ABSTRACT:
For cutting multilayer printed products in a continuous process single or multiple printed products 92) are associated with a first knife part (3) which is moved together with the printed products. During the movement, the printed products and the first knife part are engaged along a cutting edge (4) and subsequently moved past a second knife part (5). Through the cooperation between the first (3) and second (5) knife parts, the printed products (2) are cut along the intended cutting edge (4). A corresponding apparatus has a plurality of conveying units for the printed products moving along a circular path. The conveying units are preferably constructed as counterknives while the associated cutting knives are fixed. Thus, even when large quantities are conveyed and the printed products are thick, a top-quality three-sided cut is obtained.
