PURPOSE:To manufacture one or many kinds of composite sheets at a time, by a method wherein after many kinds of molded products have been molded by dividing a width of a metallic thin plate, to which emboss processing has been applied, and bent faces into a box type in a longitudinal direction are sealed by abutting against each other, foam raw materials are discharged, on which a backing material is put and fed to a curing oven. CONSTITUTION:Embossed patterns are formed continuously on a coil A of a metallic thin plate by an emboss roll 10. Residual strain is corrected by a leveller 11, a notch is formed on a predetermined position by a notch press and standard length cutter part 14 and cut off in standard lengths at the same time. The coil A is inverted, divided into (n) in a widthward direction by a dividing and cutting machine 24 located on the ground floor and (n) sheets of molded materials A'' are molded by a molding machine 25 at the same time. The cut ends of the molded material A'' in a longitudinal direction are bent by a box bending part 26 and bent faces (a) into a box type are sealed together. A molded belt A''' turned continuous belt is heated, onto a recessed part of which an unfoamed synthetic resin foam raw materials P are discharged through a discharge part 30, on which a backing material C is laminated, caulked to both ends of a molded material A''' and fed to a curing oven 35. Then the same is reacted, foamed and cut apart at the bent face (a) into the box type. |
