Abstract

The method for the supply of colour to an electrostatic coating device (3) involves coating material flowing from a container (12A,12B) in a potential isolating unit (1) connected to a colour supply unit (10) lying on an earth potential to the coating device via a connecting line arrangement (2). The container is connected directly to the colour supply valve (10A,10B) of the colour in use. The container is movable back and forth by an automatic drive unit between the colour supply valves and a colour extraction valve (14A,14B) to which is connected the connecting line (2A,2B) leading to the coating device. Independent claims are also included for the following: (a) a unit for the supply of colour to an electrostatic coating device; and (b) a connecting device for the aforesaid colour supply unit.
