ABSTRACT:
An apparatus for applying particulate powder material to a moving fibrous substrate is disclosed. The apparatus includes a volumetric dry material feeder for forming a continuous stream of particulate powder material. The continuous stream is then transmitted through a nozzle and exits at an outlet thereof. The nozzle is movable between a first and second position 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 is disposed beyond the outlet of the nozzle and intermediate of the first and second positions. In operation, the motion input drives the nozzle to oscillate between the first and second positions at a variable speed over each product cycle. As the nozzle crosses a plane of the flow separator, the continuous stream of particulate powder material exiting the nozzle 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 to form a layer of particulate powder material within a predetermined portion of the substrate. The second intermittent stream is recirculated back to the volumetric dry material feeder.
