(under subclass 207) Device wherein sheets are successively delivered onto the top of a stack of delivered sheets, and wherein a layer of ambient atmosphere is caused to form below the sheet last delivered and above the top of the stack, which layer of air permits the last delivered sheet to float down onto the top of the stack.
(1) Note. Exemplary of the manner in which the layer of air is formed are: (1) air blast nozzles located above the stack and directed upwardly, and (2) a wall confining the edges of sheets at the top of the stack and extending to also confine the edges of the sheet last delivered and the wall having perforations that permit the controlled escape of air trapped between the sheet last delivered and the top of the stack.
