Abstract: An apparatus for tanning or dyeing includes a horizontal rotary drum which is rotatably mounted in a frame at only one axle front end thereof. The rotary drum defines a treatment chamber for tanning and dyeing which communicates with a hollow axle for admission and drainage of a liquid treatment medium. Within the interior of the rotary drum, at least two ring pocket sections are provided which are in communication with two connecting lines arranged at the axial front end of the rotary drum and extending in radial direction. With their radially external ends, each connecting line opens into the interior of the associated ring pocket section. The other end of each connecting line extends to the center of the rotary drum which center communicates with associated axial channels within the hollow axle.

Abstract: 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.
