Edge brush for electroplated strip

Apparatus for removing excess plated metal from the narrow face of the edges of electroplated metal strip as the strip travels through a strip processing line, said apparatus comprising:

• a brush;
• a carriage for supporting said brush, said carriage being slidably movable in a transverse direction with respect to the strip,
• means mounted on said carriage for rotatably driving said brush,
• means for slidably moving said carriage inwardly and permitting movement outwardly in said transverse direction to maintain said brush in contact with the narrow face of said strip edge and so that said brush exerts substantially constant pressure thereagainst,
• said brush comprising a cup having an outer cylindrical surface and filaments extending longitudinally along an inner face of said outer cylindrical surface so as to extend beyond an exposed edge thereof, said brush being rotatably driven about a central longitudinal axis of said cup, a cover mounted over said brush, a collection tank connected to said cover, and means for exhausting gas from said cover and collecting particles of plated metal in the tank as they are removed from the strip by the brush.
