Abstract:
A process for electrochemically treating a continuous web moving through an electrolyte solution contained in a treating line tank the steps of the process comprising:providing at least one electrode positioned adjacent at least one surface of the continuous web moving through the electrolyte solution, said at least one electrode extending across a width of the continuous web; providing at least one rigid, non-flexible, and non-conductive bumper device extending across and contacting the entire width of said at least one surface of the continuous web moving through the electrolyte solution; maintaining said continuous web in a pass-line position through the electrolyte solution by positioning said at least one bumper device against the entire width of said at least one surface of the continuous web; and causing said least one surface of the continuous web to slide against a surface of said at least one bumper device, said continuous web moving along said pass-line position through the electrolyte solution so that said least one surface of the continuous web is electrochemically treated.
