Apparatus for processing flat objects

Apparatus for processing flat objects comprising a transport system with several rotatably mounted conveyor rollers, with which the flat objects are transportable in the direction of transport, and a plurality of releasably mounted tool modules,

• a) which comprises a casing;
• b) which is releasably coupled to only one drive shaft or to a lower and an upper rotatably mounted drive shaft;
• c) which is supported displaceable along the only one drive shaft or the lower and the upper drive shaft;
• and
• d) which is equipped with two tool parts that are mounted in the casing and that are arranged for interacting with one another for processing the flat objects, of which tool parts at least one is drivable by the lower or the upper drive shaft;
• wherein each tool module of the plurality of releasably mounted tool modules is supported on a respective tool carrier of a plurality of tool carriers which is individually displaceable by means of a rotatably mounted setting shaft of a plurality of setting shafts in parallel to the only one drive shaft or in parallel to the lower and the upper drive shafts, and
• wherein each tool carrier of the plurality of tool carriers has at least one holding element which serves for releasably holding the respective tool module of the plurality of releasably mounted tool modules.
