Abstract

An improved means for mounting the induction coil of an inductively heated godet about the magnetic core thereof so as to eliminate any movement or play therebetween in operation caused by heat expansion and vibration. The improvement comprises placing an elastic intermediate piece between the coil and magnetic core which compensates for any unequal thermal expansion of these elements. In the preferred embodiment of the present invention, the intermediate piece is constructed of a hose-like hollow chamber through which a coolant under pressure is circulated from an external source.
