DAVI revolutionizes the plate roll market, introducing the Planetary Guiding of the side rolls, that are: friction-free, mill-scale-proof, lubrication-less and maintenance-free. They improve the machine accuracy and extend its life. These Planetary Swing Guides produce a much shorter flat-end during pre-bending and the tightest diameter cylinders, slightly larger than the machine’s top roll diameter. Planetary Guide is PATENTED by DAVI.
