ABSTRACT:
A sheet handling device for receiving either a flow of sheets or a flow of transverse rows of interconnected carton blanks from a discharge end of a processing apparatus and delivering the sheets or rows into the input end of a second processing apparatus characterized by a first conveyor path of belts extending between the input and exit ends of the device, a second conveyor path or belt having a longer or greater length than the first path extending from the input end to the exit end, nip rollers for forcing the belts of each path into engagement with each of the sheets in the first and second path to impart a new speed thereto, the ends of the first and second paths being arranged so that the sheets in the second path will be deposited on a following sheet traveling in the first path and a pivotable blade arranged adjacent the input ends of each of the paths for alternately directing the sheets into the paths. In order to be able to handle the transverse rows of inteconnected cartons which have substantially no spacing between adjacent rows as they are discharged from the processing apparatus, the input end includes rollers which can be driven at an accelerated speed to accelerate the passage of the rows to obtain a spacing between the rows to enable the pivotable blade to be actuated and each of the paths is provided with a control device for immediately decelerating the row after it is directed into one of the paths and prior to being received by the nip rollers.
