- a first counter-cylinder cooperating with said cutting and conveying cylinder and defining a first cutting gap through which a first web conveying path extends;
- at least a first cutting blade on said cutting and conveying cylinder and being usable for cutting off a first product from a first web of material in the course of passage of said at least first cutting blade through said first cutting gap;
- a first backstop on said first counter-cylinder and cooperating with said at least first cutting blade in said first cutting gap;
- a holding device on said cutting and conveying cylinder adapted to hold the first cut-off product and to convey the first product through said first cutting gap;
- and
- a second counter-cylinder cooperating with said cutting and conveying cylinder and defining a second cutting gap through which a second web conveying path extends, said at least first cutting blade being usable for cutting off a second product from a second web of material in the course of passage of said at least first cutting blade through said second cuffing gap.
