Roba-Tech … sanding method The main idea of the Roba Tech principle is to avoid the main disadvantage of all today known rotational brush sanding machines: Those who work normally with sanding drum and a diameter of about 350 mm are only in a very small area in touch with the workpiece, about 40 mm. Only in the vertex of the radius of the tool a sanding process is possible. To compensate the very small sanding area normal sanding systems have to increase their rotation speed to a high degree. Only this way they have a chance to get nearly the same effectiveness. But this results a “hard touch” of the sanding paper which leads to an aggressive behavior on the edges, high temperatures and wavy optic of the material. Hurt edges and totally denibbed surfaces are often the result. The innovative and patented Roba Tech is equipped with a totally new developed sanding belt containing 174 sanding strips and provides a sanding area of approx. 1300 x 1600 mm in touch with the workpiece and more than 250 meters of sanding material on all aggregates. This is unique on the market of brush sanding machines. A 360 ° rotation of the sanding aggregate makes it possible to reach all edges and corners of a work piece. Due to the by this means enlarged sanding effectiveness the machine is able to get best cutting

The advantages of the Roba Tech principle summarized:

1. Large abrasives quantities make low movement speeds possible, at better effectiveness.

2. The rotational sanding head with a large

sanding area ensures a consistent sanding in all work piece areas.

3. Free PLC programmable sanding parameter to optimize results.

4. A perfected vacuum system guarantees that even drawers can be feeded surely.

5. A "pulling" sanding avoids wavy surfaces and penetrates deeply into the milled grooves.

6. The low rotational speed guarantees long abrasive lifespan because the sanding segments do not hit the work piece edges that hard.

7. Abrasive configuration is freely eligible from the MB-Flex system.

The Roba-Tech has three programmable sanding options: Rotation-, Oscillation- and belt

Hurt edges and totally denibbed surfaces are often the result. The innovative Roba-Big is equipped with a totally new developed sanding wheel with a diameter of approx. 630 mm which it makes possible to obtain a larger sanding area (about 300 mm) in touch with the work piece and more than 500 meters of sanding material on each aggregate. This is unique on the market of brush sanding machines. Due to the by this means enlarged sanding effectiveness the machine is able to get best cutting results by lowest rotation speeds. As a result of this, low movement speeds let the sanding strips slide gently into the milled grooves and sand them every effective. The Roba-Big is equipped with two rotational heads, One is clockwise sanding, followed immediately by counter clockwise sanding.

Only in this way it is ensured that, independently of the wood grain structure, all upstanding „hairs“ are denibbed. Many by PLC adjustable sanding options help the operator to set the machine to his special sanding requirements.

The Roba-Anti Dust as through feed solution guarantees high productivity with best cleaning results. Solution as stand alone version or for large amounts or directly before the lacquering line. Many users have the problem of imbedded dirt and dust particles after lacquer application. These particles are not removable anymore, because they are placed under the lacquer layer. Ordinary machines with a cleaning brushes transverse to feed direction solve the cleaning problem only insufficient because they are only able to remove dust from the grooves in feed direction, leaving dust in the crosswise grooves. Even worse they sweep all dust into these grooves. The new MB system solves the problem with the help of an oscillating cross unit. This unit takes care that the whole part is cleaned completely, even in the complicated contours. Special brushes collect the dust, ionization brushes reduce static loads, and a blower system finish the cleaning process. On demand the machine is deliverable with a bottom cleaning unit.

Only this way they have a chance to get the needed effectiveness. But this results a “hard touch” of the sanding paper which leads to an aggressive behavior on the edges, high temperatures and wavy optic of the material. Hurt edges and totally denibbed surfaces are often the result. The innovative and patented Roba Belt is equipped with a totally new developed sanding belt containing 138 sanding strips and provides a sanding area of approx. 700 x 300 mm in touch with the work piece and more than 70 meters of sanding material on the aggregates. This is unique in the market of brush sanding machines for profiled mouldings. The Roba-Belt machine in all its configurations is build for sanding mouldings found in various furniture, window and joinery companies. Solid, veneered or lacquered. Especially in the flooring industry this machine is often used, due to the very high feed speeds necessary. Due to the modular construction of the Roba-Belt line, the machine can be configured to every customer demand, even for a four sided sanding

layout. In the main configuration the Roba-Belt achine contains one RB300 sanding head and a pressure roll system. Configurated in this way it is a solid basic layout for those customers who wish an optimized price-performance ratio. Equipped with the MB Flex brush system the machine is very easy and fast maintained and set up for a new profile.

