して各種の手段もに開発実施されている。 Needless to say, various knitted and woven fabrics have flexibility unique to fabrics, and while this characteristic allows them to be folded freely, it also creates constraints and difficulties when mechanizing or automating this process. That is, there are problems such as the occurrence of wrinkles or sagging during movement or operation, and the fact that the given shape collapses even with the slightest external force. When folding such a knitted or woven fabric in half, the difficulty in handling the work is further doubled when the work is a finished product, such as a cut piece of fabric or a semi-finished product that has been sewn or otherwise processed. For such workpieces, forced gripping, clamping, or fixing means often cause scratches or strong creases on the workpieces. However, these workpieces are large in quantity, and it is disadvantageous in terms of time and cost to do it manually, and it is difficult to do it smoothly and efficiently without damaging the workpieces. There is a need for mechanized and automated means for folding, and various means have been developed and implemented to meet this purpose.

３，４図に示す順序に行なわれる。 Folding operations such as folding the work cloth 15 in two according to the present invention, further folding the work cloth 15 that has been folded in two in two, are performed as follows.
This is done in the order shown in Figures 3 and 4.

出させる。 In the conveying member 1, when the completely unfolded work material 15 is carried by the belt 6 as shown in the second figure, at the arrival position shown in the figure, for example, the front end or rear end of the work material 15 is moved by a photoelectric tube or other automatic device. This is confirmed by the sensing means, and an air stream is ejected from the nozzle 12a of the air chamber 12 in the air stream supply chamber 11 in a substantially horizontal direction as shown by the arrow.

１０は矢印方向に回動させる。 This jet of air flow is caused by the fact that the leading end side of the work material 15 is moved from the unloading end of the belt 6 to the reversing roller 1 of the winding section 7.
If there is no such air jet, if the workpiece material 15 is a flexible material that lacks waist strength, especially the tip of the workpiece material 15 will be difficult to carry out. It hangs down from the end and enters between the illustrated reversing roller 10 and the belt 6, that is, into the folding slit 9, making it impossible to fold it in two as intended. Due to the jet air negative pressure caused by this air flow ejected from the nozzle 12a, the workpiece material 15 is suctioned and raised in the direction of the arrow streamline of the air flow, and automatically advances in the same direction as the air flow direction. do. this time belt 6
Above, the work material 15 is attached to the tip 1 of the sliding plate 14.
4a, it is press-contacted onto the belt 6 so as to be able to move forward, and accordingly, as the belt 6 advances in the arrow direction, it moves in a substantially horizontal direction on the winding part 7 as shown by the dotted line, and the winding part 7 is moved in a substantially horizontal direction. It will be carried over. If the work material 15 is particularly thin and light when the sliding plate 14 is not pressed, there is a risk that the work material 15 will be blown away due to the air flow. Further, the reversing roller 10 is rotated in the direction of the arrow.

うものであつてもよい。 As described above, when the workpiece cloth 15 is transported by the belt 6 and suspended over the winding part 7, and when the predetermined folding position of the workpiece cloth 15 reaches the lower surface of the nozzle 13a of the air chamber 13, As mentioned above, this arrival is detected and confirmed by a phototube or other sensing member, and at the same time, the reversing roller 10, which was in the rotation direction of the arrow in FIG.
Rotate it in the opposite direction as shown by the arrow in the figure, and at the same time feed the workpiece material 1 from the nozzle 13a of the air chamber 13 in the vertical direction as shown by the arrow, that is, toward the folding slit 9.
It is sprayed on five sides. At this time, the air jetting from the nozzle 12a of the air chamber 12 is stopped in advance. As a result, as shown in the figure, the workpiece material 15 is blown into the slit 9 with its folded position at the beginning, and the subsequent left and right portions are sequentially folded into a V-shape and into two-fold shapes along the belt 6 roller 10 surface. It progresses downward from the slit 9. At this time, by making the gap between the folding slits 9 wide enough to properly nip the workpiece material 15, the two-folded material 15 is automatically and smoothly sent downward while being nipped between the slits 9. It turns out. Further, the vertical air injection from the air chamber 13 is stopped when both ends of the work cloth 15 are nipped between the belt 6 and the reversing roller 10. Figure 4 shows the progress of the two-fold folding, and the folding point of the two-fold is 2 in Figure 1.
This figure shows a state in which the work cloth 15a, which has been folded in half by the conveyance of the belt 6, reaches the next winding part 8 and the air flow supply chamber 11 in the first illustration. However, at this time, the conveyance speed of the belt 6 in FIG. 4 is set to be slightly faster than the rotation speed of the upper reversing roller 10 indicated by the arrow. The surface of the work material 15a in contact with the belt 6 is fed out a little earlier,
It falls onto the belt 6, and in this case, if the speed of the belt 6 is made slower than the roller 10,
The fabric 15a is undesirable because it curves in the opposite direction. Moreover, when the 7-7 dough 15 has passed between the folding slits 9, the reversing roller 10 returns to the rotation indicated by the arrow in FIG. 2 in preparation for the next work material 15. This does not necessarily have to be performed by forced driving, and the reversing roller 10 may be provided in an idling manner to perform forward and reverse rotation.

