A method for processing a coated or uncoated fibrous web

摘要

The invention relates to a processing device for processing a coated or uncoated fibrous web, comprising a belt (2) adapted to extend around at least one guiding element (3), at least one counter-element (5) being disposed outside said belt to provide a contact area with the belt, such that the belt (2) and the counter-element (5) establish therebetween a web processing zone for passing a web to be processed therethrough, wherein
the processing zone length is defined by means of the disposition/adjustment of the belt's (2) guiding element (3) and/or by means of the design of said at least one counter-element (5), and that a contact pressure applied to the web in the processing zone is adapted to be adjustable within the range of about 0.01 MPa to about 200 MPa, and that
the roll (5) comprises a thermal roll, that the belt (2) comprises a metal belt, and that the operating temperature of the thermal roll (5) and/or the metal belt lies within the range of about -70°C to about 400°C, and
the belt comprises a metal belt, having a thickness of about 0,1 to 3 mm.
