Abstract
An improved system for controlling the operation of a cyclically moving shear mechanism, including a circuit for automatically synchronizing the cyclical actuation of a fluidic drive assembly to the timing of a related mechanism such as a glass gob feeder. The synchronizing circuit increases or decreases a 'start delay time' each cycle if a Return sensor signal precedes or follows a Start signal, respectively. A count corresponding to the Start Delay period is adjusted within a single cycle by the amount required to bring the return sensor signal and the start signal back into synchronism in subsequent cycles.
