    • Behavior of a flexible web in contact with a roller 

      Jones, Dilwyn P. (Oklahoma State University, 2013-06)
      In the contact patch between a web and a roller, there may be regions of stick and microslip or full slip. Within the stick zone, the velocities of web and roller surface match, but in the microslip zone they differ by a ...

    • Dimensional stability of substrates for printed electronics 

      Jones, Dilwyn P. (Oklahoma State University, 2015-06)
      Substrates for flexible displays must retain registration between multiple process steps. Although polyester substrates offer cost and handling advantages, their dimensions are affected by tension, temperature and humidity. ...

    • New model for the steady state deformation and friction of webs on rollers 

      Jones, Dilwyn P. (Oklahoma State University, 2017-06)
      A web moving through process machinery interacts with rollers through frictional forces, which may change its direction of motion and tension. By modelling the web as a beam, these forces can be calculated from its tension, ...

    • Web sag and the effect of camber on steering 

      Jones, Dilwyn P. (Oklahoma State University, 2007-06)
      A web in a horizontal span will deflect downwards due to gravity. This sag is more pronounced for heavy materials in long spans under low tension. It is possible for a web whose unstretched length is greater than the span ...

    • Wrinkle initiation and development in heated webs on drums 

      Jones, Dilwyn P.; McCann, Michael J.; Bishop, Charles A.; Abbott, Steven (Oklahoma State University, 2013-06)
      Wrinkles often occur in webs heated on drums and rollers. Anecdotal evidence from vacuum metalizers suggests that wrinkles are initiated by small grit particles or surface imperfections that lift the web off the drum. An ...
