SYSTEM FOR REDUCING BLISTERING OF A WET PAPER WEB ON A YANKEE DRYER

摘要

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).
