  • 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.

  • Publication number: 20100047648
    Abstract: A method of manufacturing a hydrogen separation membrane with a carrier is characterized by including a first step of providing, between the hydrogen separation membrane and the carrier that supports the hydrogen separation membrane, a low-hardness metal membrane having a hardness that is lower than the hardness of the hydrogen separation membrane, and a second step of joining the hydrogen separation membrane, the low-hardness metal membrane, and the carrier by a cold joining method. In this case, it is possible to suppress the deformation of the hydrogen separation membrane, the low-hardness metal membrane, and the carrier and, as a result, it is possible to prevent damaging of the hydrogen separation membrane. The adhesion of the contact between the hydrogen separation membrane and the carrier is also improved. The result is that it is not necessary to increase the severity of the cold joining conditions.
