Abstract
An apparatus for moving a sheet bi-directionally. The apparatus includes a first roller and a second roller. A drive system is associated with the rollers to drive the first roller in a first direction. The drive system is adapted to rotate the second roller simultaneously with the first roller in the same direction as the first roller or in the opposite direction thereto. In addition, the drive system is capable of idling the second roller so as to adjust the timing of the sheet as it moves to subsequent processing stations within a printing machine.
