A method of forming a random fiber web using pneumatic fiber feeding system is disclosed. The method includes 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. The method also includes doffing the plurality of fibers from the lickerin at a doffing location within the system. The method also includes communicating an air supply to entrain the plurality of fibers with the air supply after the doffing. The method also includes controlling the air supply within a flow path between the lickerin and a collector. The method also includes collecting the plurality of fibers from the air supply on a collector to form the random fiber web.
