Abstract
Abstract Apparatus is provided for diverting groups of sheets to one or more processing machines which are adjacent to an elongated path defined by a transporting system consisting of a series of conveyors separated from each other by pivotable switches. Each processing machine can receive sheets from the transporting system in response to pivoting of the adjacent switch to a sheet-diverting position, and the switch which precedes such switch is pivotable to a position in which it diverts sheets onto an auxiliary conveyor which can be started to deliver sheets directly to the respective processing machine. The discharge end of the transporting system delivers surplus sheets to a stacker, and a switch which is located ahead of the foremost auxiliary conveyor can be caused to divert sheets into a row forming machine.
