Abstract: A device for chemically treating leather and the like has a housing and a rotary drum. The housing has an opening opposite an open end of the drum. A double-walled door closes the opening and its interior communicates with a channel in the housing and with the interior of the drum, respectively.

Abstract: A cleaning chamber and a separate spaced-apart drying chamber are provided, which communicate with one another. Articles are cleaned in the cleaning chamber while the same is out of communication with the drying chamber. Then the communication between the chambers are established and the cleaned articles are transported from the cleaning chamber into the drying chamber with a stream of air circulating in a closed path. After this, the communication between the chambers is interrupted and the thus-transported articles are dried in the drying chamber. A transport conduit communicates the chambers with one another, and a flap located in the former is operative for closing and opening the transport conduit. An air passage additionally communicates the chambers with one another, and an air impeller causes air to travel into the cleaning chamber to thereby transport the articles from the same, and to travel into the drying chamber to thereby dry the articles.
