ABSTRACT:
In a method of and apparatus for breaking away of prepunched pieces from a curved or arched sheet of material, the sheet is applied to a block, and the pieces of material to be broken away are individually engaged between a pointed component acting on the upper surface of the sheet and a counter pressure mounting support acting on the lower surface of the sheet. Said pointed component on downward movement penetrates said upper surface only to the extent necessary to prevent relative lateral movement between the two, and said counterpressure mounting support supports oppositely disposed edge portions of the piece of material to be broken away, continuing downward movement of said pointed component causing said piece of material to bend under load to the extent that it loses its holds on said edge portions and is pushed through said mounting support to be released from said pointed component on leaving said mounting support.
