ABSTRACT:
A method and apparatus for correcting the curl in drying and dried paper is presented wherein high velocity hoods are used in combination with drying cylinders. In addition, the use of impingement drying hoods provide a means to correct for variations in the moisture profile of the paper. High velocity hoods can be located in the drying section of a paper machine to compensate for uneven drying by paper cylinders.
