Abstract

This invention relates to an inflation film producing apparatus which an air ring is provided at a position above a molding die so as to surround a circular slit and cooling air is blown from the air ring to the outer periphery of a tube-like molten synthetic resin which is extruded from the circular slit of the molding die, cooling the tube-like molten synthetic resin to produce a tube-like film. A spiral cooling air flow path is formed between a cooling air intake opening of the air ring and a circular cooling air blow-out opening. The cooling air with a uniform volume and speed in a circumferential direction is blown from the circular cooling air blow-out opening to the outer periphery of the tube-like molten synthetic resin. In the circular flow regulating member, a plurality of heating means which can be individually adjusted in temperature are disposed in a circumferential direction separated with specified interval between two adjacent heating means, to control the cooling air temperature blown to the tube-like molten synthetic resin in a circumferential direction.
