At the bottom of the punch slot is a horizontally reciprocating punch which forms the holes. Meanwhile, a second batch is bieng jogged and segregated. The first and second batches are gripped and lifted. The first batch is deposited in a vertical discharge slot from which it is transferred to a deposit tray. The second batch is simultaneously punched while in the punch slot.
