Abstract: The cleaning device for leather clothing parts (8), comprises a filter container (3) with an opening formed as inlet and outlet for the leather part, which is closely lockable with a cap, a controllable movement mechanism (5, 7) for moving the leather parts in the filter container, and a container (10) for a cleaning fluid (11) suitable for the leather cleaning. The container is connected over fluid lines (13, 15) and a controllable pumping device (14, 16). Cleaning cushions are contained in the filter container and consist of a sponge-like fluid reception, fluid storage and cushion bodies. The cleaning device for leather clothing parts (8), comprises a filter container (3) with an opening formed as inlet and outlet for the leather part, which is closely lockable with a cap, a controllable movement mechanism (5, 7) for moving the leather parts in the filter container, and a container (10) for a cleaning fluid (11) suitable for the leather cleaning. The container is connected over fluid lines (13, 15) and a controllable pumping device (14, 16). Cleaning cushions are contained in the filter container and consist of a sponge-like fluid reception, fluid storage and cushion bodies, which have rough external surface texture and deliver the liquid under mechanical load. During cleaning, the cleaning cushions with the stored cleaning liquid and with the leather part to be cleaned are moved by the movement mechanism into the filter container without the cleaning fluid. The cleaning takes place by a plant relative motion between the leather part and the cleaning cushions. A gas discharge opening is intended at the filter container in the upper area and through which the cleaning liquid, which is evaporated to cleaning agent gas during and/or after the cleaning procedure and/or after a drying procedure, is extracted by a dust collector using a gas exhaust pump. The dust collector is subordinated downstream to a condenser. The liquid outlet of the condenser is connected with the container for the cleaning fluid or with a receiving tank. A controllably propellable rolling drum is present as movement mechanism in the filter container with horizontal axis of rotation for the reception of leather part and the cleaning cushion. The cushion bodies consist of a nature sponge material and have a right parallelepiped form with length of 10 cm, width of 7 cm and height of 1 cm. The rough external surface texture is formed by a liquid-permeable cushion coat with rough external surface texture, in which the cushion bodies are inserted. The cushion coat is formed by fabrics or web with an outside knob or loop structure from flexible thread material or is stitched, sprayed or glued with a corresponding knob or loop structure on a textile substrate or is held together by textile threads. The thread material is a metal or a plastic wire or is formed by narrow foil strips made of metal or plastic material. A control equipment is intended, with which the cleaning liquid is pumped and injected on the cleaning cushions and excess cleaning liquid is evacuated, and with which the rolling drum and the gas exhaust pump are activated. The movement mechanism and the gas outlet are controllably switched off after the pre-selected cleaning time and drying time and the cleaned leather part is taken out from the filter container. An independent claim is included for a leather cleaning method using a leather cleaning device.
