A thread storage and delivery device comprises a storage drum journalled by bearings on a driven axle. A retaining sleeve is journalled in eccentric inclined bearings at a stationary support of the device and the storage drum respectively. The sleeve is drivingly engaged by a radial arm extending from and fixed to the axle. The driven radial arm winds on the thread coming from a thread supply cone onto the surface of the storage drum. Rotation of the storage drum is prevented by the inclined, eccentric journalling of the sleeve between the stationary support of the device and the storage drum. The sliding movement between the driven radial arm and the sleeve is minimized by the fact that the axis of the sleeve intersect the center axis of the device at a point which is located approximately in a region delineated by notional planes drawn radially to the center axis through the points of driving contact between the radial arm and the sleeve during a complete revolution of the driven axle.
