  • Patent number: 4922627
    Abstract: The invention consists of modified dryer section in a papermachine wherein elements normally found in the press section of the machine are included in the dryer section. The modification consists of the use of a press felt instead of a dryer felt and the addition of press rolls, adjacent to the dryer cylinders, forming nips through which the felt and the wet paper sheet to be dried are passed. Pocket ventilation rolls are also included to evaporate water absorbed by the felt from the paper sheet during passages through the nips. The dryer section incorporating these modifications can be viewed as a press-dryer hybrid. Improved dryer efficiency and lower costs per ton of paper produced are the results.
