The ODM Stomper is a 30″ (76 cm) air operated turning in machine. This is the third step in making a hard cover case. This machine wraps the cover material around the board to hide its edges. The climbing action of the turning-in bar ensures a tight corner wrap of materials from leather to library buckram. The optional Slicer is a corner cutter to which prevents the bunching of excess material in the corners of the case.
