Abstract
In handling flat sheets as for example from a sheet processing machine to a downstacker a plurality of narrow parallel belt conveyors are necessarily employed. Non-uniformity in manufacture of the belts and different slippage on the pulleys causes unequal speed of travel of the individual belts resulting in improper and unequal handling. Utilizing a lower set of conveyor driving belts on which are super-imposed overlapping driven carrier belts overcomes this problem by producing uniform speed of travel of the belts.
