A Field-Replaceable Composite Roll system (FRCR) consists of a complex composite cover and a unique mechanical mounting system, configured to allow the retrofit of existing silicone sleeved rolls, as well as manufacture new rolls, at substantially lower costs. The system of the present invention can be used for retrofitting existing dead-shaft or live-shaft rolls previously manufactured to use silicone sleeves, as well as fabricating new rolls in conjunction with the patented WINERTIA brand tubing or conventional thin-walled tubing. The exemplary embodiment of the composite cover is fabricated of a filament wound tube bound together via a resin or the like having dielectric properties, the tube forming inner and outer walls, the inner wall coated with a conductive layer for receiving and conducting an electric current, the outer wall coated with a wear resistant layer (illustrated as ceramic coating), followed by a sealant layer. The composite cover is configured to slide over and envelope a roller body, and be anchored in place via mechanical mount formed of first and second expansion rings and associated compression bases.

A manually switchable corona electrode array and method of operation for use in a corona treater station. The preferred embodiment of the present invention contemplates an electrode array which incorporates in its structure a low pressure conduit system for providing a low pressure field in the vicinity of the corona field, in order to remove ozone and other contaminants generated by the corona field. The electrode array further includes means to quickly and easily urge the array from a first position, wherein the array is situated adjacent to the treatment area, to a second position, removed from the treatment area, so as to facilitate maintenance and spooling of the material to the treated therethrough. The present invention provides a more compact footprint than traditional systems, as well as providing an ozone removal system requiring a cheaper, less powerful exhaust blower for providing the low pressure differential to remove the pollutants, including ozone, from the treatment area. Lastly, the design of the present invention provides a unique cooling system, utilizing the circulation of air through the electrodes in removing the pollutants in order to cool the electrodes, so as to prevent thermal overload.
