Abstract: Apparatus for perforating Z-folding, and further processing long tissue webs to form stacks of Z-folded facial tissues or the like for being packaged in consumer boxes. In one embodiment, two webs are perforated and superimposed at the nip of counterrotating rolls so the perforations of one web are staggered between the perforations of the other web. The webs are Z-folded by vacuum adhering portions of the superimposed webs alternately to the portion of each roll below the nip, drawing the adhered portions back and forth out of the mutual tangent plane forming the nip to start Z-folds. The folds are creased by further means. A continuous stack of Z-folded tissues is formed and can be subdivided into counted stacks of tissue for packaging.
