In this example, the dough transfer area of the apparatus of the present application is, as shown in FIG. 5, a strip-shaped dough 1 fed in a single width direction from the lower right side toward the diagonally upper left direction on the way. From the rear side, the material 1 is folded in three and comes out, and is guided to, for example, a sewing portion of a sewing machine (not shown). ing.

A guide plate 2 for guiding the belt-shaped cloth 1 which is pulled in the longitudinal direction by the sewing portion of the sewing machine (not shown) is positioned on the entrance side of the cloth transfer area. The guide plate 2 has a substantially rectangular shape when viewed from the front, and the left side of the surface is formed in a gentle convex shape in front of the right side,
It is fixed to the upper part of the side surface of the plate-shaped mount 4 via the support 3 provided on the back side. The dough 1 is supplied to the guide plate 2 from the lower side to the upper side in a single state in the width direction [see FIGS. 7 (a) and 7 (b)], and the front side of the dough 1 is contact-guided.

A first side edge regulating plate 5 is located at the right end of the cloth movement area in which the cloth 1 is guided by the guide plate 2. This first
The side edge regulating plate 5 is attached to the tip of the rod 7 of the air cylinder 6. The air cylinder 6 is provided through the tip of the support plate 9 and is fixed by nuts 10 and 10. The support plate 9 is fixed to the horizontal portion 4a of the frame 4 with screws 8. The support plate 9 is obliquely inclined on the left side in the front view in the middle, and therefore, the first side edge regulating plate 5 is arranged in the width direction (arrow direction) of the cloth 1 guided by the guide plate 2. The position can be adjusted (see Figures 1 and 5).

The first side edge regulating plate 5 has a U-shaped cross section so as to guide the right side edge of the cloth by sandwiching the right side edge from the front and back sides, and is guided by the guide plate 2 at the inner side thereof. Dough 1
The right side edge is regulated while guiding the right side edge.

The right edge portion of the cloth 1 that has passed through the guide plate 2 and the first side edge regulating plate 5 is guided to the second folding plate 12. This second
The folding plate 12 is attached in the same manner as the first side edge regulating plate 5, and is attached to the tip of the rod 14 of the air cylinder 13 as shown in FIG. The air cylinder 13 is penetrated by a support plate 16 fixed to the pedestal 4 with screws 15, and two nuts 14,1
It is fixed to the support plate 16 at 4. Therefore, the position of the second folding plate 12 can be adjusted in the direction of the hollow arrow (see FIGS. 2 and 5).

The second folding plate 12 is formed by bending a substantially rectangular metal plate in the width direction so as to have an arcuate cross section.
The two wide surfaces are oriented in the vertical direction, and the right edge of the cloth 1 rising from the lower right toward this is guided from the right side while being pressed from above. As a result, as shown in FIGS. 7D and 7E, the right side edge portion of the cloth 1 is widened at the first bending position A near the right side edge C while widening the folding width with the surface side outward. It is folded in two and folded in two directions.

On the other hand, the rest of the dough 1 part except the right side edge part is the first
Is guided to the return plate 20 of. The first folding plate 20 is, for example, as shown in FIGS. 6 (a) and 6 (b), a flat metal plate in which the left side is longer than the right side and the rate of increase in length is small in the middle. Is bent so that the right side is above the left side, and the cross section is formed in a U shape.
The outer surface on the lower side is welded to the left end of the gantry 4 with a in the front-back direction when viewed from the front. The first folding plate 20 is
In addition to the example, a trapezoidal flat metal plate whose increase rate does not change may be used. Further, the position adjusting direction of the folding plate 12 in FIG. 2 is a direction aligned with the direction in which the front end of the first folding plate 20 located above the bent portion 20a extends. In addition, the middle portion of the lower side of the first folding plate 20 is slightly recessed so that a second side edge regulating plate 25, which will be described later, can be inserted into the recess 21.

The dough 1 guided to the first folding plate 20 is designed to be transferred rearward from the entrance side end located on the front side, and therefore, as shown in FIG. When passing through the edge, the remaining cloth 1 part excluding the right side edge is folded in the width direction at a second bending position B closer to the left side edge D than the first bending position A with the surface side as the outside,
After that, while being transferred along the inner surface of the first folding plate 20, it is folded in two as shown in FIGS. 7 (d), (e) and (f). Since the first folding plate 20 is formed as shown in FIGS. 6 (a) and 6 (b), it has an opening 20b along the cloth movement area.

In the recess 21 formed on the lower side of the first folding plate 20, the width direction of the part of the cloth 1 passing through the first folding plate 20, that is, the left and right direction (black coating in front view as shown in FIGS. 1 and 5). The second side edge regulating plate 25 is attached to the upper surface of the moving support body 23 that moves in the arrow direction) and can move in and out. As shown in FIG. 4, the movable support 23 has a rod-shaped slider on the back surface.

It is inserted in a and 27a. Further, in order to prevent the moving support 23 from rotating around the slider 28, the guide
An intermediate portion of 27 is cut out in a concave shape, and a rotation preventing body 29 is attached to a slider 28 portion located in the concave portion 27b. Further, a bent portion 23a to the right is formed at the lower end of the moving support 23 so that the bent portion 23a abuts the front side surface of the gantry 4.

Such a second side edge regulating plate 25 has a U-shaped cross section, and the opening 25a is oriented rightward in front view so that the opening 25a sandwiches the left side edge of the cloth 1 from the front and back sides, The lower surface is attached to the upper surface of the movable support member 23.

The left side edge of the cloth 1 guided by the first folding plate 20 is guided by the second side edge regulating plate 25 and the position of the left side edge is regulated. Further, since the right side edge of the fabric 1 is regulated by the first side edge regulation plate 5 as described above, the fabric 1 is regulated at both side edges over the entire area from the entrance side to the exit side without shifting in the width direction. The dough transfer area can be transferred in this state.

The dough 1 guided to the first folding plate 20 through the second folding plate 12 is guided on the inner surface of the first folding plate 20, and at the two first and second folding positions A and B. Each of them is folded with the front surface side outside, and one side edge portion folded by the first folding is put inside, that is,
It will be in the shape of a letter and goes out from the exit side end of the first folding plate 20,
It is sent to the downstream side and guided to the sewing portion of the sewing machine (not shown).
