    Abstract: A drying section for a paper making machine includes a larger number of dryer sections, fewer dryers in each dryer section, and provisions for driving many of the dryers individually. The average number of dryers per dryer section is less than five and preferably less than four. By providing a small number of dryers per dryer section and driving many of the dryers individually, it is possible to more precisely compensate for stretching of the paper web in the initial stages of the drying process and to more precisely compensate for shrinkage of the paper web during the latter stages of the drying process.
