The Rheology of Calendering

  • R. S. Lenk

Abstract

Assuming the melt to be in laminar flow, a complete analysis would answer the following questions: Given the material constants, the geometry of the equipment and the selected operating variables, what will be:
  1. (i)

    the thickness of the foil or sheet produced;

     
  2. (ii)

    the temperature distribution in the material;

     
  3. (iii)

    the rate of draw through the roll nip;

     
  4. (iv)

    the force which tends to separate the rolls and acts on the calender bearings; (v) the power required to work the calender.
