Abstract
Process for the continuous production of polyurethane foam materials in the form of blocks or combined polyurethane foam materials by reaction of polyols with polyisocyanates in the presence of propellants and additives and, optionally, catalysts and chain extension or crosslinking agents between sheets bands, characterized in that the reaction mixture that leaves the mixing chamber of a block foaming machine is let out through a tunnel, whose sides, ceiling and bottom are covered with sheets of polyurethane foam material, which are moved synchronously with the conveyor belt of the sputtering machine in blocks from the mixing head.
