Abstract
An apparatus for controlling airflow in a fiber extrusion process includes a fiber flow region between an inlet through which extruded fibers are received and an outlet through which the extruded fibers are discharged and at least one surface providing a boundary between the fiber flow region and another region, wherein the surface includes apertures permitting air to flow between the fiber flow region and the other region to control airflow at the outlet of the fiber flow region. The apparatus can include a housing which contains at least one chamber, with the surface forming a boundary between the fiber flow region and the chamber, such that the apertures permit air to flow between the fiber flow region and at the chamber. In a spunbond process, the airflow control device receives drawn filaments exiting an aspirator and deposits the filaments onto a web-forming surface with reduced air disturbance.
