摘要

Flat bodies can be orientated between oppositely moving plane surfaces while contained by rollers therebetween. Cylindrical bodies are treated between oppositely rotating cylindrical surfaces, disc-like bodies between disc-like surfaces which are oppositely rotated. The motion serves to orientate the long chain molecules. The bodies are cooled while being orientated.
