く、生産効率の向上に役立つ。FIG. 1 is an overall schematic diagram of an automatic machine for carrying out the method of the present invention, and 1.1 shows fabric holders (hereinafter referred to as holders) arranged in parallel, and phantom line A in FIG. As shown, a cylindrical fabric 100 is fitted. The fabric 100 fitted into the holder 1 is kept in its cylindrical shape and is moved by the feeding means 2 provided on the holder 1 to the edge 1 of the fabric.
01 is advanced to a position opposite to the needle dropper 3 of the sewing machine shown in FIG. The feeding means 2 includes a pair of rollers 2
a, 2a, and an endless belt 2b wound around these rollers 2a, 2a, and are provided at a plurality of locations equiangularly spaced around a frame 4 having a truncated conical tip. As clearly shown in FIG.
are synchronously driven to rotate in the same direction. That is, the roller 2a of the feeding means 2 is provided with a helical gear mechanism 6, and this helical gear mechanism 6 is connected to the rotating shaft 5a of the drive source 5.
is connected to via a transmission gear 7. For example, if a stamping motor is used as the drive 'a5,
00 can be quantitatively advanced. Also fabric 10
There is an advantage that the feed position of the fabric edge 101 can be accurately controlled while controlling the tension of the fabric edge 101. Whether or not the fabric 100 has been advanced to the needle drop 3 is detected by fabric edge detection means 8 such as a phototube. That is, the fabric edge detection means 8
The fabric edge detection signal output from the drive source 5 is inputted to the drive source 5, and the rotation of the drive source 5 is stopped. If the plurality of feeding means 2 are simply driven in synchronization so that the fabric edge 101 faces the needle dropper 3, each part of the fabric edge 101 will become uneven in the front-rear direction, as shown by the imaginary lines in FIG. Therefore, when such irregularities occur, the fourth
As shown by arrow A in the figure, the pair of holders 1 and 2 are synchronously rotated in the same direction by a required angle to idle the fabric edge 101. After the fabric edges 101 are aligned in the front-back direction by this idle rotation, the process moves to the tri-folding process. A mechanism for rotating the holding body l is shown in FIG. As is clear from the figure, the holder 1 is provided with a rotating shaft 9, and this rotating shaft 9 is connected to the drive source 1.
0 via a transmission gear mechanism 11, and the rotation shafts 9, 9 of the left and right holding bodies 1.1 are connected to each other by a transmission heald 12. Also, as the holding body 1.1 rotates,
The idle length of the lining edge 101 is accurately detected by a rotation amount detector 13 such as a rotary encoder shown in the figure. Furthermore, in order to smooth out the wrinkles occurring at the edge 101 of the fabric, the suction mechanism 14 utilizing negative pressure shown in FIGS. 4 and 5 is activated. This suction mechanism 14
The support plate 1 is equipped with a support plate 16 that is raised and lowered by an air cylinder 15 and an air nozzle 17 that blows air forward.
6 and the air nozzle 17, negative pressure is generated in front of the fabric edge 101, and the negative pressure effect causes the fabric edge 10 to
1 is suctioned to smooth out wrinkles. If such wrinkle smoothing is performed while the fabric 100 is idly rotated as described above, there is no need to set a special time frame for wrinkle smoothing, which helps improve production efficiency.

を示している。Sewing is performed over the entire length (entire circumference) of the tri-folded portion 103. During this sewing, the hemming ruler 23, the support plate 16 of the suction mechanism 14, and the air nozzle 17 are attached to the tri-folded portion 103 as described above. Since they overlap, they will get in the way of the sewing machine at the final stage of sewing. Therefore, when the sewing machine has finished sewing almost the entire circumference of the trifold portion 103, use the hem ruler 2 as shown by arrow E in FIG.
3 from the trifold portion 103. The suction mechanism 14 is also released from the trifold portion 103 in the same manner. After doing so, continue sewing the unsewn parts shown in the same figure. Further, the starting and ending ends of the sewing are double stitched Ll as shown in FIG. 14 to prevent the threads from fraying. 13th
The figure shows a state in which the feeding means 2 of the holder 1 is operated to release the trifold portion 103 from the needle dropper 3 after sewing has been completed.
