Abstract

PURPOSE:To extrude molten resin uniformly on the surface of a profile product such as glass-run and to coat it with the moltem resin by a method wherein the molten resin is extruded downward from an orifice provided between a scraper and an extrusion die while the thickness of the film is being adjusted. CONSTITUTION:A profile product 9 on which resin is to be coated is supplied to a guide hole 30 provided by a guide roller 27 having an uneven peripheral surface fitting to the shape of the lower surface of the profile product 9 (e.g. glass-run) and by a plurality of scrapers 15, 16, 17, molten resin is extruded under pressure downward from the orifice 25 provided between the scrapers 15, 16, 17 and the extrusion die 13 to provide a coating film 11 on the surface of said profile product 9. Beside, the thickness of the coating film 11 is adjusted by vertical movement of the scraper. The extrusion coating is conducted while the sectional form of the product 1 is maintained and a uniform film 11 is obtained.
