Abstract
A process for foam forming webs is described herein. A foamed suspension of fibers is fed into a mixing chamber and then directed through a narrow constriction where the velocity of the foamed suspension of fibers is increased. From the narrow constriction, the foamed suspension of fibers enters a forming chamber which causes the foamed suspension of fibers to rapidly decrease in velocity. In one embodiment, for example, the foamed suspension of fibers undergoes a hydraulic jump resulting in significant fiber reorientation. Through the process, fiber orientation can be controlled. For example, webs can be produced that have comparable fiber orientation in the machine direction in comparison to the cross-machine direction.
