Abstract
The purpose of the invention is a treatment unit for a band product (2) comprising at least one extant treatment tub (1) connected to a mechanism (B) for controlling the running of the band product (2) inside the extant tub (1). The at least one extant treatment tub (1) is connected to at least one replacement tub (4) made of an oblong enclosure provided above the extant tub (1) and exhibiting a height (h) lower than the height (H) of the extant tub (1). The replacement tub (4) is associated with an apparatus for injecting the liquid and to the mechanism (B,B') for controlling the running of the band, so that the product (2) runs inside the replacement tub (4) in contact with the treatment liquid (A).
