About the sound
The “Tumble-wash” (manufacturer unknown) from the 1920s was originally used in the wire-making industry in the city of Altena (Southern Westphalia) in Germany. The machine served the purpose of removing the layer of cinder from the wire, which arises from the manufacturing process. The cinder is a consequence of the repeated heating of the wire. In order to remove the cinder, the wire is placed in a device which moves up and down, causing the wire to pound against the bottom. This causes the „tumbling“(Germ.: Poltern) sound which gives the process its name.
Today the “tumble-wash” can be found at the German Wire Museum in Altena. It is turned on for demonstrational purposes.
