Abstract

619,421. Dielectric heating. BRITISH THOMSON-HOUSTON CO., Ltd., and KEITLEY, R. Dec. 9, 1946, No. 36334. [Class 39 (iii)] Thermo plastic material 1 is passed under a wave guide 3 supplied with R.F. energy where it is superficially heated before passing under an embossing roller 4. The base plate 2 is maintained at a lower temperature to keep the body of the material cool, the local surface heating partially penetrating into the material by conduction. The outer surface of the material is cooled slightly between the point of heating at the wave guide slit 5 and the embossing roller 4 thus strengthening the outer skin of the material.
