Combi Folder 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.
MBO Solutions
Features
- MBO’s advanced M1 control system and graphic HMI for ease of use
- Extended pallet stack height to 120cm (47.2″) for additional paper supply for continuous run time
- Vivas (Double-Vacubelt and Vacutable) for constant sheet pull and best registration
- Ultrasonic double sheet control in the feeder/ alignment table for additional machine security
- Slitter shaft cassette in the parallel fold for fast makeready and kit style tooling changes
- Wide open knife folding area access at the crossfold for operator access at a moments notice
- 4 or 6 NIRO style non-corroding buckle plates in the parallel fold unit, first fold
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 extremely process-reliable and fast Vaculift 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).
