- 2 - ABSTRACT OF THE DISCLOSURE The method relates to the feeding of continuous webs of pre-printed wrapper material to an automatic cutter, for the production of single printed wrapper sheets. The defective portions of the continuous webs, resulting for example from printing defects, are not previously removed, but are marked with an initial spot mark of any type adapted to be sensed by sensor devices and with a visible termination mark. The rolls of pre- -printed continuous web are mounted on a packaging machine which has an automatic roll shift-over and splicing device. Whenever an initial spot mark of a defective portion is sensed, the automatic shift-over device will interrupt the feeding of the defective web, and shift over to the reserve roll. In the meantime, the operator will manually remove the defective portion, the end of which is marked by the visible termination spot mark and will insert the leading end of the conti- nuous web, from which he has removed the defective portion, again into the automatic shift-over and splicing device.
