For applying a surface pressure and temperature to pressing band-driven workpieces a fluid pressure medium is accommodated in a pressure chamber which is limited between a pressing band and a workpiece as well as seals located therebetween, and the fluid pressure medium is subjected to extensive forced movement in the pressure chamber which forms an action zone.

Arrangement for applying a surface pressure to workpieces driven by a

An arrangement for applying a surface pressure to continuously moving workpiece webs, such as laminates, having at least one movable pressing band arranged to be pressed against a workpiece web by a pressure medium, a pressure chamber with a supply side and a discharge side so that the band is movable in a direction from the supply side into the pressure chamber to be heated and softened and then to be cooled and hardened and then it moves further in the movement direction to the discharge side. The arrangement has a sealing frame with a contour defining an enclosed region and is pressure loaded in a direction toward the pressing band. A transverse frame portion located at the discharge side has a smaller width than a transverse frame portion at the supply side.

Arrangement for applying surface pressure to continuously moving

A device for applying surface pressure to a movable workpiece, for example a plate of wood, comprises two pressure-applying endless belts on which pressure is exerted by means of pressure air contained in two pressure chambers. Each pressure chamber is defined by a back side of the belt, a pressure plate and a sealing provided on the pressure plate. The sealing includes longitudinal wave-shaped sealing strips extended along the longitudinal edges of the pressure plate and transversal strips.
