Abstract

A process for the production of polyurethane foam from a mixture of reactants, comprising the steps of passing the reactants along a conveyor as they react to produce the polyurethane foam and enclose the reaction material in the conveyor by lateral surfaces that move along with the material; introducing a coating material between said lateral surfaces and the reaction material moving the coating material along the conveyor and upward with the ascending foam so that the upper surface of the foam remains flat and continue to move the material of coating along the conveyor in contact with the foam after it has ceased to rise.
