The invention relates to a method for producing composite bodies consisting of at least one covering layer (4) and a rigid foamed material (5) based on isocyanate, the covering layer (4) being continuously moved and the starting material for the rigid foamed material (5) based on isocyanate being applied to the covering layer (4). The invention is characterised in that the application of the liquid starting material for the rigid foamed material (5) based on isocyanate is carried out by means of a fixed tube (3) provided with boreholes and oriented towards the covering layer (4) in such a way that it is parallel and at a right angle to the direction of movement.
L'invention concerne un procédé de fabrication d'éléments composites composés d'au moins une couche de couverture (4) et d'une mousse dure (5) à base d'isocyanate, la couche de couverture (4) étant déplacée en continu et le matériau initial de la mousse dure (5) à base d'isocyanate étant appliqué sur la couche de couverture (4). Le procédé est caractérisé en ce que l'application du matériau initial liquide de la mousse dure (5) à base d'isocyanate est réalisée au moyen d'un tuyau fixe pourvu (3) de trous percés, disposé parallèlement et à angle droit par rapport à la direction de déplacement de la couche de couverture (4).
