Abstract
The treatment of a material web (2) ensues in a U-shaped shaft comprising two shaft limbs (3, 4) and a connecting area (5) between both the shaft limbs. The shaft is filled with a treatment liquid, the feed of fresh treatment liquid and also the circulation of treatment liquid ensuing beneath the surface of the liquor within the shaft limb. The effect is a particularly intensive charging of the material web, with extremely economic use of treatment liquid. Foaming of the treatment liquid is prevented, also in the case of heavy turbulence.
