Abstract

A sheet of organic polymer capable of molecular orientation is passed with contact under pressure at a temp. below its crystalline fusion point, or a foil of such a polymer is passed at a temp. above its crystalline fusion point, through the interstice formed between two rolls turning in opposite directions and having a rough surface. At least one roll has several parallel, closely-spaced ridges each one having sides directed inwards leading to a peak, while the sides of adjacent ridges form troughs. The profiled sheet is cooled if necessary during and/or after contact with the rolls at a temp. below the crystalline fusion point of the polymer. Particularly fine polypropylene fibres for carpets, safety belts, ropes.
