ABSTRACT:
A rotary cutting device for material webs consists of a machine frame with rollers supported in pivot bearings on the machine frame, driven by rotary drives and defining a cutting range, namely a cutting roller and a counter cutting roller, which form a roller gap for feeding the web material between them within the cutting range. The cutting and counter cutting rollers are supported so as to roll directly one over the other using spacing rings located outside the cutting range. At least one of these rollers engages at least one adjustable pressure roller link bar between the spacing rings so that the link bar presses one roller against the other roller with an adjustable force.
