Superfinish-aggregate or so-called pressure lamella belt aggregates are part of the high-end equipment. The chevron belt running between segmental pressure pad and sanding belt ensures a random interruption of the touch of the sanding grains. This produces a smooth sanding pattern which is free of oscillation marks. Anyone who produces workpieces made of lacquered MDF in the upmarket sector (high gloss, matt) cannot get around this unit.
Vacuum transport carpet and pressure pads
Lacquered and especially small, especially very short parts are only insufficiently held by the feeding belt. They slip under the units, jam or are thrown out of the machine. The vacuum transport carpet provides a remedy here. Pressure rollers and pressure pads between the units support the transport and prevent flat parts from "fluttering". They are available for sanding large and small workpieces.
Constant through-feed height
If you have particularly long workpieces to sand or want to integrate your machine into a line, you might want to choose a machine where the height adjustment is done by raising the machine head and the table maintains a constant height.
Roller brushing unit
Special roller brushing units fulfil many tasks:
Due to the high load, there are extra units for structuring and sanding brushes. Therefore, wide belt sanders are often equipped with two brush units.
