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.
