ABSTRACT:
A method and device for depositing fibers on a forming wire. In one embodiment, a device includes a fiber reservoir having an inlet, a first outlet configured to pass air or gas, and a second outlet configured to pass fiber. The device also includes a fiber meter configured to move fiber out of the reservoir to a forming head via mechanical action and along substantially the entire width of the forming head. The forming head includes one or more air inlets and one or more agitators to blend and open the fiber received from the fiber meter. The forming head interfaces with a vacuum source that draws air into the forming head through the air inlets, which can be adjusted to affect volume and velocity of air drawn into the forming head.
