Abstract
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 (,), which advances continuously, supplying a thermoplastic resin film (,), which is heated to below a softening temperature of the thermoplastic resin film and to at least a surface temperature of a lamination roll (,), 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 (,), and pressure-welding the metal sheet (,) and the thermoplastic resin film (,) against each other to laminate them.
