Abstract
Improved aperturing of a web can be obtained by providing pins with an extended tapered section that is substantially convex in shape. When the tapered section is longer than the penetration depth of the pins into the receiving recesses of a female roll, frictional forces in the nip between layers are reduced. Pins with extended tapered sections can be used in devices for producing apertured composite web assemblies comprising sections of absorbent matter attached to a nonwoven web or other carrier layer.
