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。

In this manner, the at least one concentration of the at least one material suspension supply is adjusted. At least one second control loop is provided that is adapted to regulate the concentration of the material suspension supply. The method includes determining a basis weight at an end of the manufacturing process, calculating a deviation of the determined basis weight from a predetermined target value, adjusting a concentration of a material suspension supplied to a headbox via a first control loop such that the calculated deviation is corrected, one of directly and indirectly measuring a basis weight of a resulting web in a region upstream, with regard to a web travel direction, a drying section, and supplying a signal related to the measured basis weight to a second control loop.

摘要： A headbox includes a feed device feeding the fibrous material suspension, a nozzle, and a turbulence-generating device. The fibrous material suspension is guided in the turbulence-generating device in sub-flows through turbulence-generating channels. Within the individual turbulence-generating channel of the turbulence-generating device, at least one region forming a fluidization region is provided, in which a pressure loss can be generated in the sub-flow of the fibrous material suspension guided through said region. The nozzle and the turbulence-generating device are designed and dimensioned such that they are suitable for setting a dwell time of ≦200 ms of the fibrous material suspension flowing through the same from a final fluidization region of an individual turbulence-generating channel before inlet into the nozzle as far as the outlet gap of the nozzle, and a pressure loss of ≧50 mbar in the final fluidization region upstream of the inlet into the nozzle.
