Apparatus and method for depositing particulate material in a composite substrate

摘要

A first forming chamber and a supplying mechanism provides a flow of a selected fibrous material into the first forming chamber. A second forming chamber is selectively located within the first forming chamber to selectively divide the flow of fibrous material. A conveying mechanism transports a particulate material into the second forming chamber. A depositing mechanism dispense the particulate material. A foraminous forming layer is movably disposed within the first forming chamber and receives the fibrous material and the particulate material. A the foraminous forming layer moves, a first fibrous layer is formed on the foraminous forming layer, the particulate material is selectively deposited on the first fibrous layer, and a second fibrous layer is formed on the particulate material thereby providing the discrete layer of particulate material within the composite fibrous web.
