A small trading company for vulcanizing tyres is set up in Bad Wildungen, Germany.
In 1949, the company starts manufacturing rubber balls and balloons. At the end of the year, one of the staff comes up with an idea to manufacture foam rubber shoulder pads, which were popular in America at the time.
The Korrekta company is established at the beginning of the year. The name is derived from the shoulder pads made of latex foam and used for posture correction.
Production of these latex products starts in May 1950 in buildings once owned by Henschel aircraft engine manufacturers in Wega.
Ties are established with the Bayer dye works. A decision is made to start production of polyurethane foams. At the same time, construction begins on the first atomization system for foam plastic.
The plant is taken over by a subsidiary of the Quandt Group and the company name is changed to Correcta-Werke GmbH.
In May 1958, the Quandt Group transfers shares of Correcta-Werke GmbH to Kaus, the majority owner of Metzeler AG.

Along with all other Bayer Group insulation material operations, the Biedensteg plant is allocated to the Reinhold & Mahla company in Mannheim.
In 1983, the Biedensteg site becomes the parent company of Reinhold & Mahla and operates under the name Vereinigte Kunststoff AG Reinhold & Mahla Werk Correcta.
In 1985, the plant is transformed into an independent subsidiary of Bayer AG. The company once again goes by the name Correcta.
Correcta is acquired by the Illbruck family from Leverkusen on 1 October 1992 and integrated into the Illbruck Group as an independent business unit in 1998.
