Abstract (en)
A machine for punching holes in batches of sheets has a receptor which holds a stack (49) of sheets in vertical position. A timing mechanism sequentially jogs and segregates a first batch (124) from the receptor and deposits same in a vertical punch slot (207). At the bottom of the punch slot (207) is a horizontally reciprocating punch which forms the holes. Meanwhile, a second batch (125) is being jogged and segregated. The first and second batches (124, 125) are gripped and lifted. The first batch (124) is deposited in a vertical discharge slot from which it is transferred to a deposit tray. The second batch (125) is simultaneously punched while in the punch slot (207).
