The second storage means includes an elongated hollow shaft having a stationary storage drum mounted thereon. The first thread storage includes a thread drum disposed adjacent and coaxial with the storage drum and rotatably supported on an extension of the hollow shaft. A winding element is associated with the storage drum for permitting winding of a thread thereon, which winding element is rotatably supported on the hollow shaft and disposed axially between the storage and thread drums. The thread withdrawn from the storage drum passes axially through the hollow shaft and is then wound onto the annular thread storage area of the thread drum. A drive device includes a driving element shiftable between two positions, the first being wherein the driving element engages solely the thread drum for rotating same. The driving element, when in the second position, simultaneously engages both the thread drum and the winding element so that they rotate …
