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.

Abstract: A surface treater system for three dimensional articles, especially elongated articles such as wires, cables and the like, increases the surface tension of the articles and thereby can be used to clean, etch and improve the wettabliity of the surface for inks, dyes, adhesives and the like. The treated article is supported by one or more guides that guide it through a long, narrow treatment zone. Two or more elongated electrodes are arranged in the treater to ionize working media within the treatment zone. The working media can be diffused and injected evenly along the entire length of the treatment zone to ensure consistent treatment along a long length of the treated article. An elongated barrier member can be provided to contain the working media in the treatment zone. Alternatively, working media can be injected and diffused from multiple, preferably opposing, sides of the treatment zone to further contain and disperse the working media, and provide essentially full-periphery surface treatment.
