Designs and accessories

Using Koellmann gears that have been customised to the individual requirements, extrusion system manufacturers can cover all of their gear needs. These gears combine the highest possible standardisation with compact, one-piece universal housing with maximum flexibility in terms of designs, connections and accessories. The gears can be used in all installation positions, and can even operate at an angle, thus, for example, as a co-extruder. The gears can even be used lying on their “bellies”.
