ABSTRACT:
A cutting and transport roller for material webs includes media outlet openings in its peripheral surface to which varying pressure can be applied to control the seating pattern of the material web on the peripheral surface of the roller. The roller has a system of pressure feed lines by which the media outlet openings are connected to means for supplying the media. The roller has at least one pressure reservoir that is a part of the pressure feed line system and that can be connected by a valve to at least one part of the media outlet openings.
