Establishment of Gummiwerk KRAIBURG GmbH & Co. KG. The history of Gummiwerk KRAIBURG began on October 22, 1947. In that year, Friedrich Schmidt senior began producing rubber compounds in Kraiburg – Hart, using rather limited resources and operating under very difficult conditions. While the beginnings of Gummiwerk KRAIBURG are rather humble, a solid foundation was laid for the future success of the KRAIBURG Group. Thanks to the tireless work and commitment of the founder’s sons Peter and Fritz A. Schmidt, sales and production increased year on year.
