ABSTRACT:
An improved, continuous airlaying apparatus for making airlaid articles such as discrete absorbent fibrous cores for catamenial napkins and disposable diapers and the like having high structural integrity, and good edge definition. The articles are airlaid in discrete cavities as they pass through a deposition zone of the apparatus, and are compacted a predetermined amount prior to their being removed from their respective deposition cavities. An exemplary mechanism for effecting the compacting comprises a lugged cylinder having circumferentially spaced lugs which are configured and pitched to mesh in a quasi gear-like manner with the deposition cavities.
