摘要
Disclosed is a method and an apparatus for manufacturing an even laminated product by extruding 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 absorbing material to keep the said edge strips of coating material from adhering to the basic-material track. The edge strips of each track are then cut off said tracks, chopped separately, and directed separately for recovery.
