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. The needles (5, 6) on the cylinder transfer the one-third cut element to a second needling cylinder (9, 32) which re-transfers the cut elements to a group of needles (6) on the first needling cylinder (4, 28) so that the one-third length portion is superimposed on the two-third length portion. These two superimposed portions are then transferred to a combination needling-folding blade cylinder (10, 33) which folds the two-third portion in half and transfers the fold to a folding jaw cylinder (14, 38) so that the one-third portion is interlaced into the two-thirds portion. The arrangement has the advantage that the punctures from the puncturing needles are at the outer margin, which can be small, and be trimmed off.
