Process and apparatus for preparing sheetlike article

Abstract

PURPOSE: To prepare a long-sized sheetlike article having uniform coated film continuously by feeding fresh layer of a reactive resin to form a spread face to a bank of the reactive resin just before a knife coater and forming a coated layer of the reactive resin on a substrate. CONSTITUTION: Reactive resin is fed and spread to form a face to the periphery of a bank B formed by scraping of the reactive resin just before a knife coater 7. The bank B is grown gradually by rotating while controlling the amt. of the fresh reactive resin to be fed. Thus, a layer of a coated layer of the reactive resin is formed on a substrate 2. By this method, generation of trace of charged resin due to the change of viscosity of the resin before it is coated on the substrate or unevenness of coating due to unevenness of coated amt. is prevented. Thus, a long-sized sheetlike article having a uniform and smooth coated layer is prepared continuously. COPYRIGHT: (C)1985,JPO&Japio
