Abstract

Process for the granulation of thermoplastic polymers, characterized in that a viscous strip is formed with the polymer from which the outer surfaces solidify, while retaining a pasty vein between the two solid films formed, said strip is printed with deep grooves at least according to two different directions, which gives rise to the formation of grains maintained together by a reduced thickness of polymer, which, finally, separate.
