Abstract

Oriented continuous yarns are produced from synthetic thermoplastic by melt-spinning monofilaments which are taken off, cooled and wound up without the use of a godet roll at velocities of more than 2500 meters per minute. The monofilaments are combined in a bundle after the cooling zone which is then toted and moved through at least one vertically adjustable guide before it is wound up.
