Abstract:
Apparatus for continuously cutting side-by-side rectangular perforated areas in a web of paper or nonwoven material. The apparatus includes spaced machine direction perforator wheels with coacting anvil wheels, a cammed slitter to cut short slits in the machine direction in the corner areas of the eventual rectangular perforated area and a transverse perforator including flexible rotating knives and a stationary anvil blade for cutting transverse perforations which outline the side-by-side rectangular perforated areas. The apparatus is preferably used for cutting perforated areas in a web which will later be converted into individual diaper topsheets, each of which has a perforated removable area. The perforations are in the form of short cuts, but the corners are preferably formed with elongated slits in order to facilitate removal and separation in the ultimate product.
