ABSTRACT:
The mechanism comprises at least one driving pulley comprising of two parts which are each provided with one part of a cable groove, which groove has a relatively great output transmission capacity. The parts are pressed toward each other by pressing devices, which comprise spiral springs or leaf springs which rest on and are coupled for rotation with the driving pulley parts. Each driving pulley may cooperate with another (identical or conventional) driving pulley which rotates at the same speed, e.g., by means of two gears mounted on the peripheral edges of the driving pulleys.
