    • Wound-in-tension in a non-woven web 

      Balaji, K. K.; Good, J. K. (Oklahoma State University, 2005-06)
      Literature on wound roll structure of non-homogeneous webs is scarce. Experimental and analytical research on wound roll structure of homogeneous materials such as plastic films and paper has been reported extensively, ...

    • Wound-on-tension for two drum winders 

      Good, J. K.; Cowen, B. R.; Dolezal, L. E.; Markum, R. (Oklahoma State University, 2003-06)
      The two drum winder remains to be a high productivity winder for rewinding some paper and nonwoven webs at very high speeds. Winding models of varied capabilities exist for center winders, center winders with rider rollers, ...

    • Wrinkle dependency on web roller slip 

      Dobbs, J. N.; Kedl, D. M. (Oklahoma State University, 1995-06)
      The shear forces in a web introduced from an untrammed roller create wrinkles that are affected by web twisting or slipping on the upstream roller. The web span bounded between the untrammed and upstream rollers behaves ...

    • 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 ...

    • Wrinkle-free conveyance in nips 

      Rice, B. S. (Oklahoma State University, 2005-06)
      Wrinkling in nips with ultra-thin webs is empirically studied. In web converting, nips are used for tension isolation drives, gravure coaters, prevention of air entrainment on rollers and winding rolls, calendaring, ...

    • Wrinkling mechanisms of webs with spatially varying material properties 

      Carrle, Jeremy; Lange, Steve; Hamm, Rich; Ba, Shan (Oklahoma State University, 2017-06)
      Webs often include variation in caliper or modulus of elasticity as a result of manufacturing variation. Light-weight nonwoven webs are especially prone to these issues because the variation is proportionally more, relative ...

    • Wrinkling of foils 

      Walker, T. J.; Cole, K. A.; Zagar, S.; Quass, J. (Oklahoma State University, 2011-06)
      Aluminum and copper metal webs less than 150 microns (6-mils) are considered foils. Demand for aluminum and copper foils are growing, driven by growing markets for flexible electronics, flat panel displays, lithium batteries, ...

    • Wrinkling of webs due to twist 

      Good, J. K.; Straughan, P. (Oklahoma State University, 1999-06)
      Webs are often required to endure twisting in web process machinery. There is a limit to the degree to which the web can be twisted prior to wrinkling. The objective of this publication is to document a closed form technique ...

    • Wrinkling of webs on rollers and drums 

      Jones, D. P.; McCann, M. J. (Oklahoma State University, 2005-06)
      Wrinkles are frequently observed in thin webs wrapping rollers, winding cores, and drums in vacuum coaters. They are the buckling response of the web to compressive deformation in the transverse direction (TD), which may ...

    • Wrinkling of wide webs 

      Walker, T. J.; Cole, K. A. (Oklahoma State University, 2011-06)
      Wrinkling remains one of the top causes of converting process waste. Though wrinkles created by roller misalignment and web bending (shear wrinkles) are well-understood, nearly all the published research and modeling has ...
