摘要： A compact multilevel paper making machine is provided comprising a web-receiving region where a web of paper is received on a fabric forming a continuous loop, a reel-up for winding the paper web onto a roll, and a web transfer point disposed between the web-receiving region and the reel-up. The fabric receives the web at the web-receiving region and then supports and transports the web from the web-receiving region to the web transfer point in a first direction on a first defined vertical level. At the web transfer point, the web is separated from the fabric. The fabric loop further includes a return run from the web transfer point to the web-receiving region over which the fabric then travels. A cleaning section is also disposed along the return run of the fabric loop for cleaning the fabric. Following separation from the fabric, the web is transported to the reel-up in a second direction, generally opposite to the first direction, and on a second defined vertical level different from the first defined vertical level. The second defined vertical level may be either above or below the first defined vertical level, wherein a defined vertical level may comprise, for instance, a floor of a building. Dryers are also provided before and/or after the web transfer region for drying the web and are accordingly disposed on the different defined vertical levels. Thus, by configuring the paper making machine to transport the web between different defined vertical levels, a compact multilevel paper making machine having a small footprint is provided for limited-space installations.
摘要翻译：提供了一种紧凑的多层造纸机，其包括纸幅接收区域，其中纸幅被接收在形成连续回路的织物上，用于将纸幅卷绕到卷筒上的卷取机和布置在纸幅接收区域之间的纸幅传送点网络接收区域和卷轴。织物在纸幅接收区域处接收纸幅，然后在第一定义的垂直水平上沿着第一方向将纸幅从纸幅接收区域支撑并传送到纸张传送点。在纸张转印点，纸幅与织物分离。织物循环还包括从织物转移点到织物接收区域的返回流动，织物随后通过该区域行进。清洁部分也沿着织物环的返回路径布置，以清洁织物。在与织物分离之后，幅材沿着与第一方向大体相反的第二方向以及与第一限定垂直水平不同的第二限定垂直水平传送到卷取机。第二定义的垂直水平可以高于或低于第一定义的垂直水平，其中定义的垂直水平可以包括例如建筑物的楼层。也可以在幅材转印区域之前和/或之后提供干燥器，用于干燥纸幅，并且因此将其设置在不同的限定垂直水平上。因此，通过配置造纸机在不同的定义的垂直水平之间输送纸幅，为有限空间的装置提供了一种占地面积小的紧凑型多层造纸机。

摘要： A pulp drying line which comprises a pulp press for pre-drying the pulp and a defibrator for shredding the pre-dried pulp into a loose pulp. The drying line further comprises a web forming section and a pulp dryer section. The loose pulp coming from the defibrator is spread in the web forming section in a layer on an air-permeable forming base, from which the air-permeable pulp web thus formed is taken through the dryer section supported by an air-permeable support fabric, such as a wire. The pulp is not formed into a pulp web during pre-drying.

摘要： The present invention is an apparatus for maximizing water removal from an absorbent web in a press nip. The present invention uses a pressing unit with a pressure profile that maximizes water removal in the press section or on the Yankee dryer of a paper machine. The pressure profile of the pressing unit according to the present invention has a very steep pressure drop at and/or following the exit of a pressure distribution curve in order to maximize water removal by minimizing rewet of the web. The improved pressure profile according to the present invention results in increased water removal and/or improved line speed.

摘要： A through-air drying paper making apparatus is provided comprising a twin-fabric forming section, a water-removing section arranged downstream of the forming section, and a web transfer device disposed between the forming section and the water-removing section. The forming section includes a forming roll, a pair of fabrics guided to travel about a portion of the circumference of the forming roll, and a headbox operable to deposit a slurry between the fabrics so as to form a paper web therebetween. Preferably, one of the fabrics in the forming section comprises a through-air drying (TAD) fabric arranged to carry the paper web through the water-removing section, while the other fabric comprises a forming wire. At the web transfer device, the paper web is separated from the forming wire and the paper web then carried on the TAD fabric through the water-removing section. The water-removing section includes at least one through-air dryer for at least partially drying the paper web. Most preferably, the forming section and the web transfer device are arranged such that the forming wire and the TAD fabric, with the paper web sandwiched therebetween, travel along a substantially straight and relatively short path between the forming roll and the web transfer device, thereby resulting in minimal directional change of the paper web after formation thereof about the forming roll and prior to separation of the paper web from the forming wire. An associated method is also provided.

摘要： A paper machine for manufacturing a structured soft paper web are described, which machine has a wet section, a press section, a drying section and a web-carrying clothing running around a suction device close to a smooth impermeable belt in the press section for the creation of a transfer point. In accordance with the invention, structuring means for structuring the web are arranged between the press section and the drying section. The structuring means comprise either said clothing in the shape of a permeable wire, the structure of which is made up of depressions and arched surface parts, including knuckles in a quantity of 25-150 knuckles per cm2, and a suction device that, at a vacuum of 40-80 kPa, draws the web to the structured side of the wire so that the web acquires the structure of the wire, wherein the wire operates at a speed less than or equal to the speed of the belt, or a creping doctor that is located in a space between the belt and the clothing and in scraping contact with the belt so as to loose the web during simultaneous crinkling, the suction device having a suction gap for initial suction of the web firmly to the clothing for transfer to a drying cylinder. The web-carrying clothing operates then at a speed that is less than the speed of the belt.
