Abstract
A crosscutter device (10) for producing portions from printing formats following one another endlessly in the transport direction (18) of a printed flat web (16) has two cutting units (12, 14) for the flat web (16), spaced apart from each other in the transport direction (18). Each cutting unit (12, 14) has a stationary knife (24, 34) and a knife (22, 32) rotating on a circular path. Each rotatable knife (22, 32) is assigned a separate motor drive (26, 36) effecting the respective rotation. For each motor drive (26, 36) there is a dedicated controller, in which reference rotational positions can be stored.
