Interested in understanding web traction over a nonvented roller?

You can find more information here.  The traction developed between a thin flexible web, wrapped around a nonvented, rotating cylindrical roller is studied experimentally and theoretically. A series of eight webs representing a wide range of surface roughness characteristics are traction tested against the same roller over a wide speed range. This paper includes a study that:

• Models a one-dimensional finite difference model that couples the following using an asperity complicance function to model the experimental traction data:
  
  • Air film pressure
  • Web bending
  • Solid-body contact
• Results are presented which indicate the viablility and utility of the new methods.
