Wrinking from roll diameter variationsReduce Wide Web Wrinkling!

Interested in reducing wide web wrinkling?  This paper will review the results from wide web wrinkling including:

  • Wide web wrinkling due to roller misalignment for various materials and compare the experimental wrinkling results to isolated-span shear wrinkle models.
  • Share results from over ten different roller designs (including various concave roller profiles) demonstrating their relative effectiveness in preventing shear wrinkles and their ability to spread a web slit down its center.
  • Provide the results of an experiment investigation to eliminate wrinkles and an upgraded model to predict wrinkles caused by roller deflection in the negative bow direction.
