Abstract
Apparatus for building a rotationally symmetrically evened bobbin package with a bobbin chuck for supporting the bobbin and with a friction drive drum for driving the bobbin. The bobbin chuck is rotatable at speeds above the critical rotational speed and there is provided on the bobbin chuck a balancing element with a mass which is freely movable along a circular path concentric with the bobbin chuck axis, which mass in the centered position of the bobbin chuck is distributable evenly and automatically along the path.
