Abstract: To cross-fold a moving web into one-third lengths, a cutter blade cylinder (1, 26) is at a cutting position with a counter cylinder (4, 28), which carries needles and may also carry cutting knives. The cutting knives are arranged to cut the web into a format of one-third/two-third length, respectively.
