Abstract
To prevent formation of kinks or twists upon uncontrolled removal of yarn from a 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, the intermediate yarn guide element 20 being 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 formed in the intermediate yarn guide element, the slot extending from the guide edge inwardly towards the axis of rotation of the drum. A movable yarn sensing element 30 is located in a position between the yarn guide edge 25 and the yarn removal guide eye, and biased for movement of the yarn towards the axis of rotation of the drum, and moved counter its bias by the tension of the yarn passing thereover and being pulled off, the sensing element effecting stop-motion of the machine upon loss of tension and additionally guiding the yarn into the narrow guide slot which prevents kinking, or uncontrolled looping thereof.
