摘要： An apparatus and method is disclosed for removing fluid from a fibrous web. The apparatus includes a press member and a blanket which cooperates with the press member for defining therebetween an elongate pressing section such that the web is pressed between the press member and the blanket during passage through the pressing section. An elongate shoe urges the blanket towards the press member such that when the web passes through the pressing section, fluid is removed from the web. A heater is disposed adjacent to the press member for transferring heat to the web such that when the web passes through the press section, the web is subjected for an extended period to increased pressure and temperature so that water vapor generated within the pressing section during passage through the pressing section forces the fluid in the liquid phase away from the web. The press member defines a pressing surface which is porous so that delamination of the web is inhibited.

摘要： A coating apparatus and method is disclosed for applying coating material onto a web supported by a backing member. The apparatus includes a housing which is disposed closely adjacent to the backing member. The arrangement is such that the web supported by the backing member moves between the backing member and the housing. The housing defines a chamber having an open end facing towards the backing member. A coating shoe slidably cooperates with the web, the shoe being movably disposed within the chamber. The shoe defines a cavity which is connected to a source of pressurized coating material. The cavity has an exposed face towards the web such that the coating material flows into the cavity and through the exposed face for applying the material onto the web.

摘要： A press apparatus is disclosed for removing fluid from a fibrous web. The apparatus includes a press member and a blanket cooperating with the press member for defining therebetween an elongate pressing section such that the web is pressed between the press member and the blanket during passage through the pressing section. The blanket is urged towards the press member such that when the web passes through the pressing section, fluid is pressed from the web. A heating device is disposed adjacent to the press roll for transferring heat to the web such that when the web passes through the pressing section, the web is subjected for an extended period to increased pressure and temperature so that water vapor generated within the pressing section during the passage of the web through the pressing section forces the fluid in the liquid phase away from the web.

摘要： A short dwell coater apparatus is disclosed for coating a web with a coating material, the web moving contiguously with a rotating backing roll. The apparatus includes a housing which is disposed on the opposite side of the web relative to the backing roll. The housing defines a chamber is connected to a pressurized source of coating material. The chamber is exposed to the web such that the web supported by the backing roll is coated with the coating material during passage of the web past the coating chamber. Each of a first and second weir extend in a cross-machine direction such that the coating chamber is bounded by the weirs and the web moving between the weirs. The first and second weirs define respectively first and second overflow gaps. The arrangement is such that during use of the apparatus, when the web moves past the coating chamber, coating material is coated onto the web while excess coating material overflows through the first and second gaps for recirculating through the coating chamber. A resilient blade is disposed downstream relative to the second weir. The blade cooperates with the coating material coated onto the web such that the pressure exerted by the coating material on the blade is less than the pressure of the coating material within the coating chamber, so that mottling and streaking of the resultant web is inhibited while maintaining minimum pressure on the blade.
