The Roba Simplex/Duplex
consists of one or two sanding areas of 100 mm.
The height adjustment is done pneumatically in fast movement mode.
The system is based on a sanding belt system instead of rotating brushes. The advantages compared to rotating brushes are obvious:
The work pieces must only be pressed against the sanding belt and not, compared to a normal brush system, be moved from right to left
through the brush. This results in considerable lower processing time.
