ABSTRACT:
Apparatus for and method of pneumatically traversing a linear fibrous element during its packaging in a rotated perforated canister as air is withdrawn from the canister through its sidewalls and bottom wall; the air moves downwardly through the package during package formation to prevent freedom of movement to the element in the package and air moves generally horizontally as it is withdrawn uniformly from all sides of the canister through its perforated sidewalls to reduce air turbulence in the canister to promote ordered collection of the fibrous element.
