Abstract:
A godet roll for guiding, heating and conveying yarn, the godet roll comprising a projecting support, a drivable hollow-cylinclrical godet roll casing forming a circumferential yarn guiding surface, at least one radially acting bearing rotatably seating the godet roll casing on the projecting support in at least one bearing plane, the radially acting bearing comprising a plurality of bearing pole windings and a heating device comprising a plurality of heating pole windings on the support, the bearing pole windings and the heating pole windings being arranged within an annular chamber between the support and the godet roll casing, at least one of the heating pole windings being arranged in the bearing plane between the bearing pole windings of the bearing plane;wherein one or both of the heating pole windings and the bearing pole windings are arranged on the support at angular offsets from bearing plane to bearing plane; and wherein one or both of the heating pole windings and the bearing pole windings are in a spiral-shaped arrangement in the longitudinal direction of the support.
