Sealing units

Stabilizers / sealing units in the dry section provide optimized web guidance in the particularly sensitive area of the first dry section in the paper machine. They selectively control and reduce the load placed on the yet-to-be-dried paper web as it is separated from the cylinder. As well as reducing the tension on the paper, the stabilizers / sealing units also increase the web path resistance to deviations in the humidity profile or minor disruptions within the edge section; the overall result being a quieter process and reduction in the number of tears. A reduction in paper web tension and increase in speed can be achieved simultaneously.

ROBATEC Twinseal sealing unit

Stabilizers / sealing units in the dry section for optimized web guidance in the particularly sensitive area of the first dry section in the paper machine.

  • Outstanding energy savings
  • Minimal investment costs
  • Simple installation – no modification required
  • Optimize web guidance – increased speed
  • Increased wire endurance thanks to contactless sealing
  • Easy to maintain and handle

Application

Web retainers / stabilizers in the dry section

OLD system vs. NEW system

The perfect sealing in the placement zone means that suction capacity is increased by up to 40% with the same vacuum. Modification is easy, cost-effective, and carried out onsite.

ROBATEC Multiseal sealing unit

Multiple sealing / stabilizers in the dry section for optimized web guidance in the particularly sensitive area of the first dry section in the paper machine.

  • Improved web placement and transfer through targeted vacuum
  • Constant sealing position saves energy
  • Increased wire endurance thanks to contactless sealing
  • Easy to maintain and handle
  • No modification required

Application

Web retainers / stabilizers in the dry section 

Special feature

Multiple lip seal, using ROBATEC Twinseal instead of PTFE strips.
This simple optimization of material immediately reduces the system's energy consumption and
increases the vacuum.
