Abstract
PURPOSE:To prevent the neck-in of a polymer sheet quenchable under vacuum at a high speed, by bringing a molten polymer sheet extruded through a die under different pressures on both sides into contact with a quenching roll coated with a liquid. CONSTITUTION:One side of the molten polymer sheet (or film)4 extruded from the die 1 on the quenching roll 2 is exposed to the atmosphere of the vacuum chamber 3 connected to the exhaust pipe 6, and brought into close contact with the roll 2. A liquid applied to at least zones corresponding to the selvages of the sheet 4 by the applicators 5 sharply reduces both the neck-in of the sheet 3 and the spaces between the selvages and the sidewalls of the vacuum chamber 4 which cannot be easily sealed in vacuum. As a result, a high degree of vacuum is possible, and the variation of film width and thickness unecenness can be reduced.
