ABSTRACT:
In the method described, a compound substantially in the form of a paste is fed by means of a pump from a storage container (1) to a metering device (3) which determines the amount of paste to be applied to a workpiece (B). From the metering device, the paste is fed to a spray head (S) where it is [mixed with] swirled by compressed air from a cylinder (4) or other suitable supply and sprayed on to the workpiece (B). The amount of compressed air supplied to the paste for spraying purposes is controlled by means of a control unit (6) in such a way that a strip of substantially constant width is applied to the workpiece (B).
