Pulleys are located on the shafts of the two rolls and a continuous garter spring is placed around the pulleys. When one sheet is in the nip, slippage occurs between the garter spring and the pulleys; when multiple sheets are in the nip, slippage occurs between the sheets and the retard roll is driven by the garter spring.