As shown in the first figure, at the second folding position, a can be folded in two and then folded in two again, making a total of four folds, but the repetition of this two-folding process depends on the size of the workpiece material 15 and the purpose. Needless to say, you are free to repeat the process as many times as you like.

利である。 The folding of the work dough according to the present invention is as described above, and since the work dough 15 is folded with airflow, the work dough 15 is always kept in an appropriately stretched state without wrinkles or sagging, regardless of the material. It is operated in the original position and a good folded shape is obtained. Furthermore, since the fabric 15 is folded into two by the ejected air flow, it is carried out with great precision and accuracy, and the folding speed is also intermittently depending on the conveying speed of the cloth conveying member. The position of the two-fold can be changed freely, for example, by using a timer or other auxiliary means.
Continuous processing is possible as long as the initial inputs do not overlap, and there is no problem with large-scale processing.In particular, since everything is operated by air flow, there is no risk of damage to the fabric. It does not cause excessive stretching, and is especially suitable for drapey and slightly stiff knitted fabrics such as women's long socks, but it can be suitably applied to almost all types of fabrics, such as forced gripping, pinching, etc. Since there is almost no contact friction due to the rigid body, it is excellent because it enables efficient automation of folding work without fear of quality deterioration, and as a device it is extremely simple and does not require complex mechanical layouts and combinations. It is extremely advantageous in that it does not

置。[Scope of Claims] 1. A fabric that is fed along a conveyance member whose upper surface is a fabric placement surface and which continuously conveys the fabric in a horizontal direction, and whose conveyance end surface is a rotating circumferential surface that continuously rotates. The winding is carried out on the winding portion formed by the rotary conveyance end surface of the conveyance member and a reversing roller which can be forward-reversed and which is opposed to it through a folding slit that can bit the two-folded fabric. After the fabric is lifted and moved across the rack by an air flow that is injected horizontally from the section entrance into the space parallel to the fabric conveyance direction and above the fabric, the fabric is directly faced to the folding slit at the center of the winding section. After the cross-over fabric is transferred into the slit in the form of two folds by an air flow jetted downward in the vertical direction and in the direction orthogonal to the fabric conveyance direction, the rotating conveyance end surface and the reversing roller are rotated. A fabric folding method characterized by biting the fabric into two and transporting it downward. 2. A fabric conveying member whose upper surface is a fabric placement surface and which continuously conveys the fabric in the horizontal direction, and whose conveying end surface is a rotating circumferential surface that continuously rotates, and a rotating conveying terminal end of the conveying member. A fabric wrapping section consisting of a reversing roller that can be rotated in forward and reverse directions and opposed to each other through a folding slit that can bit the fabric folded in half; an air jet supply means for passing the dough, which opens in a space above the dough in a horizontal direction with respect to the dough conveying direction; 1. A fabric folding device comprising: an air jet supply means for folding the fabric in half across the rack, which is wide and opens in a direction perpendicular to the fabric conveyance direction.
