Abstract
A relief device for the tamping mechanism of an offset sheet set stacker. A sheet set stacker is provided having a plurality of retractable tamping mechanisms for alternately offsetting sheet sets within the stacker. Each tamping mechanism is provided with a spring biased follower arm which locks the tamping mechanism in an operative position. A relief device in the form of an oblong pivot mount allows the tamping mechanism to not only pivotally retract from an operative position but to also shift a slight amount transversely to the paper path process direction. This slight shift prevents a binding of the tamper against the just compiled sheet stack and minimizes the occurrence of sheet stack disturbance.
