Forming section for paper machine

The Forming Section is the first and most critical part of the paper machine where pulp slurry is transformed into a continuous sheet of paper. It plays a vital role in sheet formation, water removal, and fiber distribution, directly affecting the quality and properties of the final paper product.

• Function:
  • Converts pulp slurry into a uniform wet web
  • Initiates dewatering through gravity and vacuum
  • Controls fiber orientation, sheet thickness, and formation quality

• Main Components:
  • Headbox: Evenly distributes pulp slurry across the wire
  • Wire/Former Table: Moving mesh that supports water drainage
  • Table Rolls and Foils: Aid in water removal and web support
  • Vacuum Boxes: Enhance dewatering efficiency
  • Suction Couch Roll: Removes remaining water and transfers the web to the press section

• Types of Formers:
  • Fourdrinier (single wire)
  • Twin-wire (gap former or hybrid former)
  • Cylinder former

• Features:
  • High consistency and uniform sheet formation
  • Adjustable drainage elements for optimized control
  • Designed for various paper grades (writing, packaging, tissue, etc.)
  • Built with corrosion-resistant materials for long life
