Abstract :
The principal methods of applying r.f. dielectric heating are recalled, with particular reference to the use of synthetic resin glues. Jig and electrode design are discussed. Aspects of the design of suitable electronic generators are outlined in conjunction with practical systems for coupling and matching the work. Some of the commercial applications of electronic heating of wood in the furniture and wood waste utilization branches of the woodworking industry are described. Applications considered cover the seasoning of timber, the bonding of laminated structures, flat, curved and moulded plywood sections, tapeless veneer splicing, edge gluing of panel and core stock, spot gluing and assembly gluing.
