摘要： A method for forming a substantially uniform distribution of particulate material within a fibrous web includes a conveying step for providing a gas entrained supply of the particulate material. A transferring step directs the particulate material into a delivery gas stream through a delivery conduit and delivery nozzle into a web forming chamber. A fiberizing step provides a flow of a selected fibrous material into the web forming chamber. A foraminous forming layer is disposed within the forming chamber for receiving the fibrous material and the particulate material to produce a fibrous web.

摘要： An apparatus for forming a substantially uniform distribution of particulate material within the cross direction of a fibrous web includes a conveying mechanism for providing a gas entrained supply of the particulate material. A transferring mechanism directs the particulate into a delivery gas stream to provide a flow volume of the particulate material a delivery conduit and a delivery nozzle into a web forming chamber. A fiberizing mechanism provides a flow of a selected fibrous material into the web forming chamber, and a directing mechanism controls the flow of particulate material from the delivery conduit and the delivery nozzle into the web forming chamber. A foraminous forming layer is disposed within the web forming chamber for receiving the fibrous material and the particulate material to produce a fibrous web which includes a substantially uniform distribution in the cross direction of the particulate material therein.
