Abstract (en)
[origin: EP0763410A2] The tool has a motor (M) above the protective casing (1), the output shaft (11) of which drives the horizontal rotor shafts (5), each of which has a rotor cage (4) in a transmission casing (15) driven by a pulley (12) on the output shaft via a two-stage reduction gear (21). The rotor cages can thus be offset in two overlaying rotation motions so that the surface being machines has no groove marks and is more even, No self-driving force acts on the tool. The rotor cages rotate in opposite directions to eliminate the "shadow" effect.
