Abstract (en)
[origin: US4514162A] The invention relates to an appliance for heating an electroconductive material, preferably one which hardens as a result of this heating process, this material being in the form of a continuous strand which is guided inside a channel (14). In this appliance, a high-frequency generator (23) is provided, two capacitor-plates (30) being arranged on two oppositely-located sides of the channel (14), which sides are formed by walls (10 to 13) composed of an electrically insulating material, these capacitor-plates (30) being staggered by at least their length and being connected to a non-earthed terminal of the high-frequency generator (23), while two further capacitor-plates (31, 32) are arranged on each of the two sides, adjacent to the two capacitor-plates (30), these further capacitor-plates (31, 32) being connected to the earthed terminal of the high-frequency generator (23) and extending along the channel (14) for a distance such that the strand outside the heating zone is no longer at a potential. The appliance can be used, in particular, in a belt-type continuous-moulding unit for the manufacture of blanks for building materials, starting from a raw mixture having a high dielectric coefficient.
