<p>PURPOSE:To remove foreign matter without damaging a core by scouring the surface of a core with a heating member in the shape of a round bar, and burning foreign matter such as rubber, etc., projecting from the surface of the core thereby removing it. CONSTITUTION:In the manufacture of a rotating transformer, which provides a plurality of coil grooves 2a coaxially on the surface of a core 2 made in disc shape, and installs coils 11 in the coil grooves 2a, and bonds them with rubber bond 12, this is a method of scouring the surface of the core 2 with a ceramic heater 7 as a heating member in the shape of a round bar, and removing the rubber 12a as the foreign matter projecting from the surface of the core 2. Hereby, rubber, etc., projecting above the surface of the core from inside the coil groove can be removed completely, and the drum can be rotated smoothly.</p> |
