Abstract:
A process for forming small stacks from an initial stack of sheet material by cutting, said process comprising:providing a single guillotine cutter machine which comprises a rear table part for receiving the material to be cut and a front table part for receiving the cut material; separating the initial stack into partial stacks by a plurality of cuts in a first direction perpendicular to a direction of feed thereof; pushing back and rotating 90Â° at least a portion of the partial stacks from the front table part on to the rear table part for further cutting; horizontally repositioning an alignment station with respect to the front table part to a position above the front table part, the alignment station including a first moveable guide plate; advancing the partial stacks such that the partial stacks abut the first guide plate; cutting the partial stacks in a second direction substantially perpendicular to the first direction to produce small stacks; moving apart the front and rear table parts to form a gap between them; placing a second movable guide plate substantially within the gap; and transporting the small stacks through a transverse channel formed between the two guide plates to a further processing station.
