Abstract

Un dispositif (1) et un procédé servent à fabriquer des dalles de couverture de toits ayant sur leur face intérieure une bride transversale intégralement façonnée par extrusion. Des cavités de demi-moules inférieurs (7, 7') correspondant à la bride transversale sont remplies dans une station de chargement (20) avec du matériau plastique durcissable qui est condensé ensuite dans une station de condensation (40, 60, 70), avant qu'une couche continue du matériau ne soit appliquée dans une station de revêtement (78). Le matériau est ensuite traité de manière connue afin de former des dalles de couverture de toits.
