    摘要： In a drying section of a machine for producing a material web such as, in particular, a paper or cardboard web, a pick-up suction roll, in particular a larger pick-up suction roll, is provided between the last pressing nip of a pressing section and a subsequent impingement drying unit, which suction roll removes the material web from a pressing felt guided through the pressing nip or from a transfer belt and transfers it to the impingement drying unit.

    摘要： Process for conditioning a circulating felt belt of a machine, pipe suction apparatus and traversing pipe suction apparatus therefor, the process including performing a zonal conditioning of a plurality of zones across a width of the felt belt by measuring at least one of, fibrous material web cross direction profile; felt belt cross direction profile; and permeability of the felt belt across the width of at least one of the web and the belt. The felt belt is conditioned depending on measuring results obtained for a respective zone. The pipe suction apparatus includes a ceramic body extending at least essentially across the entire width of the felt belt, the ceramic body being provided with a slotted surface by way of which the felt belt is subjectable to vacuum, with a respective effective amount of slotted surface being zonally variably adjustable by way of movable tongues.

    摘要翻译： 用于调节机器的循环毛毡带，管道抽吸装置和横穿管吸入装置的方法，所述方法包括通过测量毛毯带的宽度上的多个区域的区域调节，通过测量纤维材料网 横向剖面; 毛毡带横向轮廓; 以及毡带穿过幅材和带中的至少一个的宽度的渗透性。 毛毡带根据对各个区域获得的测量结果进行调节。 管道抽吸装置包括陶瓷体，其至少基本上跨过毛毡带的整个宽度延伸，陶瓷体设置有开槽表面，通过该开槽表面，毡带可以受到真空的影响，相应有效量的开槽表面 通过可移动舌头可变地变化。

    摘要： Pressing arrangement having two press rolls forming at least one press nip for dewatering a web, and two dewatering belts arranged to be guided through the at least one press nip with the web. The dewatering belts positioned on opposite sides of the web to absorb water. A common guidance path, formed by the dewatering belts guiding the web, is located after the at least one press nip. A separating roll and a lower one of the dewatering belts is arranged to wrap the separating roll along with the web at an end of the common guidance path. An upper one of the dewatering belts is arranged to be guided away from the web in a separation path in a region of the separating roll. Lower dewatering belt and web wrap the separating roll subsequent to the separation path at a wrapping angle of at least about 30null.

    摘要翻译： 具有两个压榨辊的压制装置形成至少一个压榨辊隙，用于使纸幅脱水，以及两个脱水带，其布置成被引导通过带材的至少一个压榨压区。 位于纸幅相对两侧的脱水带吸收水分。 由引导幅材的脱水带形成的常见引导路径位于至少一个压榨压区之后。 分离辊和下部一个脱水带被布置成在共同的引导路径的一端包围分离辊以及幅材。 脱水带的上部被布置成在分离辊的区域中的分离路径中被引导离开卷筒纸。 较低的脱水带和纤维网以分离路径在至少约30°的缠绕角度之后包裹分离辊。
