Patent ID: 7670100

Claim:
An apparatus for aligning an entire stack of flexible sheets resting on a transport substrate, with said transport substrate, wherein an outer lower edge portion of said entire stack is projecting laterally past at least one edge of said transport substrate, the apparatus comprising: an aligning element shiftable horizontally toward and away from the one edge of the transport substrate and having a face of said aligning element directed toward the stack and including a slip-preventing layer on the face of said aligning element in a region corresponding to said outer lower edge of said stack; wherein the aligning element further comprises a pair of aligning elements wherein each said aligning element has a vertically oriented face and a horizontal surface portion adjacent the face and generally level with an upper surface of the transport substrate; wherein when the aligning element is shifted horizontally toward the stack and substrate edge, said slip preventing layer engages and supports the projecting outer lower edge portion of the stack and pushes the entire stack inward on the transport substrate thereby altering the alignment of said entire stack with respect to said transport substrate without downwardly bending or deflecting the flexible sheets that form said outer lower edge of said entire stack.
