Claim:
1. An apparatus for coating the surface of cylindrical articles comprising: a detachable coating member comprising at least two rotating rollers which can congruently annularly encompass the periphery of a cylindrical article to be treated; a mechanism for detaching the coating member; a feeding system of the coating material into coating member, wherein each of the rollers are executed with an inner cavity and its walls are permeable to the coating material, providing delivery of the latter from the inner cavity of the roller onto the treated surface, and has a channel for feeding coating material into the inner cavity, in that it further comprises a rollers rotation actuator; a carriage and at least two arcuate brackets movably joined to the carriage; the rollers are designed to be capable of bending easily in any direction and to have high torsional stiffness and low bending stiffness, where one end of each roller is rotatably fastened to the carriage and is connected by a spindle to the rotary actuator, the other end of each roller is rotatably fastened to a free end of an arcuate bracket; the brackets are mounted on the carriage with a distance therebetween sufficient to accommodate the cross-section of the article to be treated and are capable of rotating towards one another in a mutually perpendicular manner and capable of enclosing the cross-section of the cylindrical article in a semi-circular manner.
