Preliminary dough Kt cut into a fan shape is placed on the same plane as the sliding table 13 and on the table 12 connected thereto, overlapping with a bottom paper (not shown) having approximately the same shape as the dough. do. Then, together with the lower paper, the cloth Ktl-upper blade 1 is horizontally swung from an inclined state to a straight state and swung back and forth. This swinging action causes the fabric to be held between the front bottom edge of the upper blade 1 and the lower blade 2 along with the bottom paper, and the horizontal swinging of the upper blade 1 and the lower blade 2 causes the sandwiched fabric to be held between the bottom paper and the bottom paper. By this repeated movement, folds, which will be described later, are sequentially formed at the rear of the lower blade 2.
It is sent to

First, by raising the pleat forming member 3, as shown in FIG. 9, the fabric is pushed up from below to form pleats. In this case, the pleat stopping member 4 is held in the lowered position, and the swinging movement of the upper blade 1 and the lower blade 2 causes the pleat to be held at the fold.
As shown in the figure, the front surface of the upper blade 1 is pressed against the crease stopper member 4 to form a crease.

At this point, the pleat forming part is formed before the blade 1 and the lower blade 2 start swinging.

The material 3 is lowered and placed, and the upper blade 1 and lower blade 2 are returned to their original inclined state as shown in FIG. Release the dough that was held between the two. Before starting this return operation, raise and lower the pleat stopper 4 to touch the creases.
At the same time, when the upper blade 1 and the lower blade 2 return, the pleat stopping member 4 is lowered, and the pleat forming member 3 is completely raised to form a pleat Kt-.

The above-mentioned operation is repeated to continuously form pleats on the fabric K, and the formed pleats K'' are fed into the retention section 50 and heat set.

The above-mentioned rocking of the upper blade 1 from a horizontally inclined state to a linear state and back-and-forth rocking, the movement of the lower blade that swings together with the rocking of the upper blade, and the vertical movement of the pleat forming member 3 and the pleat stopping member 4 are carried out by the main shaft 23. The operation is performed through the above-mentioned mechanisms based on the operation timing based on the rotation of four cams 24, 32, 39 and 43 fixed to the cams 24, 32, 39 and 43.

(Effects of the Invention) The present invention mechanizes the process of forming taper pleats or tapered accordions, which was conventionally performed manually.
It has the following effects.
