A high speed web cutting and tuck folding machine feeds webs downstream between overlying and underlying runs of feed belts having cutting and tuck folding openings spaced along the belts. Lead segments of the webs are cut at a cutting station and are fed downstream to a tuck fold station where they are drawn through tuck fold openings, folded and stacked. The machine is readily adjusted to vary the length of the cut segments and the relative lengths of the legs of the segments when folded.
