The biggest turning lathe for pieces of 2,000 mm diameter is taken into operation.
Johannes Buch takes over as the sole managing director in 5th generation in 1997.
Construction of a new production hall for the casting of calender rolls. A new grinder and a deep-hole drilling bench guarantee that the roll foundry is fully prepared to meet the requirements of the plastics, rubber and paper industries.
The first roll production by means of a vertical spin caster marks the start of a new era.
1957 – 1960
A large bay for machining purposes and a new laboratory building are erected.
The foundry is newly designed and enlarged. The melting shop is converted into electric furnaces and coal dust furnaces.

Fritz Hermann Buch is appointed second managing director; he will decisively influence the expansion and reconstruction of the company.
The machine casting business is given up, KARL BUCH specializes exclusively in roll production.
On the premises acquired from the abandoned neighboring iron and steel plant “Rolandshütte” a new roll grinding shop is built. The turning shop is expanded in order to machine rolls up to 60,000 kg.
The company gets its own railway connection and the power supply is provided by the power plant „Elektrizitätswerk Siegerland“.
Fritz Buch, the son of Friedrich Buch, gathers from the USA the idea to add alloying metals to the rolls. With this new technique Fritz Buch opens the door to the global market.
With the construction of the first chemical laboratory a new era starts in the roll foundry; experience is completed by scientific research. Now it is possible to produce rolls with a finished weight of up to 40,000 kg.
For the first time the foundry produces more rolls than machine castings. 2,700 tons of rolls weighing between 150 and 30,000 kg are produced and only 766 tons of machine castings.
The foundry expands its casting and machining capacities.
Production starts in the new roll foundry.
Friedrich and Heinrich Buch, the successors of Karl Buch, lay the cornerstone for the construction of a new roll foundry.
A new and expanded foundry starts its production in Weidenau.
Karl Buch acquires a first small iron foundry with cupola furnace.
The first bigger roll is supplied, a grooved roll of 1,500 pounds.
Karl Buch founds the enterprise; in the beginning the melt was bought from the “Tiefenbacher Hütte“ and directly cast on site into molds produced by himself.
