Abstract:
A method for producing a laminate, comprising the steps of:coating a surface of a running substrate with a film of thermoplastic resin extruded in a molten condition from an extruding die; and nipping the substrate and the film together between a nip roller and a cooling roller to produce a laminate while replacing, with a gas blown from a blower placed near the extruding die, air in an area where the nipping is conducted, wherein before the thermoplastic resin is extruded from the extruding die, a volatilization temperature of a volatile component of the thermoplastic resin is determined and the blower is heated at a temperature not below the determined volatilization temperature, wherein the blower blows the gas which has a temperature which is not above the temperature of the blower itself, and wherein the blower and the gas separately are heated by respective heaters.
