CSB stands for cutting, stripping, and blanking. The company says the Dymatrix XL 145 CSB comes in response to folding carton manufacturers’ need for appropriate die cutters to finish the sheets printed on their highly productive presses. Heidelberg adds that the new machine has a new optical feed system, a new pneumatic chase, and further preset modules which gears it maximum productivity and optimum precision.
The preset modules offer fine adjustment of the die-cutting plate position and format setting at the feeder. The chase changer and the quick-action clamping system for the stripping and blanking stations help ensure short makeready times during job changes. The company says that a completely redesigned main gear mechanism increases the speed to 9000 sheets per hour, adding that it has based the gearing on the technology used in presses, with no worm drives.
Heidelberg says its Prinect technology integrates the Dymatrix XL 145 CSB into the print shop workflow. It will make the Dymatrix XL 145 CSB available from midway through this year, augmenting the Dymatrix 145 CSB range.
The new machine supports weights between 80 and 2,000 gsm and processing materials 0.1 to 4 millimeters thick. Using the machine’s new Dyset XL feed system, each sheet is measured optically by three cameras, and the circumferential and lateral registers are then automatically aligned in the feeder. Sheets can be measured from the top and, optionally, from the bottom. Either the sheet edge, the printing mark or the print image is used for alignment purposes. Heidelberg says the benefits of this dynamic alignment include precision with a perfect die-cutting register of plus/minus 0.1 millimetres, fast makeready times, and a reduction in paper waste by preventing misaligned sheets.
Heidelberg adds that, thanks to a highly tolerant feeder inlet window, it is also possible to process less accurate piles. Narrow printing marks just 20 millimetres wide are sufficient. Like the colour and register marks for Prinect Inpress Control, these marks can also be integrated into the print control strip if necessary. The positions of the printing marks can be saved and called up as preset settings for a repeat job using the machine’s touchscreen. This enables motorised camera positioning. Remote maintenance is possible using Prinect Remote Service.
The machine has a new function for fine adjustment of the die-cutting plate and a compact chase changer speeds up the exchange of different cutting dies and extends the die cutter’s level of automation.
