(54) Process and apparatus for the preparation of materials to be subjected to finishing treatments


(57) Process for the treatment of materials to be subjected to finishing processes, in particular for the pre-treatment of metallic and non metallic materials which comprises the treatment of said materials with appropriate substances, normally fluids, in suitable containment baths equipped with devices able to confer kinetic energy to said fluids, said baths being equipped with appropriate two-way sections formed within their interior and thus allowing the complete recycling of the fluids involved, their mixing, possible filtering, and passage at high speed on the materials to be treated.
