Abstract
A twisting machine for twisting several filament yarn strands which are preferably an aramid (aromatic polyamide) and wound on spools, has a creel for supporting the spools, a delivery system which includes several feed rollers, and a first thread guide which is supported before the delivery system along the strand paths for movement back and forth in directions parallel to the axes of the delivery rollers. The first thread guide is a cylindrical first guide roller which has a circumferential guide groove for each yarn strand and is rotatable about an axis which extends parallel to the feed roller axes. A second cylindrical guide roller is arranged following the delivery system along the strand paths, is freely supported for rotation about an axial movement along an axis which is parallel to the feed roller axes, and has a circumferential guide groove for each yarn strand. A spindle for supporting the winding bobbin is provided, and along an extension of the spindle axis a second thread guide is provided which has a guide eyelet for each yarn strand. Below the second thread guide is a third thread guide having an opening through which all the yarn strands are guided.
