Method of and apparatus for regulating the operation of a driving system for a packing machine

摘要

The operation of a driving system for a cigarette packing machine, wherein the driving system has a rotary main drive and several slave drives electrically connected to the main drive, is controlled in such a way that any selected slave drive can be disconnected from, decelerated to zero speed, accelerated from zero speed to normal speed and reconnected into the drive system in predetermined angular positions of the main drive. Each slave drive transmits motion to one or more movable parts or units of the packing machine in such a way that the movable parts do not clash even though they are movable and do move relative to each other.
