Abstract
A godet roll for guiding, heating and conveying yarn on the circumference of a hollow-cylindrical godet roll casing. The godet roll casing is seated on a projecting support by at least one magnetic bearing having bearing pole windings, and a heating device with heating pole windings is arranged on the support. Some bearing pole windings and at least one heating pole winding are arranged together in one bearing plane, so that the bearing areas can be heated. Sensors provided for detecting the position of the godet roll casing are arranged outside of an annular chamber formed between the godet roll casing and the support in order to prevent a thermal overload of the sensors.
