FIG. 2

A sheet handling system in which sheets are separated from a stack I and conveyed

while contacting only one side of the sheet. A porous vacuum transport belt 2 is lifted at one edge by means of deflector plates 3 to permit a pivoted (at 4a) sniffer

tube 4 to operate. The function of the sniffer tube 4 is to reach down to the top sheet of the stack 1 below the presently stationary, transport belt 2 and then lift upwards carrying the corner of the top sheet past corner snubbers to a sufficient height to cause the remaining width of the sheet to adhere to the belt across the

corresponding widths. Air to the sniffer tube is then cut off by a valve and the belt 2 is then driven in the direction shown, thus transporting the sheet as required for subsequent processing in the machine. The suction chambers 7 inside the belt

configuration and a porous end roller (s) 6 are coupled to a source of suction in the normal manner used in vacuum transports. The belt is made of a resilient porous material in order to allow the edge of the belt to be deflected.
