  • Patent number: 4313576
    Abstract: Several yarn packages or yarn reels are simultaneously wound on the same spindle using an improved process and apparatus, especially with regard to the start-up of the winding including the attachment of the yarns to the spindle and the formation of a yarn transfer end. Means are provided for engaging and disengaging the yarns from yarn reciprocating distribution guides which lay down the yarns on the rotating yarn reel. The same means in the form of a guide ramp guides the yarns from a common hooking point attaching the yarns to the spindle and then disengages from the yarns so that the yarns will be contacted for reciprocation over the main winding zone of the yarn reel by the reciprocating distribution guides.
