Abstract: The invention relates to an apparatus used in the formation of paper. More specifically the present invention is directed to an apparatus for maintaining the hydrodynamic processes involved in the formation of a fiber mat or paper sheet. The performance of this apparatus is not affected by the velocity of the paper machine, the basis weight of the paper sheet and or the thickness of the mat being formed.

Abstract: The present invention refers to an under felt inclined flat former for making multilayer or monolayer sheets of paper comprising a plurality of forming units arranged along a production line. Each of the forming units is supported on corresponding rigid supports and is provided with a rolls system on which the forming unit rests when the support are removed, in such a manner that the selected forming unit can be removed from the production line for cleaning or maintenance purposes, without interrupting the operation of the former equipment.

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.
