Press section paper machine

The Press Section is the second key stage in the paper machine process, where the wet paper web from the forming section is mechanically dewatered by pressing it between rollers. This significantly reduces moisture content and improves sheet strength, smoothness, and bonding before it enters the drying section.

• Function:
  • Mechanically removes 40–50% of water from the wet paper web
  • Increases sheet density and improves fiber bonding
  • Prepares the web for efficient drying in the next stage

• Main Components:
  • Press Rolls: Hard and soft rolls arranged in pairs to apply pressure
  • Press Felts: Absorb water squeezed out of the sheet
  • Suction Press Roll (optional): Enhances water removal through vacuum
  • Pick-up Roll: Transfers the web from the forming section
  • Drive System: Controls press speed and nip pressure
  • Guide & Stretching Systems: Maintain felt tension and alignment

• Types of Press Configurations:
  • Single Press
  • Double Press
  • Triple Press
  • Shoe Press (for high-speed and high-quality production)

• Features:
  • Improves paper sheet strength and surface finish
  • Optimized nip pressure for different paper grades
  • Reduced steam consumption in the drying section
  • Long-life felts with high water absorption capacity
  • Stainless steel or coated rolls for durability
