    • Measurement of web feed rates in rubber covered nip roller applications and the impact on wrinkle formation 

      Cole, K. A.; Walker, T. J. (Oklahoma State University, 2011-06)
      Nip rollers are used extensively in web handling processes; however, rubber-covered rollers have the unwanted and often unpredictable characteristic of unknown surface speed owing to coupling between circumferential and ...

    • Practice application and design of concave rollers 

      Walker, T. J. (Oklahoma State University, 2007-06)
