Abstract
An aeromechanical individualizer for individualizing entities within a fiber sample includes a cylindrical rotating beater wheel, having a non-permeable cylindrical surface and having carding elements, such as pins or wire points, on the cylindrical surface. A cylindrical feed roller and feed plate supply the fiber sample to the beater wheel in the form of a beard at a first point along the rotational path thereof. A nozzle directs a gas flow across the feed plate and the beard such that fibers are dragged from the feed plate into engagement with the carding element. At a second point along the rotational path of the beater wheel there is a doffer for removing entities of the beater wheel. An enclosure surrounds the beater wheel and substantially prevents the ingress or egress of the gas except gas flow which enters via the nozzle at the first point and which exits at the second point.
