W4 is a hem part, W5 is an open part, and the cutting shape may be arbitrary.

The present invention has the above configuration, and its operation will be explained below.

First, slide member 8 at position L as shown in FIG.
7 reaches the position M and stops due to the drive of the chain 89, and then the cylindrical cut fabric W is cut as appropriate.
The hem W4 of the cloth W is held between the clips 96, 96, and the cloth W is gripped and suspended through the operation of the air cylinders 92, 92.

Then, by operating the air cylinder 100,
The piston 103 and rod 104 are pushed out, and the rods 105, 105 are pushed down, and the rod 10
5, 105 long holes 106, 106 are guides 10
1, 101, further the piston 1
03. When the rod 104 has descended to its full stroke, the rotating pieces 107, 107 are rotated from the vertical to the horizontal position as shown by the dotted line in Fig. 8, and the front and back parts of the fabric W are rotated.
1. Disturbance of W2 is prevented.

Next, as shown in FIG. 9, the slide member 87 further descends through the operation of the chain 89, and the front and rear bodies W
1 and W2 descend from position H to I while the horizontal movement of the fabric is restricted by the rotating pieces 101 and 101, and the slide member 87 reaches position N and is stopped. That is, the front and back pieces W of the fabric are placed between the bars 11 and 12 below the rotating pieces 107 and 107 and waiting at positions X and X.
1, the fabric W descends to position I while being regulated to prevent W2 from entering.

Next, as shown in FIGS. 8 and 9, the rods 75 and 76 at positions A and A are respectively lowered from A and A to positions B and B through the retraction of the piston 66 of the air cylinder 59, and then moved to positions X and X. The bars 11 and 12 located at They are spread on the table surfaces 10 and 27, respectively. Next, the rod 75 at position B,
76 rises and returns to position A,A.

Next, as shown in FIG. 10, the holding pieces 9 and 83 at positions D and D are lowered to positions E and E through the pushing action of the pistons 6 and 82 of the air cylinders 5 and 79, respectively, and the front and rear bodies W1, W2 is pressed, and then as shown in FIGS. 9 and 10, the holding plate 52 rotates and presses the front body W1 through the operation of pushing out the piston 56 of the air cylinder 55, and then the piston 47 of the air cylinder 48 is pressed.
By retraction, the presser plate 52 retreats through the retreat of the slide piece 50, and the front body W1 is stretched from the position S to the position T.

Next, as shown in FIGS. 13 and 14, the clips 22 and 22 in position J are respectively attached to the air cylinder 2.
The clip piece 22b is moved from position J to K through the pushing operation of the piston 28 of the air cylinder 24, and then the clip piece 22b is rotated through the pushing operation of the piston 25 of the air cylinder 24.
1 and 94 respectively grip the cloth W being gripped.

Next, the clip pieces 94, 94 are retracted by the retraction of the piston 95 of the air cylinder 92, the clips 96, 96 are opened, and the grip on the fabric W is released, and the fabric W is held by the clips 22, 22. Then, as shown in FIG. 7, the slide member 87 that was at position N returns to position L, and
Next, the piston 103 of the air cylinder 100
is retracted, and the rotating pieces 107, 107 return from the horizontal state to the vertical state.

Then, through the pushing operation of the piston 41 of the air cylinder 40, the clips 22, 22 are moved from the position K to the position K1 indicated by the dotted line, respectively, as shown in FIG.
At the same time, the rotary air cylinder 34
Through the rotation of the shaft 35, the rod 36 rotates to the position indicated by the dotted line as shown in FIG.
Clip 2 while moving the fabric W to the center using 37.
2 and 22 and reach the dotted line position.

Next, the clips 22, 22 and the plates 37, 37
moves in the direction of the arrows in FIGS. 17-18, ie, to the dotted line position K2 in FIG. 18, through the pushing operation of the piston 33 of the air cylinder 32.

Next, by pushing out the piston 74 of the air cylinder 73, the rod 76 is pressed toward the rod 75, and the dough W is pressed and held as shown in FIG.

Next, the clip pieces 22b, 22b are opened by the retraction of the piston 25 of the air cylinder 24, and the grip of the dough W by the clip 22 is released, and at the same time, the shaft 35 of the rotary air cylinder 34 is opened.
As the rotation returns, the contact plates 37, 37 return to rotation, and then, as the pistons 41, 28, 33 of the air cylinders 40, 29, 32 retract and return, the clip 22 and the contact plate 37 return to their original positions J. It returns and the cylindrical part W3 of the dough W becomes the rods 75 and 76.
The material is gripped by the holder and folded into a half-fold shape as shown in FIG.

Next, a suitable conveying member C is moved in parallel in the direction of the arrow in FIG. 19, and as shown in FIG.
3, and with the presser plate 52 raised and returned to its original position, and the rod 76 released and returned to its original position, the material W is gripped by the conveying member C having the clipping means C1, C2, and C3, and the material W is again moved in parallel in the opposite direction; The fabric W is conveyed and supplied to an appropriate sewing machine process. In the present invention, in the cylindrical fabric that has been appropriately cut as described above, the cut portion is expanded into a bifurcated shape, the cylindrical portion is further narrowed, and the cylindrical portion is folded in half through a bar, and then sent to the sewing machine process. Since the fabric can be easily transported and fed, it is excellent as a method and device for organizing cut fabrics.
