摘要： A drying section for a paper making machine. The drying section includes a plurality of single-tier dryer groups, optionally followed by one or more double-tier groups. To control curl in the final paper product, a moistening device extending over the width of the drying section is provided near the end of the single-tier dryer groups. The moistening device can be divided into various zones to control the profile of the paper. Alternatively, or in addition to the moistening device, a contact-less dryer such as a infrared dryer can be provided after the dryer section, upstream of a calender section of the paper making machine. The moistening device can be provided to moisten the bottom or, optionally, the top side of the paper web. Where a double-tier dryer group is provided, to control curl the upper drying cylinders and the lower cylinders can be provided with different steam pressures to control curl. Alternatively, each of the cylinders can be individually controlled. In accordance with a further embodiment, control of web curl is not accomplished in the main dryer section, but rather in an after dryer section which follows a device such as a coater, size press or the like which rewets the paper web.
摘要翻译：造纸机的干燥部。干燥部分包括多个单层干燥器组，任选地后跟一个或多个双层组。为了控制最终纸制品中的卷曲，在单层干燥器组的端部附近提供在干燥部分的宽度上延伸的润湿装置。润湿装置可分为多个区域以控制纸张的轮廓。或者，除了润湿装置之外，还可以在造纸机的压延部之后的干燥部之后设置无接触干燥机，例如红外线干燥机。可以提供润湿装置以润湿纸幅的底部或可选地上部。在提供双层干燥器组的情况下，为了控制上部干燥筒的卷曲，并且下部气缸可以具有不同的蒸汽压力以控制卷曲。或者，可以单独控制每个气缸。根据另一实施例，在主干燥器部分中不能实现卷材卷曲的控制，而是在后面的烘干部分之后，该烘干部分跟随诸如涂布机，压榨机等的装置，其重新润湿纸幅。

摘要： The paper dryer section has a single tier of all top felted dryer rolls seven to nine feet in diameter. Air caps are employed over the dryer rolls to simultaneously dry both sides of the web to prevent curl and to increase drying rates. The air caps employ blown air at a temperature of 200-1,000 degrees Fahrenheit and air speeds of 8,000-40,000 feet per minute. The felt employed is foraminous with a permeability of between 300-1,500 cubic feet per minute per square foot and is designed to withstand peak temperatures of up to 1,000 degrees Fahrenheit and average temperatures of between 500-600 degrees Fahrenheit. A single dryer roll, or more advantageously, two vacuum rolls in a vacuum box are disposed between the dryer rolls to maximize the circumferential wrap of the web and, at the same time, support and transport the web between dryers.

摘要： Blistering of a wet paper web upon a yankee dryer drum is controlled by directing compressed dry air toward the wet paper web in the space between a pressure roll external of the yankee dryer hood and the entry opening between the dryer hood and the yankee dryer drum. The flow of compressed air is controlled so that air flow can be modified across the full width of the wet paper web.

摘要： The dry end of a paper machine comprises a first dryer group with top drying cylinders, with a first drying wire and with bottom deflection suction rolls. Adjacent this, there is a second dryer group with bottom drying cylinders, with a second drying screen and with top deflection suction rolls. In this way, both sides of the web to be dried come, in succession, into direct contact with the drying cylinders. At the place where the web changes from the first drying wire to the second drying wire, there is a transfer suction roll which lies within the loop of the second support belt. The web travels there from the last cylinder of the first dryer group over an at least approximately straight travel path to the transfer suction roll and thus onto the second support belt.

摘要： A dryer section of a paper machine including cylinder groups provided with single-wire draw having smooth-faced heated drying cylinders against which a web to be dried enters into direct contact, and reversing rolls. The groups with single-wire draw have a drying wire which is guided in a loop by guide rolls as well as by the drying cylinders and the reversing rolls so that the drying cylinders are placed outside the wire loop, and the reversing rolls are situated in gaps between the drying cylinders inside the drying-wire loop. In order to optimize the drying capacity calculated per unit of length of the dryer section in the machine direction, as the drying makes progress, a different ratio of the drying cylinder diameter to the reversing roll diameter is employed, so that, in the first group or groups in the initial end of the dryer section, the ratio is higher than the corresponding ratio in the groups in the middle area of the dryer section. In the group or groups in the final end of the dryer section, a diameter ratio is used that is higher than the ratio in the middle area of the dryer section.

摘要： A method and apparatus for ventilating pocket spaces in a multi-cylinder dryer of a paper machine, in particular a high-speed paper machine whose running speed is higher than about 800 meters per minute, in the area of a so-called twin-wire draw. In the twin-wire draw, the drying cylinders in the drying group are arranged in two rows placed one above the other, in which rows the successive cylinders are placed in the upper row and in the lower row as interlocked. In each cylinder group, there are two drying wires, an upper wire and a lower wire for pressing the paper web against heated faces of the drying cylinder while being guided by guide rolls placed in gaps between the cylinders. The paper web runs as free draws between the rows of cylinders. Pocket spaces are formed in the area between the free draws of the web and the upper wire and its guide roll and the drying cylinder in the lower row and, in a corresponding manner, adjacent pocket spaces are formed in the area between the free draws of the web, the lower wire, its guide roll, and the drying cylinder in the upper row. The pocket spaces are ventilated by pumping air induced by the wire in the multi-cylinder dryer, wherein, at the inlet side of the guide roll, the wire pumps air into the pocket spaces through the wire and wherein the wire pumps air out of the pocket spaces at the outlet side of the guide roll of the wire. Air being pumped out through the wire on its run at the outlet side from the guide roll to the following cylinder is limited as compared with free pumping-in and pumping-out so as to control the pressure level and/or the flow status in the pocket spaces.
