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...

A medical dressing (10) comprising an embossed, thin polymeric film coated (11) on one side with a medical grade, pressure-sensitive adhesive (16). The embossed film (11) has a low coefficient of friction, preferably less than about 0.6, on the outer adhesive free surface which makes the film particularly resistant to unintentional removal by rubbing forces. The film is intended primarily for use ...
