Abstract: The present invention relates to a machine for the continuous treatment of a body of revolution. Treatment stations are provided on the periphery of a rotatable drum. The machine comprises at the location of the zone of treatment a continuous guiding belt driven by a prime mover. On one side or the other of such belt, or on both sides thereof, there are disposed elements constituting a fixed guiding guard. The drum drives the bodies of revolution which are to be treated, in rotation by friction as they pass along the guard and the belt, the treating operation being effected when the treatment stations and the bodies pass through the zone of treatment. The bodies can themselves turn, if the drum is stopped, by friction between them and the movable belt, in order to avoid defects in varnishing or other similar treatments in case of breakdown of the driving of the drum. The apparatus is particularly useful in the continuous varnishing of bodies of revolution.
