ABSTRACT:
A spring loaded core adaptor is disclosed, including a hub of circular cross section for releasable engagement with the internal surface of one end of a hollow tubular core. The engagement permits rotation of the core in a preferred direction about its longitudinal axis for winding continuous material under tension on the outer surface of the core. The hub disclosed includes one or more arched spring clips secured within grooves arranged along the external surface of the hub. The spring clips engage a portion of the internal surface of the core to prevent relative rotation between the core and the hub in response to the rotation of the hub in the preferred direction; and, to releasably engage a portion of the internal surface of the core to permit relative rotation therebetween in response to the rotation of the hub in the opposite direction.
