Abstract
A coating material is transferred to the surface of a spreader-roll from a spreader-mechanism. The spreader-roll is partly wrapped by a strip of material. In the location where the said strip of material is lifted off the spreader-roll, a doctor-element, comprising a doctor-blade, is arranged to rest tangentially on the spreader-roll. The doctor-element thereby forms a rubbing distributing surface which faces the strip of material and ensures a smooth and uniform coating of the coating material on the strip of material. The strip of material is then carried away over a sharp tear-off edge on the doctor-element at an angle of less than 20.degree.. In this way a coating of any desired thickness may be applied to a strip of material, more particularly as a coating for a strip of paper.
