Abstract
Methods and systems of forming a random fiber web using pneumatic fiber feeding system are disclosed. The method can optionally comprise: providing a plurality of moveable apparatuses including a lickerin and a feeder, the lickerin configured to remove a plurality of fibers from a fibrous mat delivered to adjacent the lickerin by the feeder; doffing the plurality of fibers from the lickerin at a doffing location within the system; communicating an air supply to entrain the plurality of fibers with the air supply after the doffing; and collecting the plurality of fibers from the air supply to form the random fiber web.
