Abstract

A laminating roll which, when used in producing an organic-resin-coated metal sheet by the extrusion method, is free from a trouble that a resin part (fin part) protruding from the metal sheet winds around the shaft of the laminating roll. The laminating roll enables an organic-resin-coated metal sheet to be continuously and stably produced. The laminating roll has a region lined with a lining material, the width (A) of the lined region and the width (B) of the metal sheet satisfying the relationship 0=A-B=20 mm. The metal sheet is coated by extrusion with a thermally melted organic resin so that width-direction edge parts of the organic resin protrude from the edges of the lined region in the laminating roll. Thereafter, the resin part in a semi-molten state which protrudes from each edge of the metal sheet is removed by press-cutting.

Description

technical field [0001] The present invention relates to a method of manufacturing a metal plate covered with organic resin. Background technique [0002] Currently, when manufacturing a metal plate covered with an organic resin, a thermoplastic resin is heated and melted in an extruder, and a film is ejected from a T-die, extruded and covered on the metal plate. In the process of manufacturing the metal plate covered with organic resin by the extrusion method, the film-like molten resin discharged from the T-die has the characteristics of a high-viscosity molten resin, that is, the thickness of the film at both ends is greater than that of the central part, so the film-like When the molten resin is extruded on the metal plate, the entire area in the width direction of the metal plate is covered with a uniform thickness of the molten resin, and after extrusion, the molten resin part thicker at both ends than the center part overflows from the width direction of the metal plat...
