ABSTRACT:
Dry, odor absorbent and adsorbent particulate is injected into an air pervious mat of randomly overlaid fibers by a first stream of pressurized air, and is distributed among the fibers for bonding thereto by a second stream of pressurized air. Particulate which fails to bond to the fibers is withdrawn and collected, preferably from both sides of the mat. Distribution of the odor absorbent particulate among the mat fibers is controlled by controlling air stream directions, volumes and pressures and by reflecting back into the mat a selected portion of the pressurized air which has traveled through the mat.
