History of the screen..................
The oldest screens known consisted of wooden bars and finer screens of horse hair. The first exact proof for the use of wire as grids dates back to 1556, these were used to process ore. The first patents for this purpose were registered in France in 1821.
Louis Herrmann in Dresden specialised in producing industrial screens from 1938. The company was a pioneer in the development of screening processes and was destroyed in the Second World War. After the war, Hein Lehmann was able to take over the most important employees after the collapse and subsequently all the rights and experience.
Isenmann, founded in 1949 was taken over by Hein Lehmann in the mid 50's and thus was able to share Hein Lehmann's wealth of experience.
The plastic material, polyurethane was developed by Bayer with the basic patents dating back to 1937. The raw material basis of polyurethane materials is crude oil; the

The first polyurethane screens were manufactured in the mid 60's with Isenmann manufacturing polyurethane screens from 1973 with the introduction of stretched tensioned versions, flat versions, flat screen panels in frames and system screen panels.
The interchangeable screen system was introduced in 1978 with the WS 43 system, followed by WS 80 in 1980, WS 83 in 1983 and WS 85 in 1984 resulting in a very successful screening system backed by a great deal of experience. Further developments are centred around this system with its typical dimensions.
Tema UK was established in Banbury in 1961 with Isenmann establishing themselves in Blaby, Leicestershire in 1985. In 1990 Tema moved to a 1000 sq metre site at Woodford Halse, Northants.
