摘要 |
The invention relates to a method and to apparatus for perforating a web of material (12) intended to form an outer casing sheet of absorbent articles. As the web (12) is advanced the web is first provided with a large number of mutually separated cuts in the nip defined between raised plateaus (24) on a matrix cylinder (14) and circumferentially extending knife-edges (26) of a cutting cylinder (16). The web (12) is then deformed transversely to its plane at parts which border on each cut. The invention also relates to a perforated outer casing sheet which includes recesses in the form of mutually adjacent elongated channel-like grooves. <IMAGE> |
