Abstract
A lever connected to the working-station drive shaft of a packaging machine is accelerated by an energy source, for example, a piston-and-cylinder arrangement to rotate this shaft in the same sense as a continuously driven main drive shaft and enable a single-tooth jaw clutch to couple the two shafts without shock or impact.
