Abstract
The drawroll unit has a heatable galette in which the shaft of the gallette is mounted in bearings which, in turn, are mounted via vibration damping devices in a stationary housing. The vibration damping devices may be in the form of bodies of interlaced wire, O-rings or the like. The vibration damping devices serve to damp vibrations of the shaft in a critical speed range within the normal speed range of the rotor so that the galette can be operated at any speed within the normal speed range.
