  • Patent number: 4328929
    Abstract: To prevent kinks or twists formed upon uncontrolled removal of yarn from a storage drum from interfering with yarn withdrawal from the storage drum, an intermediate yarn guide element 20 is located between the lower edge 18 of the storage drum and the pull-off guide eye and is formed with at least one yarn guide edge located laterally with respect to the axis of rotation 24 of the drum 1 and in the path of the yarn from the storage winding to the removal guide eye. The yarn guide edge is extended to terminate into an elongated narrow guide slot 23 extending from the guide edge inwardly towards the axis of rotation of the drum.
