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. The intermediate yarn guide element is provided with a loop or kink deflecting element and comprises a re-entrant structure extending approximately parallel to and below the yarn guide element 20. In this loop deflection element 29 a narrow longitudinal slot 40 is formed which merges into the narrow guide slot 23 of the intermediate yarn guide element so that there are two slots present, one above the other, through which the yarn is passing. A movable sensing element for effecting stop-motion is provided.
