The fastest folding machine in the world

The K8RS is the frontrunner among the MBO combi folding machines. Based on the high-performance K8, the K8RS is trimmed for peak productivity. In addition, it features valuable, performance-optimising enhancements which not only allow the outstanding production speed of the folding machine but also guarantee the highest production quality and stability.
The K8RS shares all the advantages of the K8. The slitter shaft cassette, swinging up cross fold area and extendible three-fold area ensure ideal convenience of operation and extremely short set-up times. Wide-ranging automation options and a knife folding area which can be configured as required round off the possibilities offered by the K8RS. These features make the K8RS the perfect solution for the widely varying requirements of large and medium-sized print runs. With high-performance peripheral units such as the CoBo-Stack stacking robot, MBO also offers equipment for the entire delivery area after the folding process.

The RS makes the difference

The valuable upgrades which are provided as standard and increase productivity and production stability are what distinguish the K8RS. The palletized feeder of the K8RS can process pile heights of up to 130 cm (51 1/4”) – 10 cm (4”) more than the feeder of the K8 and K80. The sheets are separated from the paper stack by the newly developed Vacujet RS feeder head. The sheets are then transferred to the double vacubelt sheet  infeed system, which has two parallel suction belts and accelerates the sheets to production speed within a very short time. Heavy-duty timing belts and particularly powerful motors allow the K8RS to achieve speeds of up to 275 metres per minute (902 fpm).

Palletized feeder
The new palletized feeder is equipped with improved air routing, which means increased productivity. Thanks to the regulated, high-performance pressure vacuum pump, energy consumption is lower than that of previous models. The new pump also has a ventilated noise insulation device. The palletized feeder is suitable for processing pallets directly from the printing press. It is ideal for processing large runs with one-person operation.

The newly developed feeder head Vacujet RS offers exceptional ease of operation. It achieves a frequency of up to 25,000 cycles per hour. The Vacujet RS is also equipped with a new high-performance pressure-vacuum pump which regulates the air supply not continuously, but as required. This environmentally friendly solution consumes less than 50% of the energy compared to conventional pumps.


The K8RS is significantly upgraded with the CoBo-Stack collaborative stacking robot. The robot sets down folded signature stacks from the delivery onto the pallet. This relieves the operator of physical strain and allows him to take care of administrative tasks such as quality control or preparation for the next job. With the CoBo-Stack the performance of the folding machine can be utilised to the full and is no longer limited by the human factor. The CoBo-Stack is retrofittable to existing deliveries of type MBO A500, A700 and A80.

K8RS in comparison

In addition to the K8RS, the MBO range includes three further combi folding machines for the B1 / 70 x 100 cm format range: the K70, the K80 and the K8.

The K70 is the entry-level model from MBO. It is slightly slower than the other three models. The K70 is available as a manual machine and scores points with its very good price/performance ratio.
The K80 machine offers extreme ease of operation. It has a comprehensive standard configuration and several automation options. It is just as fast as the K8.
In comparison with the K80, the K8 has further integrated features which boost both the performance and convenience of operation of the machine.
