    摘要: A thermoplastic resin film manufacturing method and manufacturing device are disclosed wherein an air volume sprayed by the auxiliary cooling device onto the surface of the film on the opposite side thereof to the cooling drum side thereof is set to be larger than the suction amount by an exhaust mechanism between nozzles, to avoid the suction of the air containing the high concentration of oligomer around the extrusion die into the auxiliary cooling device, thereby preventing precipitation and deposition of the oligomer onto spraying nozzles within the auxiliary cooling device and the suction surface of the exhaust mechanism between nozzles.
