Research & Development, Department of Analytical Measurements, Venlo, The Netherlands ABSTRACT The rolling contact of cylinders coated with a rubber layer is studied. The rubber layer consists of one or more sublayers with different elastic and geometrical properties. Each sublayer may be viscoelastic. The numerical results are verified by experiments. A contactless measurement technique, Laser-Doppler Anemometry, is applied to measure the velocity in and outside the contact region. INTRODUCTION The frictional contact between rolling cylinders coated with one or more rubber layers has many applications in industry. For example in copiers these mechanical elements (or nips) frequently occur and are
