Consistent automation from infeed to delivery enables extremely short job changeover times
The new Granit fully automated three-knife trimmer from Muller Martini uses SmartPress technology, resulting in consistent, first-class trim quality and can be used on a wide range of applications.
The trimmer uses patented SmartPress technology, to provide a 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 accurately. The SmartPress technology means that pressing automatically adjusts during production to fluctuations in product thickness, ensuring consistent book quality.
The trimmer 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.
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. The Granit also provides trim high quality in hardcover lines. 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.
