Abstract

L'invention concerne une presse continue pour le pressage de mats de matière à presser pour obtenir des plaques de matière à presser, notamment pour fabriquer des plaques de matériau de bois. La presse comporte une partie supérieure de presse présentant une plaque de presse supérieure et une partie inférieure de presse présentant une plaque de presse inférieure, des bandes de presse en acier tournant sans fin dans la partie supérieure de presse et la partie inférieure de presse, ainsi qu'une structure de presse présentant une pluralité de cadres de presse fermés, disposés en rangée dans la direction longitudinale de presse. Des cylindres de presse actionnant la plaque de presse supérieure ou la plaque de presse inférieure s'appuient contre les cadres de presse. La presse est caractérisée en ce que les cadres de presse sont respectivement conçus en tant qu'éléments cadres coulés en métal coulé. Les cadres de presse sont de préférence conçus en tant qu'éléments coulés fabriqués en une seule pièce, de préférence en fonte ductile.
