An apparatus for segmenting a continuous running web into a stream of discrete articles by cutting the web transversely at uniformly longitudinally spaced intervals; and which apparatus may also effect U-folding of each of the discrete articles. The apparatus is of the type which includes a flight of longitudinally spaced, web engaging friction plates which provide cutter access to the web through spaces intermediate adjacent friction plates. The apparatus further includes a constant clearance infeed nip which is formed in part by the spaced friction plates of the flight passing over a circumferential portion of an infeed roll having circumferentially spaced, radially extending lugs, and which lugs are configured and disposed to engage the web by extending through the spaces intermediate the spaced friction plates. Alternatively, the flight of friction plates may be integrated into a unitary apertured conveyor belt; and the cutter may be integrated into such a constant clearance nip.
