Vacuum Couch Roll for Kraft Paper Machine

The vacuum couch roll is positioned after the press section of the machine and before the dryer section. As the wet paper web passes over the roll, the vacuum system sucks water through the wire mesh and out of the paper , helping to remove moisture and increase the paper’s dryness.

The vacuum couch roll is also important for maintaining the web’s surface quality and eliminating wrinkles or creases that may occur during the paper-making process. It plays a critical role in ensuring the paper is of high quality and meets the required specifications.
