ABSTRACT:
An adjustable intermittent incremental advance system is provided having a rotatable shaft for driving a work take-off in a start-stop rotary incremental advance. A clutch disk and brake disk alternately permit or stop rotary motion of the shaft to provide the intermittent advance. A flywheel is attached to the rotary shaft and acts through a crank arm driven by a motor to provide rotary power to the shaft for predetermined incremental movement. First and second sensors provide timed application of the clutch and brake disks to provide accurate incremental advance and prevent accumulated error in length of advance during prescribed periods of operation of the system.
