Roll Type Patents (Class 68/97)
  • Patent number: 8709351
    Abstract: A continuous feed discharge surface treater for treating web materials has a discharge chamber where ionization of a process gas occurs defined and contained by one or more rollers. Enhanced chemical coronas and plasmas are achieved by limiting depletion of the gas chemistry from the discharge chamber and dilution or contamination from mixing with drawn in ambient air. Atmospheric coronas can also be achieved in which minimal or no ozone is exhausted from the treater. Various roller and electrode assemblies, including both fixed and rolling electrodes, can be employed.
