Abstract
A processing device and method applying the same for processing a coated or uncoated fibrous web is provided. The device comprises a belt configured to extend around a guiding element, at least one counter-element being disposed outside said belt to provide a contact area with the belt, such that the belt and the counter-element establish therebetween a web processing zone for passing a web to be processed therethrough. The processing zone length is defined by the disposition of the belt's guiding element and/or by the configuration of the counter-elements. The contact pressure applied to a web in the processing zone is within the range of between about 0.01 MPa and about 200 MPa.
