With the onset of mass production in the automotive industry after the First World War, it became uneconomical for the industry to paint vehicle bodies manually, so paint spraying technology became established in America for the first time.
Richard Curt Walther from Wuppertal came into contact with the new technology in his function as general agent of the Leipzig Tangier Werke and recognized the potential of spraying technology. He then founded the "Spritzapparate und Maschinenbauanstalt" in Wuppertal-Vohwinkel in 1923, where he developed and marketed high-quality spraying tools.
