Abstract: In a method for producing folded printed products a paper web is printed by at least one digital printing machine and the paper web is then processed by a sequence of processing steps, wherein full size sheets or web sections having at least four printed pages for a printed product with a multiple of four printed pages are cut from the paper web. The full size sheets or web sections are then folded to a folded state, respectively. The full size sheets or web sections are collected in the folded state and subsequently stitched. A buffer is formed of the full size sheets or the web sections during the sequence of the processing steps and the full size sheets or the web sections coming from the buffer are individualized to decouple the digital printing machine from at least some of the processing steps.
