ABSTRACT:
A method of extruding thermoplastic resin by use of an extruder, wherein the thermoplastic resin is continuously passed through a compression moderating type resin feeding-melting section, a resin flow disturbing section and a resin stress relaxing section, and extruded through a die. In an apparatus for working this method, a helical screw of the extruder is provided with the resin feeding-melting section, the resin flow disturbing section and a transfer section for relaxing the resin stress.
