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.

Abstract: A support structure having a beam portion (2) undergoing bending when the load is imposed on the support structure and a separate elastic member (1a) which deforms elastically in a manner inversely proportional to beam bending from the middle of the support structure towards its ends so that the sum of the deformation produced by beam bending and the deformation of the elastic member is constant, whereby a longitudinal support line in the support structure remains as a straight line even though the support structure itself yields in the direction of the force.
