ABSTRACT:
A holder for the core of a yarn package includes a spindle, a conical base slidable and rotatable on the inner end portion of the spindle and an anchor in the form of a nose cone threaded on the free end portion of the spindle, the spindle being mounted on a support on the machine in which the holder is used. A plurality of flexible linkages connect the base and the anchor to turn together while permitting each to move axially independently of the other. A spring acts between the support and the base to urge the latter toward to anchor and flex the linkages resiliently outwardly against the inside of the core. The initial flexing of the linkages is adjusted to accommodate cores of different sizes by turning the anchor to move it toward or away from the base.
