    • Experimental and theoretical study of web traction over a nonvented roller 

      Rice, B. S.; Cole, K. A.; Muftu, S. (Oklahoma State University, 1999-06)
      The traction developed between a thin flexible web, wrapped around a nonvented, rotating cylindrical roller is studied experimentally and theoretically. A series of eight webs representing a wide range of surface roughness ...
    • Simple model to predict web-to-roller traction 

      Rice, B. S.; Gans, R. F. (Oklahoma State University, 2003-06)
      We have studied the traction developed between a thin, flexible web and a rotating cylindrical roller. We present a new analytic model for high-wrap, circumferentially grooved rollers that couples air film pressure, web ...
    • Two-dimensional model to predict web-to-roller traction at small wrap angles 

      Rice, B. S.; Gans, R. F. (Oklahoma State University, 2003-06)
      We have studied the traction developed between a thin, flexible web and a rotating circumferentially grooved cylindrical roller. The traction model developed by Rice and Gans [1] is inadequate for small wrap angles, because ...
    • 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, ...
