Abstract (en)
[origin: US4523775A] At an edge of one side of the printed sheet and which extends in the direction of a fold line there is provided a substantially triangular-shaped protruding portion. At the edge of the other side of the printed sheet, which is located opposite the fold line, there is provided an inset or retracted portion which in its size essentially corresponds to the protruding portion. At this protruding portion there can engage an opening device for opening the folded printed sheet. At the end of the processing or handling operation the protruding portion is cut away as waste. The thus cut away material portion of the protruding portion corresponds in its surface area to the material portion which is missing at the other side of the sheet at the location of the inset or retracted portion. The loss of material caused by the elimination of the protruding portion therefore is accomplished at the expense of the other side of the printed sheet.
