The device for tanning, dyeing or the like, comprises a horizontal rotary drum mounted on a hollow shaft and having a cylindrical drum jacket, which is sealed at the front ends by means of closing walls and contains in its interior a tanning or dyeing compartment subdivided into three treatment chambers by means of three perforated equiangularly spaced radial partition walls. The rotary drum comprises on its exterior a number of pockets corresponding to the number of the treatment chambers, each pocket being in joint communication with respectively two treatment chambers. During the rotation of the rotary drum in one direction of rotation the treatment medium emerges approximately radially from a treatment chamber and enters a pocket in the area of one frontal drum end from which a partial stream flows into another pocket to be mixed with the treatment medium disposed in this pocket and then approximately radially into a treatment chamber. The other partial stream flows simultaneously to the opposite drum end into an associated pocket, is mixed with the treatment medium contained therein, and flows from this pocket approximately inwards into the same treatment chamber. Rotation of the rotary drum in the direction of rotation opposite thereto causes a corresponding scooping of the treatment medium to occur at the other frontal drum end and in the opposite flow direction.
