In the past few years, many customers have tried to deal efficiently with the ever smaller print runs by using a digital printing machine. This is a useful first step: it replaces an analogue with a digital process. Set-up times, start-up waste, tool procurement, storage and recycling are further issues that can and must be addressed. ALS Engineering considers the whole digital value-adding process, starting with the end product and ending with the production of the label form in the pre-press stage.
The final conversion to the right roll core widths for differing orders on large rolls often presents challenges. SmartCore (width 330-500mm) is an automatic roll core cutter which receives the cutting information from the order system, e.g. from a laser die-cutter. Wrong cores become a thing of the past.
With a semi-automatic rewinder on the laser die-cutter, the operator can dispense adhesive onto cores after automatic cutting, apply a two-sided adhesive tape, then place the lengths cutting web on the core spindle in around 5 seconds and proceed to the next order.
Automatic adjustment of the slitter knives enables you to change orders in seconds, with no manual intervention, using barcode control in combination with the laser die cutter and digital printing system. The laser die cutter runs continuously thanks to the upstream material buffer. Up to 700 different orders a day can be processed and delivered.
A variable material buffer with max. 30 metres of storage volume provides for continuous production of self-adhesive labels.
