うになる。In the device described above, the cloth coming out of the guide plate expands due to its restoring force and becomes rounded.In particular, at the start of sewing, unless the presser foot is raised, the presser foot can be used. Become supportive. Therefore, usually, the presser foot is raised and the cloth is advanced under it, then the presser foot is lowered and sewing is started.However, when the presser foot is lowered, the folded end of the crushed cloth is fed by the cloth feed. It protrudes from the line, and only the start end of the sewing becomes deep sewing.

にするのがより望ましい。That is, in the present invention, a guide ruler is provided near the front of the presser foot,
Further, two horizontal guide plates having upper and lower edges in front of the cloth feed direction, and an intermediate guide plate fitted between the two guide plates so that the edges intersect with the edges of the guide plates. The cloth is conveyed by a belt conveyor placed on a sewing machine table, passed between the three guide plates, the cloth edge is gradually bent deeply into an S shape, and the outer surface of the lower bent portion is brought into contact with the guide ruler. In an automatic swivel stitching device in which the inner surface is brought into contact with the edge of the lower guide plate and the bent portion is guided on the cloth feed direction line passing through the needle drop of the sewing machine and sewn to the cloth edge, A fumarole is provided between the presser foot and the guide plate, and air is blown downward to the cloth immediately after being released from the guidance by each guide plate to control the swelling of the cloth. It is characterized by keeping it under that and guiding it under the presser foot It is intended. According to the present invention, the S-shaped bent portion of the cloth coming out of the guide plate is fed under the presser foot while maintaining a flat S-shape from the sewing start end by blowing air, and Proof stitching can be performed at the same depth. Also, by pressing the bent part under the S-shaped bend from the outside with the protrusion of the guide ruler and from the inside with the protrusion of the lower guide plate, the bend can be corrected smoothly. The bent portion can be positioned correctly.However, in order to facilitate the correction of the bent portion, a concave portion is provided on the protrusion in front of the protrusion of the lower guide plate. It is desirable that the guide ruler of the intermediate guide plate and a portion corresponding to the lower guide plate facing the ruler be cut out so that the cloth can move smoothly. In this case, it is more preferable that the upper guide plate is made transparent so that the movement of the edge of the cloth and the lower bent portion immediately before being fed under the presser foot can be visually confirmed.

なっている。The folding device 6 includes a pair of support brackets 12 on a table.
A transparent upper guide plate 13 supported in the front and rear direction, and a fixed space between the upper guide plate 13 and the upper guide plate 13 via a spacer 14 under the upper guide plate 13 with a fixed interval, and the edge is cloth fed together with the upper guide plate 13. A lower guide plate 15 that is bent along its direction and its front end is bent upward to make it easier for the cloth edge to enter therebelow. As shown in FIG. , The front and rear guide plates 13 and 15 are provided with an appropriate play between the upper and lower guide plates, and fitted so that the edges intersect with the edges of both guide plates, and the front end faces downward. The intermediate guide plate 17 is bent to one side, and one side edge of the front side faces the front end edge of the lower guide plate 15 and the front end is positioned below the presser foot 9, and the front side end and the front end And a guide ruler 18 protruding toward the lower guide plate side.The lower guide plate 15 has a projection 15a at the end of the edge. A projection 15a is formed between the projections 18a, and a slightly recessed portion 15b is formed in front of the projection 15a so as to smoothly move the cloth when correcting the bent end. (See FIG. 3).
The intermediate guide plate 17 has a projection 15a and a concave portion 15b of the lower guide plate 15, and a portion corresponding to the front side of the guide ruler 18 facing the guide portion guides the upper bent portion (the square portion shown in the figure). ) Is cut off, and the movement of the fabric edge and the lower bent portion immediately before being sent under the presser foot through the transparent upper guide plate 13 can be visually confirmed, and the upper part to the bent portion can be confirmed. By releasing the presser, the movement of the cloth edge becomes smooth and the bent end can be easily corrected, and the upper guide plate passes through the long hole 19 of the suspension bracket 16.
The position is adjusted in the direction orthogonal to the cloth feeding direction within the range of the elongated hole 19 by the bolt 21 screwed into the 13 so that the fitting depth between the upper and lower guide plates 13 and 15 can be changed. On the other hand, the upper guide plate 13 protrudes from the lower guide plate 15 and extends on the guide ruler 18 at the tip. By changing the holding position of the support bracket 12 with respect to the rod 12a, the position is adjusted together with the lower guide plate 15 in a direction orthogonal to the cloth feeding direction, and the amount of the support bracket 12 placed on the guide ruler can be changed.
