The invention relates to an assembly for pressing pressing parts, especially those that are made out of wood, into large elements by means of a pressing unit, a pressing table, and a counter-pressure plate which is characterised in that the counter-pressure plate (9) functions as a pressure-absorption plate (9) which is designed so as to be heavyweight but resistant to bending as well as twisting and features pressure elements (14) which are facing the pressing parts. Said pressure-absorption plate (9) features roller carriers (93) which, horizontally distanced (ha) to each other, are located on its longitudinal lateral flanks (92) and ~ with said carrier rollers (93) ~ is movable at the same horizontal distances (ha) on the guide rails (101) which are connected to the frame carrier (10) of the pressing unit (6) and are designed so as to be at a maximum angle of 30° relating to the main extensions of the pressing table (13) as well as parallel and linear ~ and by the use of drive (96), its height can be adjusted by means of moving on the guide rails (101). Preferably, the pressure-absorption plate (9) with the locking wedge (95) which are designed as to have the same horizontal distances ~ the wedge angle (.beta.) corresponding to the rising angle of the guide rails (.alpha.) ~ is constructed in such a manner that the locking surface (952) which is facing the lower side of the guide rails (102) wedge in friction during the introduction of pressure to the pressure elements (14).

La présente invention concerne un nouvel ensemble destiné à comprimer des pièces embouties à la presse, en particulier en bois, pour obtenir des éléments de grande taille, comprenant une unité de presse, une table de presse et un plateau de contre-pression, caractérisé en ce que le plateau de contre-pression (9) est conçu en tant que plateau d'absorption de pression (9) lourd, résistant à la flexion et à la torsion, équipé, du côté de la matière à presser, d'éléments de pression (14) tournés vers la matière à presser, lequel plateau présente le long de ses flancs latéraux (92) des rouleaux porteurs (93) disposés à des intervalles horizontaux les uns des autres, et en ce qu'il est mobile grâce à ces rouleaux porteurs (93) sur des rails de guidage (101) linéaires disposés de manière parallèle et oblique d'un angle (a) de 30° maximum par rapport à l'extension principale de la table de presse (13) et liés à la poutre cadre (10) de l'unité de presse (6), et en ce qu'il est réglable en hauteur au moyen d'un mécanisme d'entraînement (96) correspondant grâce au déplacement sur les rails de guidage (101), le plateau d'absorption de pression (9) étant équipé de clavettes de blocage (95) disposées à intervalles horizontaux réguliers, avec des surfaces de blocage (952) tournées vers la surface inférieure des rails de guidage (102) et présentant un angle de cale (ß) correspondant à l'angle de montée des rails de guidage (a) pour un calage par friction pendant l'application de pression sur les éléments de pression (14).
