In other words, the mounting plate 3 is ready for bending.
moves from the original position S _B to the bending position S _F , and in this bending position S _F , as shown in Fig. 7b,
The tip of the pressing member 5 is waiting while being positioned on the upper surface side of the half portion 50a hanging down from the placement plate 3 of the cloth piece 50, and the first and second pressing members 8 and 9 begin to descend.

In FIG. 7c, the pressing member 5 starts pressing movement toward the tip side, and the half 5 of the cloth piece 50
0a is bent toward the back side of the mounting plate 3 using the end of the mounting plate 3 as a bending point.

By further pressing movement of the pressing member 5, the half portion 50a of the cloth piece 50 is bent as shown in FIG. 7d. At this time, the first and second pressing members 8,
9 move in a direction closer to each other, that is, toward the mounting plate 3 side, and the folded portion and end portion of the cloth piece 50 are placed on the pressing surfaces 19 and 28, respectively. In this state, the mounting plate 3 starts returning to the original position S _B , and as a result, the piece of cloth 50 is left behind on the pressing surfaces 19, 28 in a folded state.

In FIG. 7e, the first and second pressure members 8 and 9 move upward, and the folded portion and both ends of the piece of cloth 50 are pressed against the first pressure member 8 and the first pressure receiving member 6.
and between the second pinching member 9 and the second pressure receiving member 7, respectively. Further, the pressing member 5 is operated to return to its original position.

In this way, a center hold-shaped cloth label is formed, and the first and second pressure receiving members 6,
7, and when the clamping state by the first and second clamping members 8 and 9 is released, the cloth label is taken out upward by a taking-out means (not shown). On the other hand, original position S _B
The next piece of cloth 50 is placed on the mounting plate 3 that has returned to the original position, and a cloth label is formed through the same process as described above, and in this way, cloth labels are formed one after another.

C. Effects of the Invention As described above, according to the present invention, the piece of cloth supplied onto the mounting plate is prepared for bending by the inclined guide plate, and is bent by the pressing operation of the pressing member,
Furthermore, by being pressed by the first and second pressure receiving members and the first and second pressing members, a center hold-shaped cloth label is formed. Moreover, the mounting plate driving means, the pressing member driving means, and the first and second pinching member driving means are interlocked and connected to a single rotational drive shaft, and are dependent on the rotational movement of the rotational drive shaft. Since the mounting plate, the pressing member, and the first and second pressing members can be operated synchronously according to the timing, operating errors can be significantly reduced compared to conventional systems that use solenoids, air cylinders, or air nozzles. It is possible to form a cloth label with an accurate center hold shape.
