Tired of Gentle Wavy Defects in your Knurled Wound Rolls?

  • Presenting product and process information characterizing this situation along with potential theories as to the cause of the corrugations and GWDs
  • Providing results from numerious experiements that provide guidance on the likely mechanism responsible for the formation of the roll and web defects.
