Four Sword Brushes in all clean metal coils of steel, stainless steel, aluminium and non-ferrous metals from above and from below. The filaments of the brushes remove any contamination effectively from the surface. Lubricants remain on the metal strip and are spread evenly across the surface by the brushes.
The linear brushes are permanently refreshed in a self-cleaning unit to accommodate the continuous operation of manufacturing lines in industrial production. A rotating rack and compressed air nozzles detach particles mechanically and pneumatically from the linear brushes. The loose particles are then disposed of by means of vacuum extraction.
Each linear brush is flexibly bedded on a pressure buffer. The flexible pressure buffer provides for a consistent wiping pressure, even onto a wavy metal strip. Parallel guides prevent the linear brushes from tilting into the transport direction of the fastmoving strip. In this way, brush filaments always meet the surface at right angles and are therefore able to achieve premium cleaning results.
A pneumatic quick adjustment feature lifts the Sword Brushes instantaneously from the surface of the metal strip if a crash situation is detected. Transition areas or faulty sections at the beginning or end of a strip can pass through the Cevomat without damage occurring. The pneumatic stroke facilitates, in addition, a smooth coil changeover.
