Abstract
A package holder for use in winding yarn packages comprises at least one arm adapted to support a bobbin tube and pivotable about a first axis as a yarn package is formed on the tube. The arm is also pivotable about a second axis extending transversely to the first axis to make it possible to install or remove the bobbin tubes or packages. A first member is provided which is movable with the arm during the pivoting movement thereof about the first axis. A second member is engaged by the first member and is so mounted that relative movement of the first and second members occurs during the pivoting movement of the arm about the first axis. The zone of contact between the first and second members either includes or passes so close to the second axis that the forces acting between the first and second members have no or only negligible effect on the pivoting about the second axis, or a biassing arrangement for pivoting the arm about the second axis compensates for the effect of any offset of the zone of contact relative to the second axis on such pivoting about the second axis.
