Abstract

Wave guide unit suitable for heating dielectric material of any desired profile. A hort circuit plate allows energy to be reflected and redissipated as heat in the guide. For simultaneous heating, size calibration and, if apporpriate, hardening of rods, profiles or tubes of plastics materials of unlimited length.
