Abstract
An apparatus for feeding a molten resin is operated for extended periods of time maintaining stability without permitting volatile components of the molten resin to adhere on the surfaces of conveyer means. An extruder in the apparatus for feeding the molten resin to the compression-forming machine has an extrusion unit which discharges a molten resin through an extrusion opening of an extrusion nozzle. An air injection nozzle for injecting the cooling gas is provided along the outer circumference of the extrusion nozzle, and the cooling gas is blown onto the surface of the molten resin extruded from the extrusion opening to cool the surface of the molten resin.
