ABSTRACT:
A rotary brush for applying paint to surfaces comprises a housing, a rotatable hollow cylindrical body which bears on the cylindrical surface a plurality of brush units, motor means, passage means for supplying paint from a supply channel to the bristles of the brush units, and a number of stationary guide rings mounted rigidly in the housing and guidingly surrounding the rotatable cylindrical body. The guide rings are disposed in zones transverse to the axis of the cylindrical body and distributed over the length of the same. Each ring bears a slidable bearing means adapted for bearing, for instance with a loose wheel at its free end, against the surface to be painted, thus relieving pressure of the bristles on the surface to be painted.
