Abstract of the disclosure Disclosed is a method and an apparatus for manufacturing an even laminated product by extrusion a molten thermoplastic coating material track onto a basic-material track. The edge strips of the coating material track are cooled by means of jets of heat binding material to keep the said edge strips of the basic-material track. The strips of each track are then cut off said tracks, chopped separately, and directed separately for recovery.
