The new double unwinder on an XFlex X4
Omet’s open house event in May saw the unveiling of two new additions to the company’s product portfolio, a double unwinding system and the flatbed hot foil unit from Pantec.
The unwinder is aimed at reducing waste during job changeovers and to save time. The operator can switch from one material roll to another previously uploaded on the second shaft of the double unwinder, cut, splice and start printing.
The second unwinding shaft is an option that can be applied to the printing presses of the XFlex line. The two shafts can be used alternatively so the preparation of the new roll on the free shaft could be done while the machine is still in operation.
Overall costs are reduced by 75% and machine downtime to less than one minute versus three minutes on a configuration without double unwinder where extra time is needed to remove the core of the finished roll and upload the new one.
The Rhino flatbed hot foil unit from Pantec can be integrating inline on the XFlex X6. It can achieve high relief depths thanks to its longer retention time in comparison to the rotating process; adjustable, accurate processing time independent of the production speed, as well as a robust design and delivers uniform embossing pressure under extreme conditions.
The unit can be used with low cost flatbed foil on rotary presses and flat embossing tools, making savings in material costs. In addition, a special foil saving system reduces the overall material supply. It does not impact on the speed of changeover using one-pass technology, as the embossing systems change is minimised with a special tool cassette system.
