Muller Martini Launches New Saddle Stitcher


The three-knife trimmer of the new Primera Pro saddle stitcher is fully automated. Thanks to advanced Motion Control technology and servo drives, each of its format axes can be individually adjusted in case of any corrections – without compromise and without affecting other axes.

In addition, no brushes are needed for product guidance, only belts. These do not need to be adjusted, everything happens automatically. One of the highlights of the 14,000 cycle machine is its completely redesigned, variable-thickness three-knife trimmer, making manual intervention a thing of the past.

With the centre cut, the left and right (product) sections can be adjusted independently of each other. Any corrections can then be saved on the central control panel of the Primera Pro for interrupted or repetitive jobs and recalled in the same way at any time. Format and thickness settings – including asymmetries such as thickness, stops and cutting elements – are fully automated, as is product centring. The machine operators do not have to adjust anything by hand – not even the newly integrated full-format side centring for perfect head trim accuracy.

The targeted expansion of the Motion Control technology for the entire machine ensures a significant reduction in job set-up and throughput times and increases profitability thanks to the fast and error-free setup processes. To optimise the production process in the delivery, perfect quality is achieved – the first product can be sold right away. In addition, the independent decoupling of the gathering chain, stitcher and ejector systems opens up new application possibilities such as the flexible stitching head position for format changes. Together with its high format variability, the Primera Pro is therefore the ideal saddle stitcher for a wide range of products – for short runs as well as longer runs.

The completely redesigned, even more user-friendly operating concept, which includes intuitive operation with local control units and a large touch screen with redesigned visualisation, allows context-sensitive displays and standardised user guidance. The new interaction is therefore particularly easy to learn, which in turn reduces the need for training. This reduces costs and is also a great advantage when changing personnel.
