| 20120073777 | Methods Employing an Impermeable Transfer Belt in a Papermaking Machine - 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. | 03-29-2012 |

| 20090173465 | Support Body For An Apparatus Having An Extended Nip For The Treatment Of A Fibre Web - A support body for an apparatus having an extended nip formed between the support body and a counter-pressure member, having a working surface, being elastically deformable, and comprising a plurality of pressure chambers pressurized for controlled expanding in the direction of the working surface in order to load the nip. According to the invention the support body comprises a plurality of reinforcing profiles disposed in at least one chamber of the pressure chambers, the interiors of the profiles being in fluid communication with one another via holes, a wall of the profile facing said working surface including holes for communicating fluid between the interior of the profile and the chamber in which said profile is located, said profiles providing an inner support to walls defining said at least one chamber. | 07-09-2009 |
