Abstract
A thread-storage and delivery device having a rotation shaft and a drum coaxial with and rotatably supported thereon. A feed mechanism rotates with the shaft for tangentially winding a thread onto the periphery of the drum. An advancing member is positively coupled to the drum for advancing thread windings thereon axially toward the withdrawal rim. The advancing member is rotatably supported on the shaft about an axis which is inclined at a small angle relative to the shaft axis so that the advancing member executes an axial wobbling movement as the shaft rotates. The advancing member has an outer portion projecting beyond the periphery of the drum for engaging the thread windings. Coacting braking and counterbraking elements cooperate directly between a stationary annular flange and the outer portion of the advancing member for maintaining the drum stationary. The braking and counterbraking elements are disposed in meshing engagement during rotation of the feed mechanism at only a single point which is offset circumferentially of the drum relative to the discharge end of the feed mechanism, which point rotatably migrates around the drum in correspondence with rotation of the feed mechanism.
