Abstract
An induction heating apparatus has a coil or coils which can be opened without using electrical contacts. One continuous electric current passageway is formed by a first coil section, a second coil section, a first connecting conductor and a second connecting conductor. By feeding electric power to this electric current passageway and passing an object through a space at the central portion of the coil sections, the object is induction heated. A gap is provided between the first connecting conductor and the second connecting conductor, or the respective connecting conductors can be opened and closed relative to one another to vary the size of the space therebetween. The object to be heated is carried into the space at the central portion of the coil and is carried out therefrom through the gap or the space between the conductors.
