ABSTRACT:
Packet blanks are fed stepwise along an elongated blank bed by a succession of pawls reciprocating along the length of the bed. Mechanism is provided for lifting the pawls at the end of their working strokes, and for lowering them at the end of their return strokes. In the event that the blank feed is to be interrupted, the mechanism can keep the pawls lifted without stopping reciprocating movement of the pawls.
