Abstract
An apparatus for forming a zoned distribution of particulate material within a fibrous web includes a conveying mechanism for providing a gas entrained supply of the particulate material and a segregating mechanism for centrifugally directing at least a portion of the particulate material into an accumulation region of the apparatus. A transferring mechanism selectively directs particulate material from the accumulation region into a delivery gas stream to provide an intermittent flow volume of a selected quantity of particulate material from the accumulation region through a delivery conduit and 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 intermittent flow of particulate material from the delivery conduit into the 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 which includes zoned regions having selected, different amounts of the particulate material therein.
