  • Activity induction in papermaking
    Patent number: 5681430
    Abstract: The apparatus of the present invention is a papermaking machine with a forming fabric in a looped configuration. The forming fabric carries paper stock through the papermaking process. The forming fabric passes over a liquid-filled cavity which is bounded on its lower surface by a flexible non-permeable membrane. A roll with regular protrusions underneath the membrane is rotated to vertically excite the membrane, the liquid-filled cavity, and, subsequently, the paper stock in order to disperse the paper stock into a random orientation.
