Abstract (en)
[origin: US4850400A] The weft yarn store comprises a rotating winder and a stationary drum adapted to receive a yarn winding. A drive in the form of a motor or magnets is disposed at least to some extent inside the drum to activate an adjusting sleeve to move the stirrups of the drum. The power required for the drive is transmitted without contact. Consequently, the effective diameter of the store drum can be adjusted while the store is in operation and automatically.
