Abstract
A coupling has a low-torque/high-slip clutch connected between a drive output and an input constituted by a press, shear, or stamper, and a high-torque/low-slip clutch also connected between the output and the input. In a startup phase the low-torque/high-slip clutch is engaged and the high-torque/low-slip clutch is disengaged to bring the load input up to a predetermined rotary threshold speed. Thereafter in a working phase the low-torque/high-slip clutch is disengaged and the high-torque/low-slip clutch is engaged to drive the load at a rotary speed at least equal to the rotary threshold speed.
