MBO K8

For B1 sheets (70 x 100 cm)

MBO K8

The K8 combi folding machine stands for absolute precision and exemplary productivity. As a high-performance machine, it is designed for exceptionally high production speeds and production stability with minimum set-up times. With the K8, high performance, quality and flexibility go hand in hand, resulting in a folding machine which is ideal both for standard production runs and the creation of demanding and complex products.

As standard, the K8 comes with numerous high-end features, offering not only efficiency but also outstanding convenience of operation. For example, the intuitive M1 Advanced control and waste paper ejection through the cross fold sheet stop. Further configuration options, for example with regard to the range of folding types and level of automation, allow optimum adjustment of the machine to the production environment.

Features in detail

Feeder head Vaculift RS in the palletized feeder
Alternative feature
The Vaculift RS feeder head features exceptional ease of operation. It is based on mechanical lifting principles. The four bellows units of the Vaculift RS feature automatic height adjustment to the paper stack. This facilitates the set-up process. The Vaculift RS achieves a frequency of up to 25,000 cycles per hour.
Vivas (Vacubelt and Vacutable)
Standard feature
Vivas ensures reliable flat sheet infeed and optimum sheet run with high throughput capacity. The Vivas vacuum system replaces the standard suction wheel and the ball rails. Vivas also guarantees no marks, even with delicate and freshly printed products. The vacuum of the suction belt can be adjusted infinitely for the corresponding paper quality during ongoing production and saved.
Virotec fold rollers
Standard feature in parallel fold; alternative feature in cross fold / three-fold
The Virotec fold rollers are the MBO “all-rounders”. They consist of alternating metal and special PU segments that are offset against one another. Virotec fold rollers permit very good fold quality – even with challenging materials, such as recycled or thin printing papers, and at high folding speeds.
Slitter shaft cassette for single rear slitter shafts
Standard feature
The slitter shaft cassette is removable. At the ergonomically ideal height, all tools and strippers can be adjusted quickly and precisely, outside the machine. This means the operator does not have to lean inside the machine and can work in ergonomic comfort. The slitter shaft cassette therefore permits a one-person operation. It also contributes to a reduction in set-up time of up to 60 %, for example in multi-up production.
Vacuknife
Standard feature
The newly optimised 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. Novel track keeping tooth belts ensure optimal transportation of sheets.
