MBO Group is currently the last supplier of large-format folding machines. Demand for these machines has fallen significantly in recent years. On the one hand, this is due to the drop in the length of print runs. In addition, many printshops/bookbinding companies print in medium or small format anyway, or halve the printed large-format runs before carrying out the finishing process.
However, some companies deliberately opt not to separate the sheets before folding. This is mainly for reasons of quality. It is almost impossible to cut large-format sheets cleanly without a loss in quality. Tolerances which arise during the cutting process inevitably also affect folding. This is an absolute no-go if you want to produce high-quality books! Maps and posters are other examples of large-format applications.
MBO Group are the last manufacturers of large format folder in the T1120P and the T1420P
MBO has two buckle fold machines for large sheet sizes in its portfolio. The T1120P can process sheet sizes of up to 112 cm x 165 cm and the T1420P which processes sheet sizes of up to 142 cm x 205 cm. The M7 from Herzog+Heymann can process even larger formats with a maximum print sheet width of 165 cm. When it comes to length, the M7 can process sheets of 200 cm and more. Herzog+Heymann is part of MBO Group and specialises in custom machine engineering.
At the MBO Group headquarters in Oppenweiler, work is currently underway on two T1420P machines for an Italian customer. Further inquiries, including another one from Italy and one from Spain, are also being processed. Italy and Spain are countries where large sheet formats are typically used. However, there are also several large-format machines from MBO in operation in the Czech Republic, France, Germany and other countries. The UK Hydrographic Office (UKHO) have previously ordered two specifically for maps.
The T1420P is supplied with a MABEG palletized feeder as standard. The long register table with two sidelays ensures reliable alignment of large, long sheets. Vacuum belts transport the sheets without marking them. The combination with a lattice-type table ensures that no static charge is generated.
Because of its size the buckle plates of the T1420P are very heavy. This makes it particularly convenient that the buckle plates can be lifted out pneumatically for adjustment of the sheet deflector. In addition, all adjusting elements for the buckle plates are located on one side. As there is no need for the operator to go around to the other side of the machine, it can be operated by one person working alone. The optional, patented sheet return device (RFE) also makes for added convenience of operation. It reduces the path between feeder and delivery by around 80%. Further advantages of the sheet return device are higher effective output and a significant space saving.
The standard equipment of the T1420P includes many other tried and trusted MBO features, for example the low-maintenance belt drive, the ergonomic, patented slitter shaft cassette and the waste sheet deflector. Double sheets and incorrectly folded sheets are detected by means of ultrasonic sensors and sheet monitoring and ejected after the first folding unit without interrupting production.

So, although the requirement has reduced, customers who need the quality and the specific sizes for large format can still be given a high-quality solution from the best manufacturer of folders in the world.
