发明名称 Method and apparatus for manufacturing metallic sheet covered with thermoplastic resin
摘要 It is an object of the present invention to provide a method of and an apparatus for manufacturing a resin coated metal sheet, in which it is possible to reduce bubbles included between a laminated resin film and a metal sheet even when a thermoplastic resin film is laminated onto a web-shaped metal sheet even at high speed, and the laminated resin film is excellent in formable adhesion. The method of manufacturing a resin coated metal sheet comprises the steps of heating a web-shaped metal sheet (1), which advances continuously, supplying a thermoplastic resin film (5), which is heated to below a softening temperature of the thermoplastic resin film and to at least a surface temperature of a lamination roll (7), to a nip of the lamination rolls while maintaining the thermoplastic resin film at a higher temperature than the surface temperature of the lamination roll (7), and pressure-welding the metal sheet (1) and the thermoplastic resin film (5) against each other to laminate them.
