Abstract
THE USE of direct drives for large draw presses in industry was originally brought about by the continued demand for higher rates of production as well as higher capacities in the presses themselves. The usual method of allowing the main drive motor to run continuously while the press is started and stopped by the operator controlling a clutch has become extremely costly because of production interruptions for clutch maintenance.
