PURPOSE:To make a whole belt uniform, while the step at the end of the wind- initiation of a film is removed in a film-laminating belt. CONSTITUTION:While an engineering plastic film 12 is coated with the solvent dissolving the film 12 or the polymer solution 15 in which the polymer of the same material as the plastic film is dissolved in the solvent, the plastic film is wound into a plurality of layers. The solvent is dried and the endless flat belt made integrally is formed. The step at the end 12A of the wind-initiation of the film 12 is coated with the polymer-solution 14 into which the same polymer as the engineering plastic is dissolved, and the step is leveled out. |
