<p>PURPOSE:To eliminate occurence of curling and remaining of solvent, and improve productivity by preparing laminated film, and providing a removing process of film for peeling off of polypropylene or the like. CONSTITUTION:In a first process, a hot melt adhesive is applied to the one side surface of film for peeling off of polypropylene or the like and dried, and polyvinyl chloride film is bonded to the adhesive surface by thermo-compression bonding so as to prepare laminated film. In a second process, an adhesive is applied to the one side surface of polyester film or fluororesin film and dried, and the polyvinyl chloride film side surface of the laminated film obtained in the first process is superimposed on the adhesive surface and thermo- compression bonded so as to remove the film for peeling off of polypropylene or the like. Thereby it is possible to reduce the number of processes, increase manufacturing speed, and improve productivity comparing with an usual coating method, and a flat wire having high adhesive strength can be obtained since an obtained sheet is free from curling and remaining solvent.</p> |
