Abstract: A device for stacking sheet material in the form of individual stacks comprises a fixed stop, a vertically movable stop, a support surface, a sensor and a guide member, to which two pushers are fastened, which are activated by lifting cylinders. The sheet material to be stacked is conveyed by conveying rollers and falls down freely between one of the stops and a stop face where the individual stacks are formed. The guide member can be raised and lowered about a pivot by means of a lifting cylinder which engages a pivot point provided at the underside of the guide member. Stacking is performed in individual stacks, whereby two super-imposed individual stacks each are mutually offset in the direction of transport Z by a distance of displacement x.

Abstract: A roll frame which has two arched rolls, the radii of which can be adjusted by an adjustment crank. Adjacent material formats, such as printing plates or printed circuit boards, are separated parallel to each other transversely to the running direction by an individualizing interval when running through the feed nip between the two arched rolls. The individualizing interval is directly proportional to the format length and the format width of the printing plates or printed circuit boards, and indirectly proportional to the square root of the difference of the squares of the arched roll radius and half the format width.
