Date Apr. 18, 1991.Method and apparatus for the continuous treatment of reduced thickness article surfaces, for example, for the surface treatment of fragile products of small dimensions. The product to be treated is continuously poured, along with a treatment product, if necessary, into a rotary cylinder arranged horizontally or substantially horizontally, and rotated at low speed. A helical brush is also rotated at a reduced speed in an opposite direction to the cylinder, with the brush being arranged parallel to the cylinder and in contact on at least one of its generating lines with at least one internal generating line of the lower portion of the cylinder.
