Abstract

1366316 Electro-forming brass cylinders RANK XEROX Ltd 25 Jan 1972 [25 Jan 1971] 3058/71 Heading C7B Brass cylinders for conductive endless flexible belts in xerographic copying machines are electro-formed by electro-plating a brass coating e.g. 75 to 125 microns thick on to a cathode former e.g. a stainless steel cylinder 13 rotated e.g. by drive rod 11 in a brass plating bath at a surface peripheral velocity of at least 30 cm., preferably 323 to 395 cm. per second. The plating current may be periodically reversed. The plating bath may comprise 25 to 40 g/l Cu, 2À4 to 3.4 g/l Zn, 40 to 75 g/l Na 2 CO 3 , 4.4 to 10 g/l free CN, 1À5 to 10 g/l free OH, and have a pH of 12. Electrical connection is made between the cylinder 13 supported between PTFE discs 14, 15 and the rod 11 by metal springs 16. The anode plates 4 are of brass. The electrolyte 1 may be heated by external heater 3 and recirculated within the tank 2 using a circulator supplying a rectangular loop feed pipe 8.
