The head of the finishing line is usually the most appropriate position for the necessary sanding work. The most frequently used machine for wood sanding is currently the automatic cross and wide belt sander. The first unit sands in the cross direction, usually followed by two or, for high feed speeds, three or four wide belt sanding units, optionally using contact rollers or sanding pads.

After the sealer, the surface is sanded and prepared smoothly for the topcoat. The sanding process is carried out with wide belt units either using soft rubber coated contact rollers or electronically controlled sanding pads. For close-pore surfaces, the sealer sanding machine should preferably be equipped with two sanding units.

If workpieces are fed into the finishing unit already sanded, it is advisable to use this machine to ensure complete, pore-deep cleaning of the surfaces.

This machine is used for wood and lacquer sanding of profiled workpieces (max. profile depth 35 mm) and for lateral workpiece shaped edges.
