New three-knife trimmer Solit PRO: 
Making the Tried and Tested Even More Perfect

With its new Solit PRO three-knife trimmer, Muller Martini not only adopted the proven features of its predecessor model, such as SmartPress technology, but also surprised the market with a number of new features. 

It was exactly a decade ago that Muller Martini launched the Solit, the world's first three-knife trimmer in the medium performance segment with patented SmartPress technology. Thanks to this unique, servo-controlled technology, the air in the book block can escape optimally. Finally, the pressing force is automatically increased so that a perfect cut is made. Numerous printers and bookbinders on all continents appreciate the outstanding trim quality of the Solit, which can be changed over in less than three minutes without tools.

The new Muller Martini Solit PRO three-knife trimmer features a completely redesigned infeed with telescopic belt, take-off roller, feeder magazine, transfer flaps to the trimming table and servo-controlled, plunging infeed.

Now Muller Martini is launching the Solit PRO, the perfect technological three-knife trimmer further development. The proven features of the predecessor model have all been adopted – first and foremost the revolutionary SmartPress technology. In addition, the new 4,500-cycle three-knife trimmer with an infeed speed of up to 7,000 cycles per hour and a pile height of up to 85 millimeters impresses with a series of innovations that above all further improve the availability of the three-knife trimmer.

For example, the Solit PRO has a completely redesigned infeed with telescopic belt, separating roller, feeder magazine, transfer flaps to the cutting table, and servo-controlled, oscillating infeed pusher. The gate rollers provide precise infeed timing. The oscillating pusher allows easy feeding of new products. In addition, a unit has been developed which presses down the covers. This allows the gate roller to be moved to the exact thickness in real time.

As part of the redesign, the latest generation of motors and control components were also used and the complete lubrication system was optimized.

Thickness adjustment has been made faster so that changes can be responded to even better. As part of the design overhaul, the latest generation of motors and control components have also been used and the complete lubrication system has been optimized.

For softcover and hardcover
Thanks to the new cycle-accurate and reliable product infeed, the Solit PRO is even more process-reliable and optimally suited for use with both soft covers (for example, inline with the Alegro perfect binder) and hard covers (inline upstream of the Diamant MC bookline). The robust, one-piece cast construction of the new Solit PRO, which offers the largest format range in its performance class, ensures maximum rigidity. 

Other highlights include the shortest changeover times thanks to the high level of automation, tool-free job changes, and mark-free transport of the material to be cut. 

At the beginning of this year, the first machines of the new three-knife trimmer type were already delivered to customers – combined with very satisfied feedback.
