  • Patent number: 8206555
    Abstract: A papermaking machine for making paper includes a forming section, a press section, and a drying section. The paper web is pressed between two press members while enclosed between a press felt and a transfer belt having non-uniformly distributed microscopic depressions in its surface, the web following the transfer belt from the press to a transfer point at which the web is transferred via a suction transfer device onto a structuring fabric, the web then being dried on a drying cylinder. The transfer point is spaced a distance D from the press nip selected based on machine speed, a basis weight of the web, and the surface characteristics of the transfer belt, such that within the distance D a thin water film between the web and the transfer belt at least partially dissipates to allow the web to be separated from the transfer belt.

  • Publication number: 20120103550
    Abstract: An apparatus for transferring a wet paper web from a press nip to a drying cylinder of a papermaking machine, and for structuring the web, includes an impermeable transfer belt that passes through the press nip along with the paper web, and a permeable structuring fabric for transfer of the web onto the drying cylinder, the structuring fabric being arranged in a loop within which a suction transfer device is disposed. A web-contacting surface of the belt has a non-uniform distribution of microscopic-scale depressions, and a suction zone of the transfer device includes a transfer point spaced a distance D from the press nip. The belt is arranged to bring the web into contact with the structuring fabric in the suction zone for a length L, such that suction is exerted on the paper web to transfer the paper web from the belt onto the structuring fabric at the transfer point.

  • Patent number: 8075738
    Abstract: An apparatus for transferring a wet paper web from a press nip to a drying cylinder (52) of a papermaking machine, and for structuring the web, comprises an impermeable transfer belt (35) having a web-contacting surface, the wet paper web passing through the press nip enclosed between a press felt (33) and the transfer belt, and a permeable structuring fabric (37) for transfer of the web onto the drying cylinder, the structuring fabric having a structured surface and being arranged in a loop within which a suction transfer device (38) is disposed, said suction transfer device having a suction zone (41).

  • Patent number: 7563344
    Abstract: Wet-pressed creped tissue sheets exhibit continuous undulating valleys separated by continuous mono-planar macro-ridges running in the machine direction of the sheet, the macro-ridges being of a lower fiber density relative to the fiber density of the undulating valleys. The tissue structure can be created by pressing a densified tissue web against the surface of a Yankee dryer while the web is supported by a texturizing (molding) fabric having a web-supporting surface having highly topographic continuous or substantially continuous ridges and valleys and thereafter creping the web.
