The actuating member 25 has an actuating plate 29 formed at its upper end, and the actuating plate 29 is parallel to the working surface 2 and is formed to protrude toward the guide plate 18 of the guide member 17. . Further, a hole 5 is formed in the work table 3, and the actuating plate 29 enters the hole 5 in a first position;
It emerges from the hole 5, is moved to the left in FIG. 1, passes through a second position located directly above the regulating portion 19, and reciprocates between the position where it abuts the work surface 2 of the work table 3. Ru. The operating member drive unit is configured as described above.

Further, a third base 30 is installed on the overhang 4, and a pulse motor 32 is installed on this base 30.
Accordingly, the movable table 31 is installed so as to be able to reciprocate along the cloth feeding direction F. A solenoid 33 is fixed to this moving table 31.
3, a feed foot 35 is fixed to an operating shaft 34.

are arranged on a straight line passing through the regulating portion 19, and are biased by the solenoid 33 in the direction of coming into contact with or separating from the work surface 2, respectively. The feed foot drive unit is configured as described above, and the feed foot 3
5 presses the work cloth against the work surface 2 and moves it in the cloth feeding direction F
The material is then moved away from the work cloth and returns to its original position.

Next, its effect will be explained.

First, the operator determines the position where the edge of the work cloth is to be folded, and places the restriction part 1 of the guide plate 18 of the guide member 17 there.
Set the work cloth so that 9 is facing. At this time, the guide member 17 and the feed leg 35 are located above the workpiece cloth, and the operating plate 29 of the operating member 25 is located within the hole 5.

Next, the operator urges the guide member 17 toward the workpiece cloth to start the apparatus. At this time, the guide plate 18 is in light contact with the work cloth.

First, the actuating member 25 is raised by the drive of the pulse motor 27, and its actuating plate 29 lifts up the edge of the work cloth. Next, the pulse motor 23 is driven to move the moving table 24 to the left in FIG.
The actuating member 25 moves toward the regulating portion 19 of the guide plate 18, and the edge portion is folded in by the cooperation of the actuating plate 29 and the guide plate 18. Next, the feed foot 35 is urged toward the work cloth and presses the folded work cloth. Next, the moving table 1 is driven by the pulse motor 13.
4 is moved to the cloth feeding side, and the guide plate 18 is removed from below the actuating plate 29. At this time, the work cloth is pressed by the feed foot 35 and therefore does not move.
The actuating member 25 is then lowered by the pulse motor 27 and presses the work cloth against the work surface 2 to form a crease. Next, by driving the pulse motor 23, the moving table 24 is moved to the right in FIG.
9 is removed from the work surface 2. Next, the actuating member 2
5 is lowered by the pulse motor 27, and the actuating plate 2
As the guide member 9 enters the hole 5, the guide member 17 is separated from the work cloth, moved in the cloth feeding direction F, and returns to the initial position where it lightly contacts the work cloth. After entering the hole 5 of the actuating plate 29, the feed leg 35 moves the work cloth in the cloth feeding direction F by driving the pulse motor 32, leaves the work cloth, and returns to the initial position again. By repeating the above operations, the edges of the work cloth are continuously folded and creases are formed. After forming a crease on one side of the work cloth in this manner, the operator only has to form a crease on the other side.

In addition, in the present invention, if the work cloth is transferred according to a predetermined pattern, creases can be formed along the periphery of the work cloth, and work cloths of various shapes can be handled. .

[Effects of the Invention] Since the present invention is configured as described above, the edges of the work cloth are folded in continuously, so that changes in the shape of the work cloth can be accommodated.
