<p>The present invention addresses the problem of suitably processing a workpiece that has comparatively high rigidity and resistance to needle insertion, such as leather, by an embroidery sewing machine that sews while controlling movement of the workpiece in two-dimensions. An embroidery sewing machine comprises a normal embroidery head (3), a perforating head (4) that includes a rod (4a) that moves up and down and a perforating tool (21) provided on the distal end of the rod, and a receiving base (35) that is disposed under the perforating head and that receives the perforating tool that was lowered with the downward movement of the rod. At least one of embroidery sewing and perforated pattern forming is performed on a workpiece (H) by selectively using one of the embroidery head and the perforating head. For example, a desired perforated pattern is formed on the workpiece using the perforating head, and then embroidery sewing is performed using the embroidery head on at least a portion of the perforations of the perforated pattern that was formed on the workpiece.</p> |
