  • Patent number: 6702926
    Abstract: A wire section for forming a multi-ply fiber web. The wire section includes a first belt which advances a first fiber ply toward a couch roll defining a combining section. A twin-wire zone of the wire section includes first and second wires between which a second fiber ply is initially formed in a gap former. The second wire separates from the first wire and then the first wire supporting the second fiber ply meets the first belt supporting the first fiber ply at the couch roll of the combining section to form the multi-ply fiber web. The twin-wire part is arranged upstream of the combining section along the running direction of the first belt. The second fiber ply runs on the first wire into the combining section at an angle less than 90° with respect to the belt entering the combining section. The path of the wires from the forming roll to the combining section is disclosed. A suction box or arrangement holds the second fiber ply to the first wire when the first and second wires separate.

  • Patent number: 6375799
    Abstract: Process and apparatus for producing a fibrous material web from a fibrous material suspension. The process includes conveying the fibrous material suspension between two endless, continuously revolving porous belts positioned to form a twin wire zone, removing a part of the suspension fluid through the porous belts so that the fibrous material web begins forming between the belts, guiding the two endless belts and the material web being formed therebetween through uniform pressure drainage elements, and removing additional suspension fluid with the uniform pressure drainage elements. The process further includes supplying an additive though at least one of the belts to the forming fibrous material web in a vicinity of the uniform pressure drainage, and one of controlling and regulating the supply of the additive to provide a particular ratio between quality levels of a top side of the forming web and a web underside of the forming web.

  • Patent number: 5358790
    Abstract: The invention relates to a method of reducing the water vapor permeability of a sheet of paper, which comprises the step of coating the paper sheet with a film of 5-30 g/sq.m. of a coating medium consisting of a rosin sizing dispersion containing additives improving the film-forming properties of the coating medium, which additives include surfactants and waxes. It also deals with a paper so produced.
