Abstract

1,067,685. Abrading. R. V. MULLER. Oct. 1, 1964 [Oct. 4, 1963], No. 40026/64. Heading B3D. Cathode material for electrolytic condensers is made by increasing the effective surface area of foil by treating with a rotating element consisting of an open tri-dimensional network of mutually bonded synthetic fibres, the volume of which amounts to less than 25% of the total volume of the element, in which an abrasive is embedded. Foil from a roll 2 passes round roller 6, guide rollers 5, 4 and roller 7 to take-up roll 3, so that both faces of the foil are treated by an element 8 having a diameter of about 180 mm. and rotated at about 2500 R.P.M. The foil moves at about 10 mm./sec. The element 8 may be as described in Specification 884,204. When the foil is aluminium, aluminium oxide is used as the abrasive.
