Japanese Patent JP2005516133

A

The invention relates to a processing device for processing a coated or uncoated fibrous web, comprising a belt (2) adapted to extend around a guiding element (3), at least one roll (5) being disposed outside said belt to provide a contact area with the belt, such that the belt (2) and the roll (5) establish therebetween a web processing zone for passing a web to be processed therethrough, wherein outside the belt (2) is provided a deflection-compensated nip roll (26) to establish a profiling nip with the roll (5), a web (W) being adapted to travel through said profiling nip, that 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 dimensioning of the roll (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 50°C to about 400°C, and the belt having a thickness of about 0,1 to 3 mm.
