ABSTRACT:
A method and apparatus for drying and setting the adhesive on the backs of books contained in book blocks or similar articles by vaporizing the water using high frequency RF energy. The books are generally mounted in clamps and moved on a conveyor from the input of the book binding machine through a ventilation system to its output. A high frequency RF field is disposed along the conveyor and has a plurality of spaced apart RF electrodes wherein the electrodes adjacent to the input and output are more closely spaced together than those in the center of the machine so that the energy of the high frequency RF field can be varied in an inverse proportional relationship to the dielectric loss factor of the adhesive layer during the drying cycle.
