Roller Traction A Model for Web Traction Over Non-Vented Rollers!

In this paper you will review models and an optimization technique where the results will indicate the viability and utility of the new product. The models and technique include:

  • A mathematical model that couples air film pressure, web deflection, and asperity deformations is used to model the web/roller interface.
  • An optimization technique is used to estimate the asperity compliance function parameters based on the experimental results and the mathematical model.
  • A new model for determining the asperity engagement height, for surfaces with non-Gaussian peak height distribution, is proposed when the roughness of both surfaces is taken into account.
