<p>A plurality of electrical driving motors for the rolls in cooperative upper and lower tiers of a paper machine dryer section are coupled with respective dryer rolls in what may be a one-motor-to-one-roll relation, the rolls of each tier being wrapped and synchronized by a dryer felt for that tier. One of the motors of each tier is synchronized with one of the motors of the other tier for synchronizing the running speed of each roll tier with respect to the other roll tier.</p> |
