The bubble sucker in the press section provides for a stable web run and reduces or eliminates blistering of the paper web before its entry into the press nip.
By means of an ejector effect, the bubble sucker generates a vacuum of up to -150 Pa under the press felt in the stabilization zone. This enables a stable and crease-free web run, and the frequency of breaks is noticeably reduced.
Creation and maintenance of the vacuum in the entire stabilization zone is achieved by blowing air at high speed in the nozzle geometries at the entry and outlet and by means of side air knives on the bubble sucker. The vacuum can be set manually by means of a hand flap in the air supply duct. The design of the bubble sucker is easy to maintain.
