Abstract

Procedure for obtaining continuous blocks of expanded polyurethane plane and with rectangular section; characterized by presenting a phase of discharge of the liquid material on a movable floor mold, a dragging of said material by means of said floor immediately starting the expansion in an area where the regulating rollers and distributors of the expansion of the foam will be placed, which will avoid the corona effect or formation of a dome, on its free surface; because it is foreseen the placement of a material separador of coating, between the referred rollers and the foam, which avoids that it stains to those, that its surface is oxidized and that the gases of foaming go out to the outside until they are used to the maximum, presenting a perforating device of said coating material to subsequently assist in the exit of the retained gases, with a system for attaching the coating material to the inner lining of the mold, as well as a heat-emitting system with which the total timing of the movement of the referred covering material and the foam.
