Abstract
The mounting unit for the bobbin sleeve, held in a press fit on a spindle for yarn winding, shrouds three segments held by a spring unit so that as the bobbin sleeve is positioned, the radical pressure on one segment is taken up and distributed to the other two for the bobbin sleeve to be centered over the spindle. The purpose is to give an automatic centering function, giving high-speed and friction-free rotation.
