Since it was founded in 1950 by Rudi Knopp, we are experts in machines for glass and metal processing. Not only does passion distinguish us, but also 65 years of experience and German engineering.
However, we are far from getting on in years. Due to the continuous expansion and modernization of the interior and exterior of the buildings we can meet competitor’s demands more than just adequately and support our equipment with regular presentations at fairs and in close cooperation with our customers.
Of course, the outstanding “Black Forest made Quality Work” is designed by ourselves, and developed, and manufactured on high quality CNC machines.
To support us, we have access to a versatile program of machines:
For glass processing purposes:
Horizontal and vertical belt sanders
Single sided and double sided drilling machines
Sawing machinery
Shell handle grinders
Roller tables for flat glass handling
For metal processing purposes:
Horizontal and vertical belt sanders
Centreless cylindrical grinding and polishing machines
