  • Patent number: 6547924
    Abstract: A paper machine for manufacturing textured soft paper comprises a press section with a press nip, through which an impermeable belt and a felt run with the fibrous web between them, a drying cylinder and a transfer roll forming a nip for transfer of the web to the drying cylinder. According to the invention the belt is a texturing belt having a back layer and a web-contacting layer having depressions with surface portions situated between them to form a relief pattern in the web upon passage through the press nip, the texturing belt running from the press to the drying cylinder in order to carry the textured web to the transfer nip. The felt runs away from the texturing belt before a water film formed in the press nip on the texturing belt breaks up. A device is provided before the transfer nip to apply adhesive on the drying cylinder.

  • Patent number: 6030500
    Abstract: An arrangement for feeding stock to a headbox in a papermaking machine which comprises at least one stock header with an inlet for receiving stock into the header and a plurality of stock header outlets permitting stock to leave the header. For each stock header outlet there is a stock conduit downstream of the stock header outlet permitting stock to pass from the stock header outlet, through the conduit to the inlet of the headbox. The arrangement includes a dilution header for feeding a diluent such as water to a plurality of stock conduits. The dilution header has an inlet for receiving a diluent not the dilution header and a plurality of outlets permitting the diluent to leave the dilution header. For each dilution header outlet, there is a diluent conduit permitting the passage of a diluent from the dilution header into a stock conduit.

  • Patent number: 5578170
    Abstract: A tissue web (W), which has improved formation and improved tensile properties but no appreciable deterioration of retention and layer purity, if applicable, in comparison with tissue webs produced in conventional twin wire tissue formers, may be formed in a roll type twin wire former by draining 90-99%, preferably 98-99%, of all drainable water from the slurry while on the forming roll (1), preferably a suction forming roll, the remaining 1-10%, preferably 1-2%, of the drainable water being sufficient to have a substantial amount of the papermaking fibers free in the slurry during an initial phase of a subsequent step, and, downstream of said forming roll (1), draining said remaining 1-10%, preferably 1-2%, from the slurry while vibrating the slurry sufficiently to create a micro-turbulence causing a small scale agitation of the fibers to prevent them from forming any appreciable fibrous web (W) on the two forming fabrics (3; 4) until the water remaining in the slurry is insufficient for allowing the fibers
