Next, the operation of this embodiment will be explained with reference to FIGS. 2 to 5. First, when the preset device is in the set position as shown in FIG. Upon contact, the slide plate 19 rises to an intermediate position. Therefore, the other end 28b of the L-shaped positioning plate 28 is in contact with the receiving plate 30;
The other end 29b of the holding plate 29 is separated upward from the receiving plate 30. In this state, if the cloth 15 is inserted along the top surface of the board 16, the cloth 15 can be inserted between the board 16 and the holding plate 29, and the other end 28b of the L-shaped positioning plate 28 is used to insert the cloth 15. The tip can be positioned.

Furthermore, when the operating shaft of the cylinder 23 is lowered as shown in FIG.

Effects of the invention According to the invention, a limiting member is provided at the preset position to limit the raising of the slide plate at the preset position to an intermediate position between the raised position at the set position. Since it can be operated in three stages, the preset position can be moved to a state in which only the L-shaped positioning plate is pressed against the receiving plate, and a state in which the L-shaped positioning plate and the holding plate are pressed against the receiving plate, and also in the set position. Now, both the L-shaped positioning plate and the holding plate can be moved between a state in which they are pressed against the receiving plate and a state in which they are separated upward from the receiving plate.

This makes it possible to insert, position, and hold the cloth in the preset device at the preset position, and even an unskilled person can easily transfer the cloth at the set position without causing the cloth to shift. Furthermore, since the setting and delivery of these cloths can all be done using a single cylinder, there is also the effect that the mechanism is simplified.
