ABSTRACT:
To trim a plurality of printed products, which may have different thicknesses, first and second cutting assemblies are provided, each cutting assembly having a cutting knife (98, 59) and a cutting counter element (115, 65). The printed products are held in receivers formed of a fixed jaw and a movable jaw, resiliently clamping the printed products between the jaws, the knives being moved across the printed products and against the counter elements. The printed prroducts are supplied to the first cutting assembly by a pair of toothed or ribbed belt (20) from a storage cassette (1). The length dimension to be cut is determined by a stop rail (39) and the width dimension is determined by the spacing of two lateral knives of the second cutting assembly. A transfer apparatus transfers the printed products from the first to the second cutting assembly, from which they can then be removed. The knives are moved in a guide way formed by guide rails on which sliders operate.
