It is also possible to print the outer surface parts Aa to Ah in a designated pattern and color and cut them, and the required size of the sewn product B is shorter and the yield is larger than in the case of cutting into the pattern shown in FIG. Thus, the sewing object B can be used effectively and economically.
[0048]
Next, as shown in FIG. 9, the outer and interlining parts Aa to Ah pressed and held by the belts 48a, 48b and 48c constituting the conveyor 48 are heated by the heater 49 of the thermocompression bonding apparatus 47. After being integrally bonded and fixed, they are housed in the parts housing part 50 while being vertically overlapped. In substantially the same manner as described above, the lining sewing material B that has passed through the steps a, b, and c is cut into a size and a pattern corresponding to the lining parts Aa to Ah of the sewing material A, and After being superposed on the upper side in correspondence with the stored outer and interlining parts Aa to Ah, the outer and interlining and lining parts Aa to Ah constituting the sewn product A for one piece are superimposed vertically. It is stored in the parts storage 50 as it is and supplied to a sewing process (not shown).
[0049]
As described above, based on the cutting data stored in the information management device 3, the sheet-shaped sewing material B is cut into the interlining material, the outer material, and the lining parts Aa to Ah by the sewing material cutting device 35. The interleaved interlining parts Aa to Ah previously held by the stacking device 42 are held by the stacking device 42, and the next to-be-sewn object B and the outer material parts Aa to Ah are once raised to a height where they can be transported, and then cut again. Since the upper and lower parts of the outer material parts Aa to Ah are moved and corrected to the position substantially opposed to the interlining part and superimposed on the upper side, the pattern dyed and embroidered on the parts Aa to Ah as in the conventional example at the time of sewing. There is no need to cut the parts so that they coincide with each other, and the parts Aa to Ah of the interlining, the outer material, and the lining can be arranged in any direction and at an interval and cut. In addition, the loss and waste of the sewing object B generated at the time of cutting are reduced, the sewing object B can be used effectively and economically, and the required length of the sewing object B required for cutting can be shortened, Since the yield is increased, the sewing cost can be reduced.

FIG. 10 shows another embodiment of the sewing product cutting device 35 in which the embroidery device 52 is disposed after the finishing process b (for example, between the dewatering process c and the cutting process d). The embroidery unit 53 of the embroidery device 52 constituted by a sewing machine or the like is driven and moved based on the embroidery pattern stored in the information management device 3, and the embroidery unit 53 of the sewing object B sucked and held on the transport conveyor 39 is moved. After the pattern is embroidered on the designated portion with the embroidery thread of the designated color, it is cut by the cutting unit 36 into the size and the pattern corresponding to the outer and lining parts Aa to Ah constituting the sewing product A. Functions and effects substantially equivalent to those of the example can be obtained.
