Summary:PCT No. PCT/EP88/01070 Sec. 371 Date Aug. 31, 1990 Sec. 102(e) Date Aug. 31, 1990 PCT Filed Nov. 24, 1988 PCT Pub. No. WO89/06352 PCT Pub. Date Jul. 13, 1989.The invention relates to a process and device for measuring the effective viscosity and the elastic properties of coatings. Known measuring processes and measuring devices based on the "rolling ball method" suffer from drawbacks, namely run formation and sinking of the relatively heavy solvent vapors, due to the inclination of the coated sheet metal. To overcome these drawbacks, rolling movements are imparted to a magnetizable ball (1) displaced from its rest position in a magnetic field, during movement of the horizontally disposed substrate, under the influence of the field gradient of a permanent magnet or electromagnet (4) located below the substrate. The rolling movements are used as the basis for the measurements.
