  • 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: 5545294
    Abstract: A three-layer headbox has two rigid separator vanes (11; 12) mounted in the headbox slice chamber (10) to form two outer stock flow channels (39; 41) and an intermediary one (40). The upstream end of each vane (11; 12) is securely fixed in cantilever fashion and its downstream end (15; 16) is unattached and free and provided with a vane extension (17; 18). Also the downstream end (20; 22) of the extension (17; 18) is unattached and free and is located just downstream of the slice opening (14). The vane extension (17; 18) is thinner than the vane (11; 12), so that a step (23, 24) is formed on each side of the vane (11; 12) and extension (17; 18) assembly. To improve the layer formation, each vane (11; 12) and each vane extension (17; 18) has a portion located in a converging downstream portion (13) of the slice chamber (10), and the vane portions and the extension portions are of substantially equal length.
