Patent ID: 8157102

Claim:
A method for processing sheet material, comprising the following steps: singling the sheet material and forming a sheet stream, transporting the sheet stream comprising singled sheet material along a sheet transport path through a checking device to a plurality of output units, the sheet transport path having a first portion and a second portion downstream from the first portion, checking the sheet stream with the checking device, classifying the singled sheet material of the sheet stream as valid sheet material and/or invalid sheet material on the basis of the check, and transporting the sheet material of the sheet stream from the sheet transport path into the output units in dependence on the check, wherein the result of the check of the valid sheet material is retained, if an operating disturbance is present and/or assumed, and the valid sheet material is sorted without a new validity check and transported from the sheet transport path into the output units after elimination of the disturbance, and wherein after the elimination of disturbance the valid sheet material is removed from the second portion of the sheet transport path and inserted into an input unit for further processing without a new validity check.
