PROBLEM TO BE SOLVED: To make it possible to automatically regulate the output of a high-frequency generator in response to the quantity of works to be heated by providing an output altering stage for altering the output of the generator in response to the quantity of the works in a high-frequency heating tank. SOLUTION: When a work is moved and the pulse from a work moving amount detector 3 is counted by one by a work length calculating means 31 in a tank, the divided voltage output by generation controller 21a is raised stepwise at one level by output altering means 32. As the level is raised, the high-frequency outputs of magnetrons 20a, 20b to a high-frequency vulcanizing tank is raised by about 0.67kW. Thus, since the high frequency to meet the work length in the vulcanizing tank is output, the work is suitably heated and not overcured. |
