摘要： Drying section of a machine for producing a material web. The drying section includes a support roll with an associated impingement dryer, and at least one straight or curved section forming at least a part of a closed path between a last nip of a press section adjacent the drying section and the support roll. The support roll and the impingement dryer are arranged to guide the material web over the support roll, and, thereby, to subject the material web to at least one of hot air and hot steam impingement. The at least one straight or slightly curved section is structured and arranged to form at least one of an impingement drying section and a transfer foil section.

摘要： A dryer section of a paper or board making machine has a plurality of dryers. In a first group of dryers, each dryer heats the web somewhat more, but not to the level of the maximum evaporation rate of the moisture contained in the web. As the web is passing the end of the first group, the web is heated to such a high temperature that it reaches the maximum evaporation rate of the moisture in the web. The dryers in the first group have smaller diameters, which may gradually increase up to the region of the maximum evaporation rate, or they may all be of one smaller size. The dryer section has a second group of dryers in which each dryer heats the web to the maximum evaporation rate of the moisture contained in the web. The dryer at the beginning of the second group has the largest diameter. The following dryers in that group can have a smaller diameter. The dryers in the second group may be grouped in groups of decreasing size, or may gradually decrease in size. Advantageously, each group of dryers (A,B) is divided into subgroups (A.sub.1 ; A.sub.2 ; B.sub.1 ; B.sub.2 ; B.sub.3 ; B.sub.4) wherein first, one side of the web contacts all the dryers of one subgroup (for example A.sub.1), and then the other side of the web contacts all the dryers in the next subgroup (for example A.sub.2), and each subgroup is associated with one and only one fabric belt such as a felt or wire.

摘要： An apparatus in the dryer section of a paper or board making machine, wherein the section has a plurality of dryers. There is an initial region of dryers, each of which heats the web somewhat more, but not to the level of the maximum evaporation rate of the moisture contained in the web. It is not until the web is passing the end of said initial region that the web is heated to such a high temperature that it reaches the maximum evaporation rate of moisture in the web. The dryers of the initial region have smaller diameters, which may gradually increase up to the region of maximum evaporation rate, or they may all be of one smaller size. Following the initial region the dryer section has a region of dryers in which each dryer heats the web to the maximum evaporation rate of the moisture contained in the web. The dryer at the beginning of that regions has the largest diameter. The following dryers in that region may have a small diameter, because with less remaining moisture in the web, the web needs to contact each succeeding dryer for a decreasing length of time to still reach the maximum evaporation rate of moisture. The dryers in the region of maximum evaporation rate may gradually decrease in size, or may be grouped in groups of decreasing size.

摘要翻译： 纸或纸板制造机的干燥部中的装置，其中该部分具有多个干燥器。 存在干燥器的初始区域，每个干燥器的每一个都稍微加热幅材，但是不能达到包含在幅材中的水分的最大蒸发速率的水平。 直到网状物通过所述初始区域的末端，即网状物被加热到如此高的温度，使其达到网状物中最大的水分蒸发速率。 初始区域的干燥器具有较小的直径，其可以逐渐增加到最大蒸发速率的区域，或者它们都可以是一个较小的尺寸。 在初始区域之后，干燥器部分具有干燥器的区域，其中每个干燥器将幅材加热到包含在幅材中的水分的最大蒸发速率。 该区域开始时的干燥器具有最大的直径。 该区域中的以下干燥器可能具有小的直径，因为在幅材中较少的剩余水分，纤维网需要接触每个随后的干燥器减少长度的时间，以达到最大的湿度蒸发速率。 最大蒸发速率区域中的干燥器的尺寸可能逐渐减小，或者可以按尺寸减小的组分组。

摘要： A machine and method for producing a material web, e.g., a paper or cardboard web. The machine includes a dryer group having a plurality of dryer cylinders and web guide rolls. A dryer (or guide) belt may guide the material web around the dryer cylinders and web guide rolls in a meandering or winding path. The dryer group may include a cooling device that cools the dryer belt by exerting an air current on the dryer belt after separation from the material web. The method may include drying the material web in a region of the dryer group in which the material web is held and guided between the dryer belt and each drying cylinder, and substantially preventing drying of the material web in a region of the dryer group in which the material web is transferred from one drying cylinder onto a subsequent one.

摘要： A drying section for drying a traveling web of paper, which has successive drying groups each having drying cylinders, a felt or wire belt supporting the traveling web and resting against the drying cylinders, and guide rolls serving for the guiding of the web to be dried and of the felt or wire belt. The guide rolls are so arranged that the traveling web is guided in meandering form in the transfer region between two successive drying cylinders associated with different felt or wire belts. The transfer region is between the felts of two successive drying groups or the transfer region is between two felts in the two rows of a two tier drying group.
