Abstract

558,064. High frequency electric heating. TYNE PLYWOOD WORKS, Ltd., and SCHIFF, G. June 23, 1942, No. 8597. [Class 39 (iii)] In the manufacture of laminated and other shaped products such as plywood, mouldings, of paper, metal or glass secured by an adhesive under pressure, with or without an impregnating substance, employing high frequency electric heating, two earthed electrodes are used, which may be the head plate and base plate of the press, or separate plates mounted in the press, or two parts of a mould, and a separate live electrode between units of the material or mouldings, e.g. midway in a pile of plywood boards. The press plates may be heated by steam, hot water or electricity. Alternatively, earthed electrodes insulated from the press plates, may be used, and more than two may be employed.
