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.

A device that attaches to a standard fabric compactor and allows narrow collar material to be processed through the standard fabric compactor. The device includes a pair of air openers. Each air opener includes an air inlet assembly and an air outlet assembly. The air inlet assembly of each air opener pulls air therein to form pulled air and pressurizes the pulled air to form pressurized air. The air outlet assembly of each air opener fluidly communicates with the air inlet assembly of an associated air opener, receives the narrow collar material therethrough, receives the pressurized air from the air inlet assembly of the associated air opener, and directs the pressurized air onto the narrow collar material, simultaneously from above and below, and in doing so, suspends the narrow collar material allowing the narrow collar material to be processed through the standard fabric compactor.
