摘要

The machine has a transmission unit comprising a pulley integrated with an output shaft (2), and a reverse pulley (14) rotating freely around an axle. An arrangement with two pulleys (16, 17) is mounted freely rotatable around an axle (18). The pulley (17) is connected by a belt (20) to a pulley (5) for driving a transmission shaft in a direction opposite to the output shaft.
