Abstract

Abstract Translated from German Bei einer Vorrichtung zum Aufbringen einer Flächenpressung auf fortschreitende Werkstücke wie Holzwerkstoffplatten (14) mittels eines umlaufenden Pressbandes (12), das mittels eines Druckmittels gegen das Werkstück anpressbar ist, ist dieses Druckmittel jeweils in eine Vielzahl von versetzt angeordneten Druckkammern (17,25,32,46) einer Tragplatte (20,33,43) einleitbar, welche auf das Pressband (12) einwirken. Dabei sind die Druckkammern (17,25,32,46) von Dichtungen (35,45) gebildet, die jeweils von einer inneren Fassung (36,37) gehalten und in einer äußeren Fassung (38) bzw. in einer Nut (44) abgedichtet höhenverschiebbar geführt sind. In the case of a device for applying surface pressure to progressive workpieces such as wood-based panels (14) by means of a rotating press belt (12) that can be pressed against the workpiece by means of a pressure medium, this pressure medium is in each case in a plurality of staggered pressure chambers (17,25,32 , 46) of a support plate (20, 33, 43) which can act on the press belt (12). The pressure chambers (17,25,32,46) are formed by seals (35,45), each of which is held by an inner socket (36,37) and in an outer socket (38) or in a groove (44) sealed are guided vertically.
