Perforating apparatus and embroidery sewing machine with the perforating apparatus

A perforating apparatus comprising:

• a perforation head including a plurality of vertically reciprocating bars, perforation tools at the lower leading end of the bar, and a perforation blade at the lower leading end of each perforation tool;
• a receiving base arranged below the perforation head, wherein the receiving base includes a circular receiving plate with a window hole at its center through which the perforating blade of a perforating tool from the perforating head may be inserted, wherein the receiving plate is overlaid over top of a receiving member with an downwardly inclined arc surface, wherein the receiving member is configured to receive the perforation blade of the perforation tool through the window hole of the circular receiving plate;
• a holder frame configured to support a workpiece in an expanded state between the perforation tool and the receiving base in a planar direction orthogonal to the vertical direction of the bar, the holder frame being configured to be controlled to move in two-dimensions along said planar direction such as a front/rear direction of the plane direction and a right/left direction of the plane orthogonal to the front/rear direction via motorized drives driven by a controller;
• and
• a cushioning material feed mechanism configured to feed a tape-like cushioning material having a wider width than at least a processing area of the perforation tool, where the mechanism feeds said material from the front/rear direction, between the workpiece supported in the holder frame and an upper surface of the receiving member, wherein the mechanism shifts cushioning material positioned upstream of the receiving member, downstream to the location of the receiving member, at a rate commensurate with the vertically reciprocating motion of the perforation tool.
