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.
Claims13
A godet roll for guiding, heating and conveying yarn, the godet roll comprising a projecting support extending in a longitudinal direction, a drivable hollow-cylindrical 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 radially extending bearing plane, the radially acting bearing comprising a plurality of bearing pole windings in said bearing plane, and a heating device, comprising a plurality of heating pole winding, on the support, the bearing pole windings and the beating pole windings being arranged within an annular chamber between the support and the godet roll casing, whereby at least one of the heating pole windings is arranged in said radially extending bearing plane between at least two bearing pole windings in the same radially extending bearing plane.
