Abstract
To permit, selectively, positive feed or demand feed of yarn or thread to a utilization position of a textile machine, a rotating drum has a storage winding place thereon. A thread guide element is located laterally next to but below lower edge structure of the thread supply drum to permit drawing-off of yarn on the positive feed condition and preventing reverse winding of thread or yarn on the drum; additionally, a pull-off element is located either fixed, or rotatably about the axis of rotation of the drum in a plane which includes the axis of rotation of the drum below the bottom edge structure so that the thread or yarn can be selectively guided in a path inclined downwardly inclined exteriorally through the thread guide element 19 over the edge of the thread supply drum on in a different thread path over the pull-off element and then through the thread guide element.
