  • Patent number: 3973739
    Abstract: A high-speed winding apparatus for producing a filamentary spool package on a spool sleeve including spool holder means which engages the spool sleeve and which is rotatably mounted by means of a first set of anti-friction bearings onto a spool carrier which in turn is rotatably mounted by means of a second set of anti-friction bearings onto a support member. Drive means are provided to at least rotatably drive said spool holder means either directly or by a friction roll contacting the cylindrical surface of the spool package. The spool carrier is preferably also driven by a common or separate drive means at rotational speed proportionately slower than said spool holder means. The apparatus is especially useful for the take-up winding of filaments, threads, yarns or the like as employed in spin-drawing and high-speed spinning machines requiring linear winding speeds in excess of 5,000 meters/minute and spool revolutions of more than 30,000 rpm.
