin 12 of the cartridge 7 with the cartridge fixing portion 4 on the upper surface of the auxiliary table 9 to fix the cartridge 7 on the auxiliary table 9. At this time, the cartridge lower plate 10 and the cartridge upper plate 16 of the cartridge 7 are opened (fig. 4).

Then, the worker places the body cloth 5 on the lower case panel 10 side and the pocket cloth 6 on the upper case panel 16 side (fig. 9).

Next, the worker slides the template 13 to move forward, and rotates the template 13 around the hinge 15 to place the template 13 on the pocket fabric 6 (fig. 11).

Then, while pressing the pocket fabric 6 from above by the stencil 13, the right slider 18 is moved forward toward the stencil 13, and the pocket fabric 6 is folded along the stencil 13 (fig. 12). Thereby, the right side of the hem 6a of the pocket fabric is formed.

While pressing the pocket fabric 6 from above with the stencil 13, the left slider 22 is moved forward toward the stencil 13, and the pocket fabric 6 is folded along the stencil 13 (fig. 13). Thereby, the left half of the hem 6a of the pocket fabric is formed.

Next, the operator rotates the box upper plate 16 about the hinge 14, superimposes the box upper plate 16 on the box lower plate 10, and sets the box 7 in a closed state (fig. 14). At this time, the body fabric 5 and the pocket fabric 6 are sandwiched between the pocket upper 19 and the pocket lower 23.

Then, the operator moves the left slider 22 in the direction away from the template 13. Then, the operator moves the right slider 18 in the direction away from the template 13. Then, the worker slides the template 13 in a direction away from the pocket fabric 6 to perform the retreat movement (fig. 15).

Next, the operator releases the fixation of the cartridge 7 on the auxiliary table 9, and moves the cartridge 7 to the sewing table 11 on the front side.

Then, the worker inserts the fixing pin 12 of the cartridge 7 into the positioning groove 28 of the cartridge chucking device 2 on the sewing table 11 (fig. 6).

Then, if the operator steps on the first pedal switch, the cylinder of the cartridge chucking device 2 is operated to close the cartridge chucking plate 27. The cartridge retaining pin 12 is retained in the detent 28 (fig. 16).

Next, if the operator depresses the second pedal switch, the cylinder of the cartridge pressing device 3 operates to lower the cartridge pressing frame 29, and the cartridge 7 is pressed from above (fig. 16 and 17).

Next, if the operator steps on the third pedal switch, after the cassette 7 is moved to the sewing start position, the cylinder of the auxiliary presser foot device 8 is operated to lower the auxiliary presser foot part 30, and pocket sewing is performed in accordance with the sewing pattern while pressing the rail-shaped presser foot support part 19c of the pocket upper mold 19.

At this time, since the cut 19b is formed in the pocket upper 19, the pocket upper 19 is elastically deformed from the cut 19b and can be pressed toward the pocket fabric 6 (fig. 18).

When sewing is completed, the air cylinder of the auxiliary presser foot device 8 is operated to raise the auxiliary presser foot part 30. Then, the cylinder of the cartridge pressing device 3 is operated, and the cartridge pressing frame 29 is raised. Then, the cylinder of the cartridge chucking device 2 is operated to open the cartridge chucking plate 27, thereby releasing the fixing of the cartridge 7.

The operator rotates the box upper plate 16 about the hinge 14 of the box 7 to open the box 7, and takes out the body fabric 5 after completion of pocket sewing, and finishes 1 cycle of sewing operation.

As described above, according to the pocket folding device and the sewing machine including the pocket folding device of the above embodiment, the hem 6a of the pocket fabric can be easily folded by merely providing the pocket fabric 6 and the body fabric 5 in the case 7, and the pocket fabric 6 can be accurately positioned on the body fabric 5. This makes it possible to omit the operation of ironing the folded-in pocket fabric by the iron and the operation of accurately positioning the pocket fabric 6 on the body fabric 5, thereby shortening the sewing operation time.

Further, since the operation of folding in the hem 6a of the pocket fabric by the box 7 can be performed on both the left and right auxiliary tables 9, the operation of folding in the hem 6a of the pocket fabric for the next sewing can be performed on the free auxiliary table 9 while performing the pocket sewing by the sewing machine 1, and therefore, the operation time can be further shortened.

In the case where it is desired to sew the pocket fabric 6 so as to have a bulge with respect to the body fabric 5, a U-shaped clip portion 19d (see fig. 10) formed at the center of the pocket upper 19 may be used.

When the worker places the pocket fabric on the box upper plate 16, the worker places the pocket fabric in a state where the holding portion 19d of the pocket upper mold 19 holds the pocket fabric (fig. 10).

This forms a bulge 6b (see fig. 6) of the pocket fabric, and if pocket sewing is performed in this state, the pocket fabric 6 can be sewn to have a bulge with respect to the body fabric 5. In addition, both a pocket with a bulged type and a pocket without bulge can be dealt with without replacing the pocket upper 19.

When the size of the pocket is changed, it is possible to cope with this by replacing only 5 points of the pocket upper mold 19, the pocket lower mold 23, the template 13, the right slider 18, and the left slider 22, and thus it is possible to reduce the cost such as the equipment investment (fig. 5).
