MBO K8RS

For B1 sheets (70 x 100 cm)

MBO K8RS

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.

Features in detail

Feeder head Vacujet RS in the palletized feeder
Standard feature
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.
Vivas (Double Vacubelt and Vacutable)
Standard feature
Vivas ensures reliable flat sheet infeed and optimum sheet run with high throughput capacity. It also guarantees no marks, even with delicate and freshly printed products. The new Double Vacubelt is equipped with four valves, which means increased suction power. The vacuum of the suction belt can be adjusted infinitely for the corresponding paper quality during ongoing production.
Maintenance and noise-free timing belt drive and belt drive
Standard feature
The tried and trusted MBO belt drive guarantees exceptionally quiet running and is virtually maintenance-free. Self-tensioning elements make testing and readjustment unnecessary. The functionality is monitored via the machine control. Low ongoing and operating costs make the MBO belt drive an exceptionally efficient long-term solution. The timing belt which drives the parallel fold of the K8RS guarantees slip-free running even at maximum speeds.
Vacuknife
Standard feature
The pneumatic drive allows a frequency of 40,000 cycles/h for the Vacuknife. The knife is led double-sided across the complete knife width and is driven linearly – therefore, the sheet is permanently led until it is delivered to the fold rollers and folded exactly at the specified spot. Moreover, the cross fold knife can be moved horizontally. Therefore, small formats with small sheet gaps can also be processed. The result: A higher output.
Cross fold sheet stop for ejection of waste paper
Standard feature
The sheet stop in the cross fold can be used as a waste paper ejector. Double or heavily misfolded sheets are ejected during production without interruption of the production flow. Immediately after the ejection the waste paper ejector closes again and the production is continued without any disturbance. Track-keeping tooth belts ensure optimal transportation of sheets.
Easily accessible cross fold and three fold areas
Standard feature
The cross fold area can be swung up and the three fold area can be extended. This allows free access to the fold-rollers and slitter shafts, facilitating setting and cleaning as well as the removal of paper.
