Abstract
Apparatus and method in which the temperature of the barrel inner surface and the temperature of the screw conveyor outer surface of a plasticating extruder are varied, alternately, in repeated steps, independent of one another along at least a portion of the solids conveying zone of the extruder, while a production effectiveness parameter simultaneously is monitored, until the monitored production effectiveness parameter is optimized and the production effectiveness of the extruder is at a desired maximum.
