A method and system for aligning a moving stack of sheets. A pair of cams, positioned on opposite sides of the moving stack, rotate synchronously to each other but in opposite directions. When the stack approaches the cams, the distance between the outer surfaces of the cams is wider to the stack width to receive the stack. As the stack moves forward further, the distance between the cam surfaces is reduced so as to allow the cam surfaces push the sheets toward a center line until the distance between the cam surfaces is substantially equal to the width of the sheets. In a sheet collator where sheets are moved by a plurality of finger pairs which are linked to a moving chain, the cam can also be linked to the moving chain so that their rotation is synchronous to motion of the stacks.
