摘要

Improvements introduced in tunnels for the treatment of pieces, characterized by the fact that they form two watertight compartments in their entirety, separating the traction elements and mechanisms with the treatment chamber from the piece to be treated, this piece being suspended by means of an arm, of adequate silhouette, of the upper compartment or mechanisms; this arm crosses the watertight separation due to its silhouette and to the interruption of the separation partition that constitutes two independent lips.
