摘要：Towels or other segments of sheet material are moved along an upper pair of downwardly inclined guide plates 31, 32, and the side edge portions 16 of the segments are folded inwardly and under the central portion 20 of the segment and under the upper guide plates. The leading end portion of the segment is moved off the lower ends of the upper guide plates and onto a lower pair of guide plates 34, 35 that are coextensive with the upper guide plates, the two pairs of guide plates are then separated, and a fold blade 101 moves upwardly between the separated guide plates to form a cross fold 106 intermediate the ends of the segment. The movement of the intermediate folded portion of the segment is continued in an upwardly-inclined direction, which pulls the leading and trailing end portions together.
