摘要： An improved method and apparatus for substantially eliminating non-uniform charge patterns from a surface of a corona-treated web, particularly for enhancing the surface''s coatability, is disclosed. The improved method and apparatus employs the technique of ''''flooding'''' the surface with charge of one polarity from a first electrode so as to generally uniformly charge the surface, and thereafter removing the charge imparted to the surface by applying an equal but opposite charge from a second electrode. To ensure positive control between the amount of charge added to the surface and the amount removed, the invention proposes that the first and second electrodes be connected to a single source of DC power and that the web, when treated in accordance with the invention, be supported by an electrically conductive roller which is electrically isolated from ground.

摘要： A web with a plastic surface is dislcosed as being exposed to an a.c.-produced corona thereby to increase its printability and coatability. As a result of such treatment the web surface undesirably acquires patterns of charge. A circuit technique is disclosed for so erasing such charge patterns that the web surface is assuredly left substantially uncharged.

摘要： AN IMPROVED METHOD FOR SUBSTANTIALLY ELIMINATING CHARGE FROM A SURFACE OF A CORONA-TREATED WEB, PARTICULARLY FOR ENHANCING THE SURFACE''S COATABILITY. THE IMPROVED METHOD EMPLOYS THE TECHNIQUE OF "FLOODING" THE SURFACE WITH CHARGE OF A FIRST POLARITY SO AS TO GENERALLY UNIFORMLY CHARGE THE SURFACE AND THEREAFTER REMOVING THE CHARGE IMPARTED TO THE SURFACE, SO AS TO LEAVE THE SURFACE GENERALLY FREE OF CHARGE. TO ENSURE POSITIVE CONTROL BETWEEN THE AMOUNT OF CHARGE ADDED TO THE SURFACE AND THE AMOUNT REMOVED, THE INVENTION PROVIDES THE IMPROVEMENT OF MONITORING THE SURFACE OF THE WEB FOR CHARGE VARIATION AND FOR NTE CHARGE. THE AMOUNT OF CHARGE ADDED TO AND/OR THE AMOUNT OF CHARGE REMOVED FROM THE SURFACE MAY BE SO CONTROLLED THAT THE CHARGE VARIATION AND THE NET CHARGE ON THE SURFACE IS LOWERED TO AN ACCEPTABLE LEVEL, PREFERABLY APPROXIMATELY ZERO.
