A method and apparatus for drying or curing rigid cylindrical and flexible belt substrates includes: a curing chamber defining a central axis; a support structure selectively receivable within the curing chamber and including a support for at least one substrate along the central axis which rotates the at least one substrate about the central axis; a curing mechanism surrounding the at least one substrate within the curing chamber for expelling temperature controlled low velocity air toward the at least one substrate as the at least one substrate rotates about the central axis without axial movement relative to the curing chamber; and inductive coils surrounding at least a portion of the at least one substrate within the curing chamber for indirectly heating the at least one substrate. Preferably, the at least one substrate is dried/cured by combination of indirect RF induction heating at the same time or prior to low velocity air impingement. By varying the frequency, power, coil diameter and spacing, heatup rates and temperatures can be very closely controlled and very rapid heatup rates can be achieved.
