Abstract
A piling assembly for a sheet stacker utilizes air pressure to corrugate a paper sheet for stiffness and to transport the sheet from a conveyor onto a pile formed against a backstop. The assembly is comprised of a plurality of telescoping rods which overlie the sheet pile and issue air jets in a downward and lateral direction onto the upper surface of a sheet. The mechanism further includes a lift means situated beneath the sheet and directing air against the undersurface of the sheet, so that the sheet can float over the pile as the sheet is jogged against the backstop in the stacker. The backstop is made movable and the telescoping rods are adjustable to accommodate various lengths of sheet in the stacker.
