A method of forming a fibrous web including the steps of providing a fiber slurry, depositing the fiber slurry between an inner forming wire and an outer forming wire, wherein the outer forming wire comprises a structured fabric and the inner forming wire contacts a segment of a forming roll, and rotating the forming roll so that the fiber slurry moves into contact with the structured fabric.

The present disclosure relates to methods and apparatuses for removing water from a wet fibrous web. During the process of making a fibrous structure, a capillary dewatering apparatus remove water from a wet porous web. In some configurations, a capillary dewatering apparatus may include a capillary porous media. A molding member, such as a papermaking belt comprising an air permeable fabric, may advance the wet fibrous web onto the capillary porous media, wherein the fibrous web is positioned between the capillary porous media and the air-permeable fabric. An energy transfer surface may be positioned in contact with the air-permeable fabric or the outer circumferential surface, wherein the energy transfer surface operates to vibrate the capillary porous media. In turn, the vibration helps to drive water through the capillary porous media, allowing additional water to flow from the fibrous web and through pores in the capillary porous media.

A device for reducing a moisture content of a moist, fiber-containing material has a double-belt press with a first endless belt and a second endless belt of metal, wherein a pressing zone for pressing liquid out of the fiber-containing material is configured between the first endless belt and the second endless belt, wherein, further, a belt of a liquid-absorbing material that is guided between the two endless belts and through the pressing zone is arranged, wherein a surface of the belt liquid-absorbing material that faces the first endless belt forms a contact surface for the fiber-containing material.

A suction roll includes: a cylindrical shell having an internal lumen and a plurality of through holes; a suction box positioned in the lumen of the shell; a suction source operatively connected with the suction box; at least one seal strip attached to the suction box and configured to assist in forming a seal between the suction box and the shell; a sensor attached to the seal strip; and a controller operatively connected with the sensor. The sensor is configured to convey signals to the controller, the signals being processed in the controller to provide data on the seal strip on at least one of temperature, wear, vibration, and pressure.

A method of forming a fibrous web on a papermaking machine including the steps of depositing a dilute fiber slurry out of a headbox to a forming area comprising a forming surface made up of a structured fabric, wherein the structured fabric is supported by a breast roll and a forming roll, and the forming area is devoid of any additional fabrics or belts other than the structured fabric, draining the dilute fiber slurry through the structured fabric, and drying the fiber slurry.
