Abstract

A process for coating, in particular for painting, individual objects or small-series batches with a small quantity of paint uses a plurality of atomizers 2, 3, 4 connected one behind the other to a main supply line 5, at one end/start 6 of which a paint-supply unit 7 is arranged. Only the quantity of paint which is required for the painting job and an additional minimal residual quantity are introduced into the main supply line 5, irrespective of the length and the actual capacity of the main supply line 5, e.g. a paint quantity less than the volume capacity of the main supply line. The contents of the main supply line 5 are forced, by at least one pig 32, which is pushed through the line 5 by a pushing medium, to the atomizers 2, 3, 4, and the contents are then at least substantially completely discharged there.
