Abstract

PURPOSE:To obtain the titled sheet which can be shaped into any desired form and is from attendant strains by a method wherein a film form molten resin is shaped by shaping rolls in a liquid coolant, and it is completely cooled and solidified to its core part while moving it in a specified direction. CONSTITUTION:For example, the film form molten resin (e.g., a PETE base polyester or the like) P extruded through a slit form nozzle 2 of a die 1 is passed through a gap C between the shaping rolls 4, 4' immersed in the liquid coolant (usually, water at a temperature of 50 deg.C or lower is preferable) W containined in a liquid-coolant tank 3 to shape the resin P before it is cooled and solidified to its core part. Then, the film form resin P thus shaped is moved in the tangential direction in respect of a shaping point at the gap C of the rolls 4, 4', preferably in a no-tension or low-tension condition, to cool and solidify the resin P to its core part, followed by drawing out the sheet from the tank 3 by guide rollers 5, 5'. EFFECT:Thermal efficiency is high and the apparatus can be made compact.
