Abstract: A method and apparatus are taught for treating paper webs for obtaining the proper surface characteristics to promote adhesion of nonphotosensitive coating materials and/or layers typically coated thereon. The web is passed through a high-voltage sheath region or dark space of the plasma generated by a powered electrode residing in a discharge zone. The frequency of the driving voltage must be above a lower bound dictated by the properties of the paper support and the plasma, and it must be below an upper bound beyond which the sheath voltages drop significantly and it is observed that the benefits of this approach diminish. The dark space is generated by a treatment electrode in a treatment zone. There is a counter electrode having a surface area in said treatment zone which is at least as great as the surface area of the treatment electrode.

Abstract: A vacuum lubricant deposition station coats a lubricant onto the back side of a moving web prior to coating the front side with emulsions. The deposition station has a sidewall creating a chamber containing a heat source along its bottom and an evaporating tray above the heater which holds the lubricant to be vacuum vapor deposited on the web. A water cooled jacket fits about the top of the sidewall and receives the film through a narrow slot between its top and bottom plates to expose the back side of the film to a vapor cloud of lubricant in the chamber. Lubricant from the cloud deposits on the back side of the web. Stray lubricant from the cloud condenses on the bottom plate which receives cooling water through an inlet. The cooling water traverses the length of the bottom plate, enters the top plate through a water loop connecting the top and bottom plates, and exits through the top plate. The vapor cloud condenses on the bottom plate before reaching the front side of the film.
