摘要： A method of producing a stretched film comprising melt-coextruding a thermoplastic resin A and a thermoplastic resin B to produce a composite film 1 having both-end films 2 of the thermoplastic resin B arranged in parallel at both end portions of the main film 1a of the thermoplastic resin A in the direction of width thereof, stretching the composite film, and cutting and removing both end portions of the stretched film in the direction of width, wherein a film stretch stress value of the both-end films 2 is larger than a film stretch stress value of the main film 1a at the same stretching ratio. This minimizes an increase in the thickness at both end portions of the film in stretching the film and decreases the widths by which both end portions of the expensive resin film are to be cut and removed for producing a film.

摘要： 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.

摘要： 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.
