Abstract:
1. A process for winding up POY polyester filaments to form a package at winding speeds of at least 4,200 m/min by the arriving filaments being fed to a traversing yarn guide, being laid over the traverse length of the package and being redirected by a driven feeler roll which bears with a mandated contact force against the surface of the package which sits on a driven mandrel, wherein it comprises feeding the filaments to be wound up to the traversing filament guide at a relatively high yarn tension between 0.03 cN/dtex and 0.20 cN/dtex, operating the feeler roll at a higher surface speed than the package surface speed, setting the angle of wind between 3.50 and 7.50 degrees throughout the package, and setting the contact force of the feeler roll between 8 kg and 18 kg.
