Abstract

Procedure for the continuous production of compressed or deformed polyurethane plastic foam products, starting from products necessary to obtain said foam product, characterized in that an intimate mixture of the products is carried out near a spraying or pouring device, spraying, said mixture being sprayed, poured or spread on a provisional or permanent support, providing a relative speed between the mentioned device and said support, determined as a function of the flow rate of the mixing device in order to obtain a determined thickness of foam products; the mass thus obtained is subjected to preparatory conditioning and said conditioned pot is subjected to a pressure effect, in such a way that the cellular texture of the material is permanently modified to obtain a final product that is totally or partially compressed or deformed.
