ABSTRACT:
The present invention provides an improved apparatus for forming a fibrous web, and includes a fibrous supply mechanism for providing fibers of web material. The fibers are deposited onto a foraminous web forming layer which may optionally have a pocket recess formed therein. A foraminous spacing mechanism supports the web forming layer while allowing a substantially unrestricted gas flow from a region immediately adjacent to and downstream from the web forming layer. A gas flow regulating layer has a selected pattern of apertures therethrough, and is fixedly positioned in adjacent facing relation with the foraminous spacing means. The regulating layer provides a selected pattern of gas flow through the web forming layer. The regulating layer, the foraminous spacing mechanism and the gas flow regulating layer are constructed to form an installable and replaceable assembly, and a flow forcing mechanism provides a flow of gas through the web forming layer.
