A brave young entrepreneur believes in the commercial success of cardboard. A family of entrepreneurs takes over and develops the company over the course of several generations into a worldwide technology group…
Heinrich Weidmann acquires the old water-powered town mill in Rapperswil (CH) and establishes a pressboard and cardboard factory. He starts supplying insulating materials to the still young electrical industry. His company grows successfully.1877
Heinrich Weidmann dies. His company is bequeathed to his two leading managers, who transform it into a joint stock corporation (“H. Weidmann Aktiengesellschaft”). The ailing company builds a modern industrial production and office complex.1914
Close to bankruptcy, the company is acquired by a financial consortium under the leadership of Jean Tschudi–Klaesi, the co-owner of a board mill in Ennenda, Canton of Glarus. Tschudi & Cie AG produces specialty boards for non-electrical applications; in particular stereotype matrix boards (later on also products for office supplies).1923
The necessary restructuring and leadership is entrusted to Jean Tschudi’s son, paper engineer Hans Tschudi–Faude. He positions H. Weidmann AG as a first class supplier of cellulose-based specialty boards and components for the power transformer industry (today: Business Area Electrical Technology, or ETBA).1925
First production of insulation components from calendered pressboard.1930
Plastic resin compounds, in particular Bakelite, have become fashionable. Weidmann is one of the first companies in Switzerland using this base material in compression molding to manufacture machine parts for the textile industry. The fabrication of molded parts for industrial application from thermosetting materials and thermoplastics constitute the Business Area Plastics Technology (PTBA).
Hans Tschudi invents “Transformerboard” (hot press-dried insulation board mainly used for transformer insulation).1937
During the Second World War, when export of high voltage insulation collapses, Weidmann survives thanks to its booming Plastics Technology, producing components from rifle shafts to housings for the domestic telecommunications industry.1939-45
Hans Tschudi travels to the USA to buy the first injection molding machine.1948
An important breakthrough in Electrical Technology is achieved by installing Weidmann’s first large size (3x6m) Transformerboard (T IV) machine in Rapperswil.1952
Dr. Felix Tschudi-Hubacher assumes management responsibility from his father.
Convinced that export alone will not satisfy growing customer demand, Felix Tschudi starts an ambitious international expansion program for the Business Area Electrical Technology (then: High Voltage Insulation).
Tschudi & Cie AG is integrated in the Weidmann organization.
