Abstract

Aligning devices that operate by urging moving copy sheets up against solid reference edges generally require a specific amount of forward travel (a problem in some systems) of the copy sheet before alignment is completed. This problem is compounded if the copy sheet path is vertical. In this case, the copy sheet must not only be pulled upward, but also be held against gravity while a subsequent operation, e.g., punching or stapling, takes place. This article describes an aligning device that overcomes this twofold problem.
