Abstract
A thread-storage and delivery device, which includes a storage drum on which a thread is wound to form a thread storage and from which the thread is withdrawn for supply to a textile machine. The drum is formed from a plurality of elongated rods disposed in a cylindrical pattern about the drum axis. The rods define an outer peripheral surface on which the thread windings are engaged. A thread-advancing device has portions thereof projecting radially outwardly between the rods for engaging the thread windings to slide them axially along the peripheral surface. Each rod is provided with a plurality of parallel narrow grooves extending axially thereof, which grooves are separated by narrow axially extending ribs. The outer free edge of each rib defines a narrow axially elongated surface section which defines a part of the peripheral drum surface and is engaged by the thread windings.
