Abstract
1,035,407. Electrotypes. NICKELOID Ltd. June 15, 1965 [June 22, 1964], No. 25762/64. Heading B6C. An electrotype shell 5 is backed by electrodepositing a metal or metal alloy 6 directly on the rear of the shell whilst the shell is still on the mould 3. A nickel copper shell 5 is electrodeposited on the mould 3 which has been sprayed with silver, and a first backing layer 6 of lead tin alloy containing a little copper is electro-deposited on the shell. The backed shell and mould are then rinsed and dried, and the layer 6 is shaved at the back to remove most of it adjacent to the non-printing areas 5a of the electro. A second layer 7 of backing alloy is now deposited on the layer 6. After further rinsing and drying and after removal of the mould 3, the backing 7 is shaved to a plane surface. More than two operations of backing and shaving may be employed. Finally, an aluminium sheet 8, Fig. 9 (not shown), is secured by adhesive 9 to the plane surface of backing 7.
