A movable support, such as a cart or dolly moves along a continuous production line path, preferably in a closed loop. Each cart carries a pair of spaced essentially parallel plates, between which the structure to be heated dielectrically is to be placed. The plates are connected to a non-contacting electric RF energy coupler, such as a pair of spaced coils, between which another coil is movable, the other coil being connected over a movable arm to an RF generator. As the carts move along the path, the arm carrying the coil connected to the generator is engaged by a cart. Its coil matches with the coils carried by the cart, and is moved synchronously therewith for a predetermined period of time during which energy is transferred from the generator to the plates. To provide for uniform voltage distribution on the plates, tuning stubs or lines, preferably with a movable short circuit, are connected to the plates at suitable locations.
