Extruder Seal Abstract of the Invention An extruder machine for processing of plastic materials, rubber or polymers in which a stationary casing is provided with a generally tubular bore having an inlet opening near one end thereof, and a discharge opening at the other end thereof. A generally cylindrical rotor is rotatably mounted in the bore of the casing. The casing is comprised of a pair of generally coaxially aligned spaced apart cylindrical members, having a length substantially longer than their diameters. A heating or cooling fluid is passed in the spacing be- tween the cylindrical members in a heat transfer relationship. Each pair of cylindrical members is provided with expansion/contraction joints to permit longitudinal expansion or contraction of the compon- ents with respect to one another. An annular flexible bellows seal is biasedly disposed within the spacing between the outer cylinder and the inner cylinder in a fluid tight relationship between the two to prevent leakage of cooling or heating fluid therefrom during periods of extruder operation.
