Abstract

To permit ready reversal of rotation of a yarn supply drum, and to positively guide yarn being drawn off the drum, a thread guide element in form of a finger is located laterally offset with respect to the axis of rotation of the storage drum, extending essentially in a direction transverse to a tangential plane at the pull-off point of the yarn, the lateral offset being changeable to either side of the pull-off point to accomodate different directions of rotation of the drum, with simple change-over of the yarn guide finger, for example by re-positioning a mounting plate to extend either towards the left or the right from a support arm.
