Paper Machine Finishing

Calender Machine

A Calender is a series of rollers that press and smooth out the paper sheet to achieve the desired thickness, density and surface finish. Teh Calender is typically located after the press section and before the reel. Calendering smooths out the paper sheet, removing any wrinkles, air pockets or excess moisture. It normally consists of a series of rollers, typically2-4, arranged in a stack. The paper sheet passes through the calender, where it is subjected to high pressure and heat. This causes the fibers to bond together, resulting in a denser and smoother paper. By adjusting the calender's pressure, temperature and roller configuration, paper makers can achieve specific paper properties and qualities.

ADVANTAGES

  • Improves paper smoothness and gloss
  • Enhances printability and writability
  • Increases paper density and strength
  • Reduces paper thickness variations

TYPES OF CALENDER

  • Soft calendar: Uses soft, deformable rollers for gentle smoothing
  • Hard calendar: Uses hard, non-deformable rollers for intense smoothing
  • Multi-nip calendar: Uses multiple rollers with precise gap control for high-precision smoothing
