    摘要: The invention is directed to a paper machine for the production of a fiber web, including a headbox for forming the fiber web. Disposed adjacent the headbox is either a dewatering unit, e.g., a dewatering cylinder, a double wire former or a four-drinier wire section. Also provided are at least one press unit for dewatering the fiber web, a tissue drying cylinder for finish drying the fiber web, a device for fiber web pickup from the tissue drying cylinder (Yankee cylinder), e.g., a creping doctor or a Clupak device, and a carrier belt for carrying the fiber web. At least one of the press units is configured as a shoe press for drying the fiber web, and includes a device for immediately separating the fiber web from a press felt after at least one press pass. The belt is preferably water impermeable, and an adhesion force between the water impermeable belt and the fiber web is greater than an adhesion force between the press felt and the fiber web.

    摘要: The press section of a paper machine for thin papers has the following characteristics: a pressing gap is formed by a rotary, smooth surface (1) in contact with the paper and by a felted pressing roll (3); the smooth surface (1) transfers the paper web downstream of the pressing gap to a heatable roll (4) without free pulling of the paper web. The invention is characterized in that the smooth surface (1) is the outer surface of a tubular roll with dimensionally stiff roll sleeve.
