METHOD AND DEVICE FOR MANUFACTURING RESIN FILM WITH COATING FILM

摘要

PROBLEM TO BE SOLVED: To provide a method and device for manufacturing a resin film with a coating film capable of preventing overheating of an unapplied portion to which coating fluid is not applied when the coating fluid applied to the resin film is dried in a resin film manufacturing process.SOLUTION: A method of manufacturing a resin film with a coating film includes: a process A of applying coating fluid to a resin film that is being conveyed and forming an applied portion to which the coating fluid is applied with given thickness and a transition region that is formed between the applied portion and an unapplied portion having no coating fluid applied thereto, the transition region applied with the coating fluid with thinner thickness than that applied to the applied portion; a process B of applying overheating inhibiting fluid to at least part of the transition region and the unapplied portion so that the fluid is applied to a boundary portion between the unapplied portion and the transition region; and a process C of drying and solidifying the coating fluid on the applied portion and the transition region by heating and of drying the overheating inhibiting fluid by heating the overheating inhibiting fluid, so as to form the coating film on the resin film.SELECTED DRAWING: Figure 1
