Abstract

A continuous process and apparatus for the production of melt-spun monofilaments having a diameter of 60 .mu.m to 2500 .mu.m from fiber-forming polymers, wherein the polymer melt is spun into air from a spinning head, laterally quenched in a spinning cabinet with a defined air velocity profile and then cooled in a liquid bath.
