    • Experimental study of idler roll slippage 

      Ries, J. P.; Farr, T. J. (Oklahoma State University, 1999-06)
      Idler roll slippage occurs when the roll surface velocity no longer equals the velocity of the web that transports the roll. In a web transport system, slippage will produce scratches in sensitive, coated web or cause ...

    • Experimental study of winding zone dynamics 

      Ries, J. P. (Oklahoma State University, 1997-06)
      The elastic nature of plastic films and the rotational inertia of rolls, spindles and drives cause a film handling line to exhibit the characteristics of a dynamic system. This dynamic response can be observed by measuring ...

    • Theoretical comparison of winding tension control methods 

      Ries, J. P. (Oklahoma State University, 1999-06)
      Several methods are used to control tension in the winding zone. The two most common methods use either a tension signal from a loadcell or a position signal from a dancer system. Both techniques control tension, however, ...

    • Web tension in a flotation dryer 

      Ries, J. P. (Oklahoma State University, 1997-06)
      In a flotation dryer, the web rides on a cushion of air and typically takes a "sine wave" path over the air bars. The non-straight path and the elastic effect of the air cushion interact with the normal tensioning of the ...
