<p>A unit (100') for treating containers (101), comprising at least one station (103) with a bath (103B) for a treating medium, the bath (103B) being defined by non-deformable walls (103W) and comprising a horseshoeshaped recess (110) for lodging a first driving wheel (109B) of transport means (106) adapted to advance containers (101) along a path (P) across the bath (103B); the U-shaped recess (110) comprising a semicircular portion (111) with diameter D SC ; the transport means (106) comprising at least a second driving wheel (109A) arranged downstream of said first driving wheel (109B) with respect to a direction of advancement of said containers (101) along said container path (P); the at least one first driving wheel (109B) having a diameter D B substantially equal to the diameter D SC of the semicircular portion (111) and smaller than the diameter D A of the at least one second driving wheel (109A); the at least one first driving wheel (109B) being borne by a driving shaft (112B) having a diameter d B smaller than the diameter d A of a driving shaft (112A) of the at least one second driving wheel (109A); the difference (D SC - d B ) substantially matching the difference (D A - d A ) and twice the height (H) of the containers (101) to be treated.</p> |
