NEWS20 CPI %u2013 Concrete Plant International %u2013 6 | 2025 www.cpi-worldwide.comThe success story of Paul Maschinenfabrik began in 1925, when Max Paul set up a mechanical workshop in his father's house in D%u00fcrmentingen. In 1953, Paul entered the field of prestressed concrete technology. This was followed in 1959 by the first single-wire stressing jack with the then revolutionary two-button operation. By 1965, the company had grown to 120 employees and 4,500 m%u00b2 of production space. Important innovations at this time included the Tensa SM stressing process (1960) and the Tensa M multi-stressing jack (1970). In the mid-1970s, part of the production was relocated to Riedlingen.The 1980s were characterised by automation. Among other things, Paul developed the first automatic button heading machine for railway sleepers (1989). The prestressed concrete department expanded its portfolio with multi-stressing jacks for cable-stayed bridges (1982).In the 1990s, Paul set standards with innovations such as the first stressing robot for railway sleepers. In 1995, the company employed 245 people on 21,000 m%u00b2 and also developed a multi-stressing jack for ram piles. In 1997, Paul played a key role in the reconstruction of the Frauenkirche in Dresden - with specially developed prestressing technology. As capacities at the parent plant in D%u00fcrmentingen were exhausted, Paul began building a new plant in its own industrial estate in 1999.The turn of the millenniumThe new plant was completed for the company's 75th anniversary in 2000. At the same time, the prestressed concrete department developed the TensaControl measuring and logging system. Both plants now employed around 270 people and the production area had expanded to 30,000 m%u00b2.In 2010, the plant in D%u00fcrmentingen was expanded again and reached an area of 37,000 m%u00b2. In 2016, the largest multi-stressing jack with a force of 22,000 kN was delivered. In 2017, Paul developed a process for the automatic control of button heads, which was submitted for the concrete components supplier industry innovation award. In 2019, the Tiny Tensa Control, a tablet-based logging system for the production of prestressed precast concrete parts, was introduced.100 years of Paul MaschinenfabrikFrom a passionate innovator to a leading force of prestressed concrete technologyOrigin of the Paul Maschinenfabrik in D%u00fcrmentingen (1925) Company founder Max Paul
