  • Patent number: 8110244
    Abstract: A manufacturing method and apparatus of an organic resin coated metal sheet is provided. Temperatures of edge portions of the metal sheet and a temperature of an approximately central portion of the metal sheet are respectively measured using a metal-sheet temperature measuring device arranged directly upstream of lamination rolls. Respectively measured temperature values are inputted to a heating temperature controller, and output values calculated by the heating temperature controllers are inputted to a metal sheet center portion heater and the metal sheet center portion heater, respectively, to control the heating of a widthwise approximately center portion and edge portion, respectively, to a first and second temperature, respectively, the second temperature being higher than the first. A resin film is extruded to pre-rolls and is sandwiched and pressure-bonding to the metal sheet between a pair of lamination rolls. Resin portions projecting from both edge portions are then removed.

  • Patent number: 7985315
    Abstract: A process by which many kinds of unstretched films comprising a thermoplastic resin are produced each in a small amount and high yield. A thermoplastic resin (A) to be formed into an unstretched film and another thermoplastic resin (B) are separately melted by heating. The thermoplastic resin (B) is introduced to each edge part of a T-die (2) for extrusion. The two resins are ejected and extruded on a casting roll so that the thermoplastic rosin (B) is disposed on the side of each edge of the thermally melted thermoplastic resin (A). Thus, an unstretched film (20) is formed which comprises the thermoplastic resin (A) and the thermoplastic resin (B) disposed on the side of each edge of the resin (A). Thereafter, the parts constituted of the thermoplastic resin (B) are removed y cutting to form a target unstretched film (20) consisting only of the thermoplastic resin (A).

  • Patent number: 7815976
    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.

  • Publication number: 20100224314
    Abstract: The present invention aims at the continuous and stable production of an organic-resin-coated metal sheet in producing the organic-resin-coated metal sheet by an extrusion method using a laminating roll which can prevent resin portions (ear portions) protruding from the metal sheet being wound around shaft portions of the laminating roll. Using a laminating roll in which a width (A) of a region thereof coated with a lining material satisfies a relationship of 0?A?B?20 mm with respect to a width (B) of the metal sheet, a thermally melted organic resin is extruded and is applied to the metal sheet such that end portions of the organic resin in the widthwise direction protrude from outer portions of the laminating roll applied with the lining material, and the resin portions in a semi-molten state which protrude from respective edges of the metal sheet are removed by press-cutting.
