Abstract
An aspirator provides linear control over air flow for manipulation of extruded fibers. A distribution manifold has a barrel valve between first and second flow channels, enabling precise, linear control over air flowing from a charge conduit to a pressure chamber surrounding a discharge pipe. Plural orifices in the discharge pipe connect the pressure chamber to the interior thereof, which is configured as a Venturi tube. Discharge pipe surfaces that can contact filaments therein are of hardened material while non-contact surfaces are of lighter materials.
