Abstract: A method and device for creating markings of highly viscous marking material on a surface, in particular a road surface. The marking material is discharged from a material supply and, before striking the surface is fed to a rotational body, which moves relative to the surface in a longitudinal direction of the marking, and is applied to the surface divided into unequal material portions by the rotational body. The rotational body axis of rotation runs at right angles to the marking longitudinal direction. The marking material is fed to the rotational body in a plurality of marking material flows, which, viewed in a longitudinal direction of the rotational body, are discharged next to one another from a plurality of discharge nozzles continuously, pulsatingly or intermittently in a pressurized manner. The individual marking material flows are turned on or off in accordance with the marking to be created.

After the elapse of a fraction of the overall unbalance measuring time the unbalance measuring operation is interrupted for an interruption time for the purposes of permitting the performance of working operations which due to vibration caused thereby could result in falsification of the unbalance measurement results, then unbalance measurement is resumed, and further interrupted, and so on in a repetitive procedure to make up the overall measurement time.
