Fourth Generation Family Business


Compan founder Hermann Wimmer

In 1903, Hermann Wimmer founded Piassavawerke Hermann Wimmer in Rüsselsheim. After a car factory was built there, the Piassavawerke suffered from a shortage of labour. This forced the founder to relocate his business. The brush manufacturer moved his business to his birthplace of Kappelrodeck, where it soon flourished.

Kurt Roß

After the death of Hermann Wimmer at the age of 83, his son-in-law Kurt Roß took over the company in 1958. Together with Hermann Wimmer, he had managed the company for many years.
The sons of Hansi Wimmer-Roß and Kurt Roß, Günter and Hans-Peter Roß, joined the brush production in 1963 and 1967 respectively after completing their studies and took over the management of the company in 1968 after the death of Kurt Roß.

Günter Roß und Andreas Ross

After the sudden death of Hans-Peter Ross in 1976, Günter Ross became the sole owner and managing director of Piassavawerke. In 2002, he handed over the company to his son Andreas Ross.




Production Methods


Produktion einer Kehrwalze

From manual labour, which was the only production method when the company was founded, the company has developed into a large machine park with refined production processes for the wide range of special brushes. Most of the brushes are produced on modern machines, some of which were developed in-house.

The possibilities of technologisation, mechanisation and computerisation of the workplace have always been taken up by Hermann Wimmer and tested for their integration into the production processes. For example, at times a steam engine was used to generate electricity for the company and in 1969 Wimmer was the first company in the Achertal valley to use electronic data processing to optimise administration. However, manual labour was not completely eliminated from the company. Even today, there are still operations that cannot be performed efficiently by machines. For example, the steel wires of the disc brooms are inserted into the disc broom bodies by hand by dedicated women.
