ABSTRACT:
Box blank-forming apparatus (60) is provided which includes a feeder assembly (62) and a scoring/slotting assembly (64) each provided with adjustment structure (62a, 64a) to facilitate makeready adjustment of the apparatus (60) between production runs. The feeder assembly (62) includes a reciprocal pusher element (170) operable to successively engage sheets (30) to be formed into box blanks (36). The element (170) is supported by a pair of elongated, threaded, axially rotatable, fore and aft translatable positioning screws (146, 148), so that upon rotation of the screws (146, 148), a reference position of the pusher element (170) may be varied. This variance is monitored by a servo-sensor (270) for automated control.
