Abstract:
1. A device for depositing fibers on a forming wire, the device comprising: a fiber meter configured to deliver fiber to a forming head via a mechanical action that is substantially independent of an air flow and substantially along an entire width of a forming head; and a forming head positioned to receive fiber from the fiber meter, including one or more agitators and one or more air inlets, and configured to interface with a vacuum source used to draw air into the forming head through the one or more air inlets and such that a moderate negative pressure exists in the forming head where fibers are first introduced from the fiber meter, the one or more air inlets configured to affect the volume and velocity of air drawn into the forming head, wherein the forming head has a first width and the fiber meter has a second width that is substantially the same as the first width of the forming head.
