Abstract

L'invention se rapporte à la fabrication d'articles composites. Elle concerne un procédé pour revêtir d'un polymère thermoplastique un substrat 2 en forme de plaque, selon lequel on extrude du polymère fondu entre une première et une deuxième lèvres d'une filière et sur une face du substrat, la filière étant formée en partie d'un bloc métallique 5 muni de moyens permettant de faire arriver du polymère fondu aux lèvres de filière, caractérisé en ce que l'on fait avancer le substrat en contact face à face avec le bloc métallique, on fait passer ce substrat de sa position de contact avec le bloc à une position espacée de la première lèvre 13, le substrat formant ainsi la deuxième lèvre de la filière, et on extrude du polymère fondu dans l'espacement entre la première lèvre de la filière et le substrat de façon à revêtir celui-ci de polymère 20. Les plaques revêtues sont utiles pour la construction.The invention relates to the manufacture of composite articles. It relates to a process for coating a substrate 2 in the form of a plate with a thermoplastic polymer, according to which molten polymer is extruded between a first and a second lips of a die and on one side of the substrate, the die being formed in part. of a metal block 5 provided with means allowing molten polymer to arrive at the die lips, characterized in that the substrate is advanced in face to face contact with the metal block, this substrate is made to pass from its position contact with the block at a position spaced from the first lip 13, the substrate thus forming the second lip of the die, and molten polymer is extruded into the space between the first lip of the die and the substrate so as to coat Polymer 20 thereof. Coated plates are useful in construction.
