    Abstract: A clothing for supporting a wet paper web for dewatering is provided, comprising a dewatering fabric extending in a machine direction and formed only from a woven material to have a single, substantially consistent, permeability. A pair of laterally-spaced strip portions extend along the dewatering fabric in the machine direction, with each being substantially and consistently impermeable to air and forming a substantially and consistently smooth non-water-retaining surface. The strip portions define a permeable web-carrying portion of the dewatering fabric therebetween, wherein the paper web carried thereby extends over the entire width thereof. The permeable web-carrying portion allows air to flow therethrough, exclusively of the impermeable strip portions, such that the wet paper web carried only by the permeable web-carrying portion is dewatered. The width of the permeable web-carrying portion thereby defines the width of the wet paper web dried thereon. Associated systems and methods are also provided.

    Abstract: Processes for making fluff pulp sheets mechanically eliminate many unwanted fiber-to-fiber bonding (fiber bundles) in the sheet. Pulp slurry is deposited on a moving bottom forming wire to form a stock web. Pulp slurry is brought into contact with a moving top forming wire. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding. The stock web can be subjected to strong pulsating shear forces as it is being advanced along the bottom forming wire to break fiber bundles. The pulp slurry can be deposited on the bottom forming wire utilizing a headbox with dilution control to selectively adjust the concentration of the pulp slurry. Shoe presses can be used to dewater the web after it is subjected to the pulsating shear forces.

Each cartridge is connected to a steam distribution apparatus and includes a number of profiling zones that are covered by a contoured, smooth profiling screen from which steam is applied. The profiling screens are welded to baffles which enhances the structural integrity of the cartridge. No external clamps or other devices are employed that would otherwise disrupt the smooth, curved exterior surface of the profiling screens. The spaced-apart baffles also eliminate the spilling over of steam from one profiling zone to the next which has the effect of minimizing the response width for steam profiling control. The use of the drop-out cartridges permits quick and easy removal of the profiling screens for change-out or cleaning.

  • Patent number: 7820011
    Abstract: A moistening nozzle of a paper web comprises a frame (1) into which air and water are conducted. Inside the frame (1) there is arranged a water nozzle (2) wherewith water is conducted to an outlet of the moistening nozzle and an air nozzle wherewith air is correspondingly conducted to the outlet. The air nozzle (3) and the water nozzle (2) are arranged one within the other such that the air and the water form water mist that is blown out from the moistening nozzle. The air nozzle (3) is provided with an inner thread (10) that brings the air in swirling motion.

  • Patent number: 7803248
    Abstract: The invention includes a method and system for generating electricity using a drive for the electrical generator that is powered by an engine that uses high pressure hot gases produced by combustion of a fuel and an oxygen bearing gas, using at least a portion of the electricity generated to power manufacturing plant equipment and using the waste hot exhaust gases from the heat engine, such as a gas turbine, with or without a heat exchanger, in an oven in which the mat is carried through continuously on a belt, drum or with other conventional means to dry the wet fibrous mats. Optionally the fibrous mats can contain a binder and the hot waste gases can be optionally used to cure a binder.

  • Publication number: 20100206505
    Abstract: A machine and process for production of wet formed fibrous webs, in which the web is formed from a suspension on a fabric and subjected to a final drying process such as a Yankee dryer roll, while further subjecting the Web to an intermediate drying on a high-heat-transfer roll, with or without hood, before the final drying process. The intermediate dryer roll has a solid, gas-impermeable surface, and a localized heat source directly heats the dryer to a higher temperature than in the final drying process.
