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.
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 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, wherein the first rotating device and the second rotating device are arranged one after the other in the transport direction, and each rotating device comprises rotating means, which engage with the product for the rotating process, wherein at least the first rotating device comprises switchable engagement means by means of which the rotating means can be engaged with or disengaged from the product at selected times.
Method for rotating flat products, particularly sheets or stacks of sheets, moved in a transport direction from a first orientation into a second orientation by a predetermined total rotation angle by a first rotating device in which the product is moved first by a first rotation angle and by a second rotating device in which the product is later rotated by a second rotation angle, wherein the first rotating device and the second rotating device are arranged one after the other in the transport direction, and each rotating device comprises rotating means, which engage with the product for the rotating process, wherein the rotating means of the first rotating device are disengaged from the product at selected times by switchable engagement means, while the product is engaged with the rotating means of the second rotating device.
