A device for rotating flat products, in particular sheets or stacks of sheets, moved in a first direction from a first orientation into a second orientation, by a predetermined total rotation angle, by means of a first rotating device, in which the product is rotated first by a first rotation angle, and by means of at least one second rotating device, in which the product is later rotated by a second rotation angle. The first and second rotating devices are arranged one after the other in transport direction, and each rotating device includes rotating elements, which engage with the product for the rotating process. In order to be able to process products having different formats at the highest possible throughput and as failure-free as possible, and in order to ensure as mild a treatment of the products as possible, at least the first rotating device includes switchable engagement elements by means of which the rotating elements can be engaged with or disengaged from the product at selected times. |
