Fully Automated and with a Wide Range of Applications 

The new Granit three-knife trimmer impresses with innovative SmartPress technology, resulting in consistent, first-class trim quality. The fully automated equipment has a wide range of applications in softcover and hardcover lines.

The Granit uses patented SmartPress technology, which has proven its worth in the higher performance range, to provide optimal, consistently high trim quality. It ensures a gentle and controlled pressing procedure in which all air between the sheets of paper completely escapes, even if the product is bulky, allowing for the product to be trimmed perfectly, which is key to consistently high product quality. SmartPress technology is adaptive. In other words, pressing automatically adjusts during production to fluctuations in product thickness, ensuring consistent book quality. 

Versatile Uses

The Granit three-knife trimmer from Muller Martini ensures cost-effective production in a wide range of applications. The Granit can take full advantage of seamless automation in a fully networked perfect binding line, such as the Pantera or Alegro A6. The operator can perform the necessary fine-tuning directly on the central screen of the perfect binder during production. In addition, the trimming cassette and pressing pad can be exchanged in just a few steps, which shortens job changeover times considerably.

Limited Investment Volume

If used in existing perfect binding lines, the Granit increases efficiency enormously. Production runs can be planned and performed efficiently with a job changeover time of just three minutes. The productivity of an older line can be vastly increased, especially for relatively small runs, while the required investment volume remains limited.

For Hardcover or as a Stand-Alone Machine

The Granit also provides top-class trim quality in hardcover lines. The SmartPress technology meets all the requirements in this area too. In order to achieve short setup times, the three-knife trimmer is easily connected to the commander of the casing-in machine, which enables size data to be transferred quickly. 

At companies where perfect-bound products are trimmed using a guillotine cutter, the production process is rendered considerably more efficient using the Granit. If the new three-knife trimmer is used as a stand-alone machine, loading is always ergonomic and safe.
