Abstract
Methods and apparatus are disclosed for restrained paper drying in order to produce high performance paper with enhanced stiffness and, in the process, substantially improve paper properties and reduce fiber usage. The paper web is held in a restrained position on a fabric by air suction imposed from beneath the web and is of sufficient application to prevent shrinkage of the web. The web is simultaneously dried by high velocity, high temperature air or superheated steam. For improved finish properties, the wet paper web may be pressed onto a polished heated metal cylinder with restraint being imposed by gluing.
