Blistering of a wet paper web (32) upon a yankee dryer drum (10) is controlled by directing compressed dry air toward the wet paper web (32) in the space between a pressure roll (30) external of the yankee dryer hood (12) and the entry opening (22) between the dryer hood (12) and the yankee dryer drum (10). The flow of compressed air is controlled so that the air flow can be modified across the full width of the wet paper web (32).
On élimine la formation de boursouflures sur une bande (32) de papier mouillé se trouvant sur le tambour (10) d'un sécheur frictionneur en dirigeant de l'air sec comprimé sur la bande (32) de papier mouillé dans l'espace situé entre un rouleau de compression (30) externe par rapport au capot (12) du sécheur frictionneur et l'ouverture d'entrée (22) située entre le capot (12) de sécheur et le tambour (10) du sécheur frictionneur. Le flux d'air comprimé est régulé de manière à pouvoir être modifié sur toute la largeur de la bande de papier mouillé (32).
