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.
Claims11
Thread supply apparatus for positive thread supply, for use with textile machines, comprising
- a support frame (8, 14);
- a rotatable yarn supply storage drum (1) journalled in the support frame for rotation in a clockwise or counter-clockwise direction.
- means supplying yarn to said drum (1) to form a stack of supply windings (27) thereon, the yarn being drawn off over the end of the drum from a pull-off position;
- a thread break sensor (28) in the path of the yarn and engaged thereby;
- a depending arm (14) extending from said frame and adjacent said drum and stationary thread guide means (15) at the end thereof beneath the drum and offset from the axis of the drum;
- and a thread guide element (23) including a pin-like finger (33) which is located below the drum (1) in the path of the thread adjacent the pull-off position, and upwardly of the thread guide means (15) and extends in a direction substantially parallel and laterally offset, with respect to a plane containing the axis of rotation of the drum and said guide means (15).
