ABSTRACT:
A scrap knockout for use with a rotary punching apparatus includes a knife cylinder equipped with punch blades on the outer peripheral surface, and an anvil cylinder having a layer against which the blades are pressed, so as to punch a workpiece fed in between the two rotating cylinders. The scrap knockout is so arranged that each of the punch blades is formed with a cut or slot, and a scrap knockout lever is engaged with the cut or slot so as to be restricted in its upward and downward movements, with one end of the knockout lever is a free end located in the space surrounded by the punch blade and the other end is pivotally held by a punch blade support, so that the scrap formed by the punching can be removed by the upward motion of the lever.
