发明名称 EQUIPMENT FOR MANUFACTURING FILM
摘要 PROBLEM TO BE SOLVED: To surely remove residual water droplets sticking to an unstretched sheet after the sheet is subjected to a moisture conditioning treatment, on the occasion of manufacturing a plastic film. SOLUTION: The present manufacturing equipment 14 has an extruder 4 which extrudes a molten thermoplastic polymeric compound 2 as the sheet 3 in an unstretched state, a cooling drum 5 which receives the sheet 3 extruded from the extruder 4 and cools it, a water tank 7 for applying the moisture- conditioning treatment to the sheet 3 cooled by the cooling drum 5 and a water removing device 15 which removes the water droplets sticking to the surface of the sheet 3 subjected to moisture-conditioning treatment in the water tank 7, while holding and pressing the sheet 3 between rollers thereof. Swelling portions 17a and 17b are formed in the respective central parts in the axial direction of the water removing rollers 15a and 15b constituting the water removing device 15.
