This study deals with a three-gear four-bar linkage that transforms a uniform input crank rotation into a forward-dwell motion of the output gear. Closed-form relations allowing to synthesize a geared linkage generating an approximate dwell of specified tolerance are derived. Such intermittent motions are useful in various transport and indexing devices found in textile, printing and packaging machines.
