Fly edgestitching apparatus

An edge stitching device for a fly, wherein

• the fly, which is an object to be stitched, includes a lower fly body having an edge where a horizontal side and a vertical side extending straight in intersecting directions are joined by a curved side, in which a slide fastener on an upper side is superimposed on the fly body, an extending direction of the vertical side is aligned with a longitudinal direction of the slide fastener, two end portions of the fly body in an extending direction of the horizontal side are protruded from the slide fastener to two width direction sides of the slide fastener,
• the edge stitching device comprises:
• a table on which the fly is placed;
• a clamping device which sandwiches the fly in cooperation with the table;
• a sewing machine which edge-stitches an edge of the fly body and is provided on the table;
• a cutter provided in the sewing machine and configured to cut the fly body to form the curved side in the edge of the fly body;
• and
• a clamping device conveying device which conveys the clamping device in a state where the fly is sandwiched by the clamping device in the cooperation with the table,
• the clamping device conveying device continuously performs:
• pre-edge-stitching conveyance, in which the clamping device is linearly conveyed toward the sewing machine in a state where the fly is sandwiched before edge stitching;
• and edge stitching conveyance, in which the clamping device is conveyed in a state where the fly is sandwiched during the edge stitching, and
• in the edge stitching conveyance, the clamping device is conveyed in accordance with a shape of the curved side formed by the cutter.
