PURPOSE:To dispense with a high temp. baking device and to prepare a fluorinated resin laminated sheet having thickness accuracy by arranging metal foils to the upper and lower surfaces of a laminate, wherein glass cloths are respectively interposed between a required number of fluorinated resin films, to perform press molding under heating. CONSTITUTION:Metal foils are arranged to the upper and lower surfaces of a laminate wherein glass cloths are respectively interposed between a required number of fluorinated resin films and subjected to press-molding under heating to prepare a fluorocarbon resin laminated sheet. Therefore, a high temp. baking apparatus is unnecessary and a resin thickness can be made constant and the thickness accuracy of the laminated sheet can be enhanced. The thickness of each fluorinated resin film is desirably 0.01-1mm and the film can be used one by one or two or more films can be used as one set. The disirable thickness of each glass cloth is 0.01-0.5mm and, as the metal foil, one composed of copper, iron, aluminum, nickel, zinc or the like alone, an alloy thereof or a composite product thereof can be used. |
