    • Air entrainment during film winding with layon rolls 

      Forrest, A. W., Jr. (Oklahoma State University, 1995-06)
      Excessive air entrainment has long been recognized as a cause for telescoping and other forms of wound roll defects. To eliminate a portion of the air, exclusion devices such as layon rolls are often used. Air entrainment ...

    • Wound roll stress analysis including air entrainment and the formation of roll defects 

      Forrest, A. W., Jr. (Oklahoma State University, 1995-06)
      Numerous procedures have been developed to determine the stresses inside wound rolls of film. These typically use factors such as winding tension, film thickness and film properties to calculate the stresses. The calculation ...
