    Abstract: A press apparatus is disclosed for removing water from a web that has been supported on an upstream forming wire. The press apparatus includes a first roll which cooperates with the forming wire for transferring the web from the forming wire to the first roll, the first roll being a suction roll. A second roll is disposed downstream relative to the first roll, the second roll cooperating with the first roll for defining therebetween a first nip for the removal of a first portion of the water from the web during passage of the web through the first nip. The second roll is a suction roll. A third roll is disposed downstream relative to the second roll, the third roll cooperating with the second roll for defining therebetween a second nip for the removal of a second portion of the water from the web during passage of the web through the second nip. The third roll is a plain roll. A looped first press felt extends around the first roll and through the first nip such that the first press felt supports the web from the forming wire to the first nip, the first press felt being disposed between the web and the first roll from the forming wire to the first nip. Also, a looped second press felt extends around the second roll and through the first nip such that the second press felt supports the web from the first nip to the second nip, the second press felt being disposed between the web and the second roll from the first nip to the second nip.

    Abstract: An apparatus and method for forming a fire retardant-treated fiber product is provided. A first nip is defined by a pair of juxtaposed processing members, and is configured to receive a fiber product therethrough. At least one of the processing members comprises an incisor member extending from a processing surface thereof, and interacting with and altering a surface of the fiber product directed through the first nip. A second nip is defined by a pair of juxtaposed compression members, and is configured to receive the fiber product therethrough. Compression surfaces of the compression members cooperate to compress the surface of the fiber product within an elastic range associated therewith. At least one of the first and second nip is arranged to receive a fire retarding solution such that the fiber product is interacted therewith at least upon entering the at least one of the first and second nip.

    Abstract: A paper machine having a forming fabric with a paper side plurality of weft and warp yarns interwoven to form a layer contacting a paper web. A plurality of weft and warp yarns are interwoven to form a machine side layer for the forming fabric. A plurality of warp binder yarns are interlaced with the paper side and machine side yarns to form a multiple layered forming fabric. The weft yarns in the machine side layer are greater in diameter than the warp yarns for maintaining width stability of the fabric. The fabric is characterized by high permeability, high void volume and a high Beran's Fiber Support Index.
