摘要： A process for producing a multilayered unstretched film. The process is intended to minimize the amount of those thick parts of a film formed which are to be discarded, and to thereby attain a cost reduction. Thermoplastic resins (20A) and an extra thermoplastic resin (20B) different from the thermoplastic resins (20A) are separately melted by heating. Immediately before widening in respective manifolds, the extra thermoplastic resin is introduced to each edge part of each of the objective thermoplastic resins. The resins are fed to and widened in the manifolds so that the extra thermoplastic resin is disposed on the side of each edge of each objective thermoplastic resin. Subsequently, the melts are joined and ejected from the die lip of the T-die on a casting roll. Thus, a multilayered unstretched film is formed which comprises multilayered thermoplastic resins made of the objective thermoplastic resins and the multilayered extra thermoplastic resin disposed on the side of each edge of those multilayered resins. Thereafter, the parts constituted of the extra thermoplastic resin are removed by cutting to form a multilayered unstretched film (20) consisting mainly of the objective thermoplastic resins.

摘要： [Problem] The present invention provides a manufacturing method and apparatus of an organic resin coated metal sheet which can surely remove resin portions projecting from both edges of a metal sheet.[Means for Resolution] A long strip metal sheet 1 is continuously fed using a metal-sheet supply means 13. Temperatures of edge portions 1a, 1b of the metal sheet 1 and a temperature of an approximately central portion 1c of the metal sheet 1 are respectively measured using a metal-sheet temperature measuring means 7 arranged directly upstream of lamination rolls 10. Respectively measured temperature values are inputted to a heating temperature control means 14. An output value calculated by the heating temperature control means is inputted to a metal sheet center portion heating means 3 arranged directly upstream of the T-die 8 so as to heat a widthwise approximately center portion of the metal sheet 1 to a first temperature by the metal sheet center portion heating means 3. Output values calculated by the heating temperature control means 14 are fed to metal sheet edge portion heating means 5 arranged directly upstream of the T-die 8 so as to heat the widthwise edge portions of the metal sheet 1 to a second temperature higher than the first temperature by the metal sheet edge portion heating means 5. A resin film is extruded to pre-rolls 9 such that the resin film projects from both widthwise edge portions of the metal sheet 1. The resin film is applied to the metal sheet 1 by sandwiching and pressure-bonding the metal sheet 1 and the resin film between a pair of lamination rolls 10. Resin portions 2a in a semi-molten state and projecting from both edge portions of the metal sheet are removed by press cutting.

摘要： 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.

摘要： The present invention provides particularly, in a method of manufacturing an organic resin-coated metal sheet by an extrusion lamination method, a method of removing an oligomer adhered to a roll with which a heat molten resin comes into contact while removing an oligomer and an apparatus of manufacturing an organic resin-coated metal sheet. In a manufacturing method of an organic-resin coated metal sheet which includes the steps of: continuously extruding an organic resin in a molten state by heating from a T-die in a film shape onto an elongated strip-shaped metal sheet; dropping a molten resin on pre-rolls arranged between the T-die and lamination rolls and bringing the molten resin into contact with the pre-rolls; and pressing the molten resin and the metal sheet by lamination rolls thus manufacturing the organic-resin coated metal sheet, an oligomer removing method is characterized in that electric 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 electric conductive bodies at predetermined intervals thus bringing the molten resin into contact with surfaces of the pre-rolls by electrostatic pinning whereby an oligomer adhered to the pre-rolls is transferred to a surface of the molten resin and is removed.
摘要翻译：本发明特别提出了通过挤出层压法制造有机树脂被覆金属片的方法，除去附着在与熔融树脂接触的辊的低聚物和除去低聚物的方法制造有机树脂涂覆的金属片。在有机树脂被覆金属片的制造方法中，包括以下步骤：通过从薄膜形状的T形模加热而将熔融状态的有机树脂连续挤出到细长的带状金属片上; 将熔融树脂滴在布置在T形模和层压辊之间的前辊上，并使熔融树脂与前辊接触; 并通过层压辊压制熔融树脂和金属片，由此制造有机树脂涂覆的金属片，低聚物除去法的特征在于导电体平行于前置辊的宽度方向设置，熔融树脂以预定间隔向导电体供给电流的状态下落在前贴片上，从而通过静电锁定使熔融树脂与前贴片的表面接触，由此使粘附到前贴片的低聚物转移到熔融树脂的表面并除去。
