ABSTRACT:
Faulty useful units printed on a sheet of useful units are separated from the acceptable useful units. A first cutting device cuts the sheet into a plurality of longitudinal strips, each of which contains several of the useful units. A quality control device detects the faulty useful units prior to a second cutting device that cuts the strips into individual units. A filtering unit is placed between the two cutting units and filters out strips with one or more faulty units. Strips with no faulty units replace the filtered out faulty unit strips. This simplifies further processing of the strips.
