Abstract
A thread storing and feeding device for a textile machine, which device includes a storage drum to which the thread can be tangentially fed to form a thread supply and from which it can be withdrawn particularly overend. A disc is movably supported with respect to the drum for displacing the thread supply axially along the drum. The drum has a closed circumferential wall provided with a plurality of longitudinally extending, circumferentially spaced grooves formed in the exterior surface thereof. The movable disc is positioned adjacent the upper end of the drum and has an edge section which overlaps the upper edge of the drum. This edge section has a plurality of webs thereon which project inwardly into the longitudinal grooves of the drum. The webs define a lower thread engaging surface which engages the threads so as to push the thread storage axially along the drum.