Roba-Simplex Roba-Duplex … sanding method The Roba Simplex/Duplex consists of one or two sanding areas of 100 mm. The height adjustment is done pneumatically in fast movement mode. In this machine two different sanding paper settings can be used. For example for rough wood sanding a grid 120 is placed in the upper belt, while in the lower belt contains a grid 180 for the fine finishing. The change of the sanding areas is done by pneumatically enforced movement with the use of a manual switch. That means that no pre settings are needed. 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.

Roba-Flat … operation areas The Roba-Flat was developed especially for the window manufacturers who do individual single piece production. However, it also finds possible implementations in all joiners’ workshops and industrial plants. Operation areas:

* intermediate lacquer sanding * wood fine sanding

The Roba-Flat machine stands out due to the simple operation and optimal denibbing results. The time for processing is shortened considerably. The flat parts of the work piece are sanded in area 1 with the short sanding paper setting. This area is 150 mm wide. The shaped profile parts are sanded in area 2 since the slim slotted paper is able to get into the depths of the profiling easily. This area is 100 mm wide. In this way the four-sided denibbing process lasts only a few seconds and does not strain the employee due to the ergonomically favourable construction of the "lying" dragging aggregate. The new constructed Twin Flat contains two brush belts which movement direction is outward orientated. This avoids a too aggressive rounding of the edges and burn through during sealer sanding procedures. Another advantage is the improved handling of long work pieces.

LA-500 … gluing operation

The two part gluing tool has up to three main channels connected with a valve block. In this way every

channel can be provided with the needed glue separately. So every kind of gluing can be done specifically and independently.

In the five piece door production in the furniture industry the operator has the possibility to define exactly where he wants glue to be squeezed out and where to avoid it.

The valve block has three separately adjustable control valves

Cleaning is done weekly and only takes about 10 minutes. For this reason every valve block is equipped with a glue supply and a

water cleaning connection.

2. Separately adjustable valves

3. Two pieces glued in one process (operation time about 3 sec.)

4. Weekly cleaning efforts about 10 minutes.

5. Save processes, even after years

6. Easy to replace tools for different profile layout – recommended by our customers

MB-Flex … operation areas

The sanding brush system is used for wood fine sanding, lacquer sanding and polishing of oil and wax applications. The sanding brush consists of a core which is able to take the sanding segments in its keyways. The core itself is not a subject of wear and can be set up for new configuration.


Top-sanding quality for lowest costs possible!

Core bore to customer requirements

Core diameter 110 mm/24 segments



Core types MB-Flex

Core length can be produced according customer requirements

Due to the pluggable brush system, different sanding segments can be mixed with different abrasive slottings. With this possibility the customer can produce a sanding brush which is suitable for a large work spectrum and different requirements.

Help for the right adjustment of the segment slotting slotting:

Slotting S (mm): 0, 4, 5, 7, 10, 15, 20, 25, 35, 50, 100 Grid recommendations: Sanding of hardwood: K80 - K150 Sanding of soft wood: K150 - K220 Lacquer sanding: K180 - K400 Sanding paper recommendation: Aluminum oxide: for wood fine and lacquer sanding Silicon carbide: for lacquer sanding Brush backing recommendation: Standard: for soft & hard wood sanding Super Flex: for soft wood and lacquer sanding

Slotting options: Which slotting is chosen depends on the profile layout. If a work piece with a milled groove of 8 mm has to be sanded, the slotting has to be smaller (5mm). Flat work pieces should be sanded with a slotting of 20 mm or wider. If an edge is damaged in the process of lacquer sanding of flat pieces, the slotting width has to be reduced. An other variation of the MB Flex system is the "Super Flex" support brush. This is always recommended if scratches in the work piece surfaces or white lined edges during sealer sanding operations have to be avoided Especially in the field of lacquer sanding this system shows very good results. Because the MB Flex system is also used in machines of other suppliers, MB offers dove tails in different sizes. In this way the customer can be sure that the delivered strip fits into his machine.

If companies want to sand all kind of mouldings in an uncomplicated and fast way, they have to consider the moulding sanders from MB Maschinenbau. One totally new development is a

combination of the Roba Belt and Roba Profile machine line: the Belt aggregates equipped with low grits do the basic sanding and the double brush units with higher grits are responsible for finish sanding. Due to the roller transport system the machine is able to sand even narrow profiles. Setup for a new profile can be done in a few minutes.

The effective working and easy to maintain MB surface sanding machine are favoured by many worldwide customers. But in some cases there is also the need for an additional edge sanding. Now, with the new developed side sanding aggregate, there is the possibility to integrate such a device in every line. Equipped to customer demands this new unit can be added to all MB surface sanding machines. Up to five vertical sanding units are movable sideways via spindle support. The position is free selectable and in case the aggregates can be moved outside the working area.
