A flywheel continuously rotates, A piston within the rotating flywheel presses on a support which in turn presses on a friction clutch to engage the spindle press, whcih causes it to rotate with the flywheel. Upon disengagement, piston pressure is released, the spindle press lags and a part of the support lags with the spindle press, quickly disconnecting pressure on the friction clutch. Thus, the driving connection of the flywheel and spindle press is immediately disengaged from the flywheel without dealy otherwise caused by the slowness of return movement of the piston.
