| description | An apparatus and method for applying particulate powder material to a moving fibrous substrate (58) is disclosed. The apparatus includes a volumetric dry material feeder (22) for forming a continuous stream of particulate powder material. The continuous stream is then transmitted through a nozzle (38) and exits at an outlet (42) thereof. The nozzle is movable between a first and second position (47, 49) by a motion control. The motion control includes an adjustable differential gear box and an encoder for synchronizing the dispensing of powder at a predetermined location of the substrate. A flow separator (41) is disposed beyond the outlet (42) of the nozzle (38) and intermediate of the first and second positions (47, 49). In operation, the motion input drives the nozzle (38) to oscillate between the first and second positions (47, 49) at a variable speed over each product cycle. As the nozzle (38) crosses a plane of the flow separator (41), the continuous stream of particulate powder material exiting the nozzle (38) is split into two intermittent streams of particulate powder material. The first intermittent stream is applied to a predetermined location of the moving fibrous substrate (58) to form a layer of particulate powder material within a predetermined portion of the substrate (58). The second intermittent stream is recirculated back to the volumetric dry material feeder (22). |
