ABSTRACT:
An apparatus for forming a fibrous structure includes a rotatable main drum having projections on its outer periphery for separating fibers from a fibrous feed, and directing the separated fibers through a fiber working section. The working section includes a movable satellite member positioned close to the main drum and having projections on its outer periphery for cooperating with the projections on the main drum to individualize the fibers as they are directed through the working section. A baffle is positioned adjacent the satellite member; between the satellite member and the exit from the working section. The baffle includes a lower air-directing section positioned close to the outer periphery of the main drum and having an air-diverting surface for intercepting air conveyed to it by the outer periphery of the main drum as the main drum is rotated. The air-diverting surface deflects a portion of the intercepted air in a direction generally away from the outer periphery of the main drum into the region between the adjacent satellite member and the baffle to increase the static pressure in that region. The air-diverting surface also deflects a portion of the intercepted air through a constriction provided between the outer periphery of the main drum and a peripheral surface segment of the air-directing section.
The method of this invention relates to the high speed formation of a fibrous structure employing the above-described apparatus.
