Abstract
A continuously operable chipboard press has a heatable pressing drum enclosed over a part of its periphery by a first endless steel pressing belt which is guided around direction-changing rolls, thereby forming a pressing section for a chip cake. In order to increase the surface pressure applied by the endless pressing belt, a second endless steel pressing belt is guided around separate direction-changing rolls within a space between the pressing section and a return pass of the first endless pressing belt. The second endless steel pressing belt acts on the outer face of the first pressing belt for a part of the pressing section.
