Two reduction gears (19, 20) which can be separately driven are provided in the casing (12) and are arranged coaxially to the first axis, the reduction gears being arranged to drive coaxial bevel gears (24, 25)which, in their turn, are engaged with additional bevel gears (28, 29) supported by the casing (12) and extended at a right angle to the previous bevel gears (24, 25), the shaft of one of the bevel gears (28, 29) supporting a flange (31) which rotates around a second rotary axis (30) running at a right angle to the first axis (11). | |
