ABSTRACT:
An interfolding apparatus and method, utilize, first and second sheet-cutting-and-overlapping arrangements and an interfolding arrangement simultaneously mounted and operatively interconnected in a common frame, for alternatively selectively forming a first or a second interfolded pattern having a given folded width, without replacement of components of the interfolding apparatus. The first interfolded pattern is formed from a first stream of overlapped sheets of a first length cut from a web of sheet material fed along a first path extending through the first sheet-cutting-and-overlapping arrangement to the interfolding arrangement. The second interfolded pattern is formed from a stream of overlapped sheets of a second length cut from the web of sheet material fed along a second path extending through the second sheet-cutting-and-overlapping arrangement to the interfolding arrangement.
