Abstract
A method and apparatus for manufacturing a resin coated metal sheet. The method includes extruding a molten organic resin by heating from a T-die onto a metal sheet; dropping molten resin onto pre-rolls arranged between the T-die and lamination rolls, and bringing the molten resin in contact with the pre-rolls; and pressing the molten resin and the metal sheet by the lamination rolls to manufacture the resin-coated metal sheet. Electrically conductive bodies are arranged parallel to the widthwise direction of the pre-rolls, and the molten resin is dropped onto the pre-rolls in a state that an electric current is supplied to the conductive bodies, bringing the molten resin into contact with the pre-rolls by electrostatic pinning whereby an oligomer adhered to the pre-rolls is transferred to the surface of the molten resin and removed.
