Zusammenfassung:	PCT No. PCT/GB87/00455 Sec. 371 Date May 6, 1988 Sec. 102(e) Date May 6, 1988 PCT Filed Jun. 26, 1987 PCT Pub. No. WO88/00256 PCT Pub. Date Jan. 14, 1988.In an high speed electro-coating apparatus having a plurality of electro-coating cells (96) arranged around the periphery of a rotatable turnable (14), each can (128) is placed upright on a cell lid (100) below a hollow cell body (94) and is introduced into that body (94) by upward movement of the cell lid (100). Separate simultaneous flows of electro-coating fluid fill and immerse the can (128), and each cell (96) receives electro-coating current pulses via slip-ring segments (272-278) carried on the turnable (14) past respective sets of brushes (286) which are disposed at the respective electro-coating stations. Control apparatus (300,302) is arranged to feed current to the brush sets only during the periods of turntable rotation during which each brush (286) has full contact with an adjacent slip-ring segment (278) and for as long as such full contact is maintained.
