Abstract
A bobbin holder shaft is journalled in a bobbin holder shaft support that is, in turn elastically supported relative to a fixed frame. When the support weighs more than the shaft plus the full amount of yarn to be wound thereon, and the lowest order resonant speed is below the operating speed, a high operating speed can be achieved without inducing a resonant vibration even though a pronounced band or ribbon appeared on the wound yarn ball. In a preferred embodiment, the elastic support is provided by axially spaced O-rings and an oil-filled reservoir defined axially between them.
