K80 Combi Buckle/Knife Folding Machine


The K80 is MBO’s new combi folding machine for full size B1 and smaller sheet sizes.  With a blazing maximum machine speed, and wide range of fold pattern capabilities, it is well suited to the North American commercial print market and is ideal for high-precision, high-performance production of signatures, flyers and other general commercial products in industrial print environments.  Bolstering a 230 meter/minute (9,055 inches/minute) running speed, a common 25″ x 38″ sheet can be processed up to 13,755 sheets/hour; and smaller sheets even faster!  Even with conservative estimates, this represents a substantial increase in production rates over nearly any earlier vintage folding machine.  Ease of operation plays an important role in today’s market and the K80 is built with the operator in mind. MBO’s latest M1 controls platform uses a simple graphical interface with intuitive menu choices and complete integration.  Connectivity to the internet provides a way for MBO to gain remote access for service or software upgrades.  The K80 also utilizes a host of exclusive MBO design features like the slitter-shaft cassette for faster tooling changes, high speed knife folders in the second and third position, and servo controlled combi-plates eliminating manual adjustment and deflectors.  Easier processes, user friendly controls and automated functions, get jobs on and off the machine faster, translating to more uptime and maximum productivity. Even in today’s fast turn, short run market, the K80 is allowing today’s printer to think in terms of replacing vintage machines at a ratio of up to 2:1 or more while still reducing labor.
