Abstract: A method for operating a processing roller of a processing machine having a circumferential length and comprising a tool having a tool length extending in the circumferential direction is disclosed. A processing length extending in the circumferential direction is defined, along which the tool is engaged with the material to be processed during processing. A compensation length in the circumferential direction is further prescribed, along which a compensation motion of the processing roller is performed, wherein the tangential velocity of the processing roller is negative at least at times. The compensation length is determined using the circumferential length, the processing length, and the tool length.

Abstract: A method for operating a transverse machining roller of a transverse machining device, which is driven by means of a drive unit and is for the rotary machining of a product web that is transportable in a transport direction, in order to produce machined sections of product web of different formats, having the following steps: selection of a desired format for the sections of product web, preparation of a number of motion rules for controlling a rotary movement of the transverse machining roller in a control unit, for the desired format, production or calculation of a movement of the transverse machining roller on the basis of motion rules prepared in the control unit and/or at least one parameter of the drive unit and/or at least one instruction of a user.
