发明名称 APPARATUS AND METHOD FOR REMOVING FLUID FROM A FIBROUS WEB
摘要 An apparatus 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 press 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 pressing section, the web is subjected for an extended period to increase 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. The press member has an outer surface which cooperates with the web. The outer surface of the press member defines a plurality of grooves having a width within the range 1 to 1,000 microns for the reception therein of steam and water expelled from the web during passage of the web through the pressing section.
