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.
A method of handling sheets to be stacked in a pile against a backstop, comprising:
A method of using a stacker for arranging sheets in a pile, wherein said stacker includes a platform means to support said pile, a backstop means against which said pile is formed, said backstop being mounted on means such that said backstop is laterally movable in said stacker, and a piling assembly, said piling assembly comprising means for transporting successive sheets over said pile into jogging relationship with said backstop and depositing each said sheet onto said pile, said piling assembly means including a length-adjustable, telescoping rod means mounted in overlying relationship to said pile, said method comprising:
An apparatus for stacking sheets, said apparatus comprising:
A stacking apparatus for arranging sheets in a pile against a backstop, said apparatus including piling means for transporting successive sheets over said pile into jogging relationship with said backstop and depositing each said sheet onto said pile, said piling means including length-adjustable telescoping rod means mounted in overlying relationship to said pile and issuing pressurized air against the upper surface of each successive sheet to assist the transport and deposit of the sheet.
