ABSTRACT:
A continuous web of paper with a series of transversely extending rows of perforations between successive panels is folded in zig-zag fashion by reducing the speed of each oddly numbered panel and simultaneously diverting the oddly numbered panel from the path of the web while the evenly numbered panels immediately following the diverted oddly numbered panels continue to advance at a higher speed so that the neighboring panels define loops while the next-following evenly numbered panels catch up with the immediately preceding oddly numbered panels. The loops are stabilized by suction-operated conveyors and by admission of compressed air thereinto, and the resulting stack of overlapping panels is severed at intervals across selected rows of perforations to form a series of smaller stacks each of which contains a desired number of panels.
