Abstract
A dielectric heating arrangement for drying wide wet webs of material is provided in which a rotatable drum structure is provided for supporting the web on its periphery and moving it past a stationary set of dielectric heating electrodes of the stray field type positioned close to the periphery of said drum over a substantial portion of the circumference thereof. The drum periphery comprises a series of closely spaced members which extend parallel to the axis of the drum, the outer edges of said members acting as the outer periphery of said drum on which the web is supported as it is moved past said electrodes.
