Title
(EN) Induction heating draw roller with vibration damping
Abstract
(EN)

In order to prevent transmitting vibrations which are generated by the turning of a godet to an inductor used for heating the godet, the inductor may be arranged vibration-free on bearings by a vibration damper. The vibration damper may be arranged between a carrying cylinder flange of a carrying cylinder, which accommodates the inductor, and a housing end wall. A further vibration damper ring may be provided between a centering ring, for the radial damping of the inductor, with the carrying cylinder flange being pressed against the vibration damper by screws and a pressure spring being provided between the screw and the carrying cylinder flange for pressing against the carrying cylinder flange.
