  • Patent number: 6165116
    Abstract: A system and method for creating a discontinuity in a stack of interfolded sheets in which folding rolls cooperate to interfold staggered sheets supplied in two streams of sheets, each of which is severed from a web of material. When a desired sheet count is attained, a sheet in one of the streams of sheets is folded onto itself so as to create a discontinuity in one of the streams of sheets. The folded sheet is formed by maintaining a leading portion of the sheet in engagement with a separating one roll while maintaining a trailing portion of the sheet in engagement with another roll, with the two rolls being positioned to form a nip therebetween and rotating in opposite directions.
