contact with the work-rubbing wheel and heated by a gas flame, but the invention is, of course, not limited to these details. In practice we find that it is usually desirable to arrange the heated roll so that it shall run constantly in engagement with the work-rubbing wheel while said wheel is being used, in order to heat and shape the rim of the wheel, and we find that for most classes of work it is preferable to deliver the wax only occasionally to the heated roll or to the work-rubbing wheel, because very little wax is required. One of the features of this invention, therefore, consists in providing means by which the heated roll, which transfers the wax to the work-rubbing wheel, and which, by engaging said wheel, shapes the rim thereof, may run in engagement with said wheel constantly until positively thrown out of engagement, and in providing wax-supplying means which may be operated independently of the heated roll to deliver wax from time to time while the heated roll is in engagement with the work-rubbing wheel.
