DIENES – a company with tradition

DIENES Apparatebau GmbH is a company with tradition and experience founded in 1930 by Fritz DIENES in Mühlheim am Main. DIENES started through the production of electrical toys with heating applications during the economic boom years. The main focus was directed towards the development and implementation of small and medium-sized heaters and radiant heaters for industrial use.


The quality and reliability of the DIENES-products enabled the development of new markets. In the late 1950s, the relations with the textile industry in Frankfurt was prepared. This settled close cooperation for ground-breaking developments in the upcoming years. Starting with a view on industrial switchboards, very soon special adapted control systems were implemented for the textile industry.

Building on the experience gained from the early years DIENES researched increasingly on heating technologies situated in the formation of manufacturing processes of yarns and chemical fibers. This led to the implementation of heating processes for the production of polyamide fibers – better known today under the trade names Nylon or Perlon.

In this time bases were created which formed the foundation for further development and construction on heating apparatus and control units as well as godets and thread guides. Soon DIENES equipped complete draw zones, draw wind and draw twist machines with inductive heated rollers, heat plates and tube heaters.

The 1980s under the direction of Wolfgang Gehrmann and Max Broßmer were marked by further advancements caused by the increasing demand for fibers. The size of DIENES godets was enlarged and the temperature accuracy improved. 1988 DIENES introduced the first multi zone induction heated godet which set a standard in polyamide and polyester spinning mills. Furthermore the precision of DIENES heating tubes used for texturing processes build up a worldwide reputation. The product range of DIENES was extended further by the introduction of the contact less signal transmitter system Rototronik®. This was an essential step for the improvement of DIENES godets.

By the early 1990s DIENES presented the All-In-One godet, which was a pioneering integration of mechanics and electronics. This machine was integrated in numerous spinning machines worldwide until today.

Today DIENES is not only a specialist for godets, heaters and controls but also able through their close cooperation with partners to supply complete systems including the technical process part. The DIENES MultiMode® installations enable researchers and process developers to improve textile processes with a great precision steadily.

The research department of DIENES permanently develops products from the standard scope of supply and allows the mechanical and thermal treatment of industrial yarns, films and tapes made of new materials by performance limits which are raised frequently. Thus, they can provide thermal treatments today at temperatures up to 700°C and can cover complex drives with a speed range of 0.1 – 8,000 m / min.

Customers rely worldwide on the longstanding experience of DIENES. As a partner for machine components for the synthetic fiber production as well as textile special applications, we are ready for your tasks.
