  • Method for warming up or cooling down a through-air dryer
    Patent number: 8176650
    Abstract: A through-air dryer system that diverts the airflow within the through-air dryer during warm up and cool down from the normal airflow during the drying of paper in the papermaking process. During warm up and cool down, a majority of the airflow is supplied to one of the dryer's heads and extracted through the opposite head to reduce thermal stresses. If needed to further reduce thermal stresses, a minority of the airflow is supplied through the dryer's shell.
    Type: Grant
    Filed: December 13, 2005
    Date of Patent: May 15, 2012
    Assignee: Kimberly-Clark Worldwide, Inc.
    Inventors: Frank S. Hada, Robert J. Seymour, Marek Parszewski
