Contact roller unit with rubber contact roller (85 shore) for calibration work, Electro-pneumatic sanding shoe for fine work and veneer work, The combination module with electro-pneumatic sanding pad is used mainly to machine solid wood and for veneer work, Upon initiation of the sanding process, the electro-pneumatic sanding pad is lowered 1/10 mm onto the workpiece. This avoids the risk of penetrating the veneer at the front and rear of the workpiece. The guidance system is steered by a distance trigger and impulse counter system. The pulse counter regulates the movement of the sanding pad depending on the feed rate

Contact roller unit with rubber contact roller (85 shore) for calibration work, The combination module with segmented, electro-pneumatic sanding pad is particularly useful when working with veneered surfaces of varying depths or shapes,
Individual segments can be deactivated and reactivated. You can hereby ensure that the machine only sands the scanned width of the workpiece

The belt guidance system scans the workpiece using a modular spotlight and activates the electro-pneumatic belt guidance system, which moves the belt fowards and backwards. In addition, safety switches monitor the sanding belt speed. If there is a risk that the sanding belt runs off course, the belt speed control stops the sanding belt motor immediately.

Your Format-4 wide belt sanding machine is equipped with a continuously variable feed rate of 4–17 m/min. Depending on the type of wood, the grit size or the sanding belt condition, the depth of cut decreases if the feed rate increases.

A vacuum table is available as an option for very smooth, small and thin work-pieces. The vacuum is created by a high pressure air blower coupled to the feed table. When the blower operates, a vacuum is created in the cavities of the feed table. This vacuum then acts on the workpiece through the holes in the vacuum feed mat.

With this option, the contact rollers can be engaged or released via the control panel. In combination with the storable programs, the flexible operational application of the machine is made even easier.

The blow-off facility is necessary when grinding lacquered workpieces. It cleans the sanding belt exceedingly well and this as a result, prolongs the lifespan of the sanding belt.

The automatic thickness measurement function facilitates the desired workpiece thickness machine setting. No additional gauges are required to measure the workpiece thickness as it can be measured directly on the machine. The desired depth of cut can be pre-selected on the adjusting handwheel; + and – settings are possible.

As an option, on the delivery side of the machine, it is possible to set up a brushing facility. Different brushes can be inserted and their task is to clean, polish or structure the workpiece surface.

The infinitely variable (sanding) belt speed is required specifically to sand lacquered surfaces. This detail increases the operational use of your wide belt sanding machine. The sanding belt speed can be adjusted continuously from 2.4 to 19 m/min.

Two control panels are available. Via the standard control panel, the individual units are manually selected and activated via a switch. The controlled variant with segmented sanding pad offers 200 program storage spaces. The unit to be activated depends on the pre-selected program.

If required, we are able to equip your Format-4 wide belt sander with roller extention tables both on the infeed and outfeed side.
