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.
