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.
