ABSTRACT:
Apparatus for trimming the lateral marginal portions of successive stacks of sheets of multiple unit width and for subdividing the trimmed stacks into stacks of unit width has an advancing unit which moves the stacks stepwise in a direction at right angles to their width, a trimming station where the marginal portions of successive stacks are trimmed, and two or more severing stations which are disposed one after the other, as considered in the direction of advancement of the stacks, and at each of which the width of the stacks is reduced by one unit width as a result of separation of discrete stacks of unit width therefrom. The stacks at the severing stations are moved sideways by the width of a stack of unit width prior to a separating step. The mechanisms at the severing stations employ knives which are aligned with one another, as considered in the direction of advancement of stacks, and are accessible at the outer sides of the respective severing stations.
