  • Patent number: 10744545
    Abstract: The disclosure relates to a continuous cleaning method for cleaning a moving fabric in a paper machine. The method uses one or more cleaning stages. In one embodiment, one cleaning stage applies steam to heat and soften contaminants on the fabric followed by the application of water, preferably superheated water, to remove the contaminants. Another cleaning stage may apply hot water, steam and/or superheated water via an encapsulated shower and evacuation chamber making it possible to clean the width of the fabric without substantial rewet.

  • Publication number: 20170218569
    Abstract: Described herein are methods and systems for reducing, preventing, or eliminating wrinkles in a paper sheet during papermaking. The systems may include a dryer configured to dry a continuous paper sheet having a travel direction. The system may also include at least one roll configured to receive the dried continuous paper sheet. The systems may also include an air spreader located downstream of the dryer and upstream of the at least one roll. The at least one roll may include one or more calendering rolls. The air spreader may include a plurality of nozzles configured to expel a gas toward the dried sheet. The nozzles may be oriented in a direction at least partially opposed to the travel direction of the dried sheet.
