Abstract
A continuous heating apparatus for metal caps having at least one pair of high frequency electric conductors where the conductors are separated by an interval smaller than the diameter of the bottoms of the caps to be heated. A guide panel is spaced from the conductors and is adapted to engage the open end of the metal caps when the caps are moved away from the conductors towards the guide panel due to the repulsion effect occurring between the high frequency current in the conductors and current induced in the caps. A transport device moves the metal caps relative to the conductors.
