Abstract: An inductively heated godet is mounted on a supporting frame which carries a rotatable drive shaft. A stationary primary winding is mounted about a magnetic core carried by a body which is fastened to the frame. A rotatable hollow shell which concentrically surrounds the primary winding is removably secured to the rotatable drive shaft.The magnetic core and rotatable hollow shell have in their longitudinal section essentially opposing L-shaped profiles with the flank portions thereof being concentric to the godet turning axis and the foot portion of each L-shaped profile extending substantially radially with respect to the godet turning axis toward the opposing flank portion of the other L-shaped profile such that the flank and foot portions of the shell and magnetic core form radially spaced annular gaps therebetween which are concentric to the godet turning axis.
