    • Effects of air entrainment on vacuum drive roller traction 

      Dobbs, J. N. (Oklahoma State University, 2001-06)
      Vacuum assisted drive rollers are commonly used to provide additional traction in web tension control schemes. Single-sided web contact makes them a natural choice between a coating station and an oven where lower tensions ...

    • Measurement and modeling of bearing drag in idler rollers 

      Dobbs, J. N.; Kedl, D. M. (Oklahoma State University, 1997-06)
      Idler roller bearing drag plays a critical role when modeling web tension in a web line system. Lubrication, line speed, radial and axial loads on bearings can influence drag, which is directly reflected as a tension load ...
