Claims (1)

[Scope of utility model registration request] The conveyor section is equipped with multiple comb-shaped presser plates.
In an automatic sewing machine that moves along the side of the sewing machine to sew the cloth set on the conveying section, one end has a comb-like shape that can move back and forth between the plurality of presser plates, and the base end L with parts connected together
A mold positioning sheet metal and a presser plate, a slide member that supports the L-shaped positioning sheet metal and the presser plate and is slidable up and down relative to the substrate, and a slide member for moving the L-type positioning sheet metal and the presser plate back and forth between the presser plate plates. a moving means for moving the board back and forth, a cylinder for normally holding the slide member in the raised position and once lowering the slide member after the board has returned to its original position, and then pressing it upward again; A cam is installed so that it can swing angularly and always receives elastic force in one direction, and a stopper is fixedly arranged opposite to the cam.The cam engages with the end face of the stopper during the return of the board and rotates. By doing so, the board is allowed to return to its original position while the slide member is maintained in the raised position, and the cam is then released from engagement with the stopper end face by lowering the slide member by the cylinder and positioned below the stopper member. and then when the slide member is raised via the cylinder, the cam engages with the lower surface of the stopper to maintain the slide member at an intermediate position between the raised and lowered positions. Preset device.
