MORE TO ADD
The quest to add value to digital print translates into increasingly more sophisticated finishing and converting equipment being developed.
Finishing and/or converting, depending on your definition, are the processes that turn the printed sheets or reels into labels and packaging. Automation, quick changeovers, flexibility and adding value are the drivers behind the latest kit on the market.
Grafisk Maskinfabrik (GM) has a long history of developing finishing systems for the label industry. The Danish company was established in 1975 and remains in the hands of the same family. The company has seen demand for fully automated set ups rise and is committed to developing ‘Industry 4.0’ solutions, said CEO Uffe Nielsen, who also mentioned meeting the demands for ultra short run applications as a trend, along with Cloud connectivity and full integration.
For high-end drinks labels, the company has the DC330FB Combination finishing line, which at its heart has the DC330mini compact, with hot foiling, embossing and screen-printing added to create one workflow. "This line is ideal for short to medium run high-quality labels, particularly wine labels", explained Mr Nielsen.
The finishing line has been designed with a separate unwind on the compact section, so the machine can be used in full mode to produce high-end labels, or in basic mode, so that jobs which only require the flexo station, cold foiling and die-cutting can bypass the other features and run at higher speeds compared to feeding the whole line.
The DC330FB features a rotating foil tower on the hot stamping unit, which can accommodate two foils to run either along or across the web. This allows embossing and foiling to be done in one operation. Mr Nielsen explained, "This is quite important for designs where for instance you have both embossing and foiling on one label, but have a section where there is embossing, but no foiling."
The module has a pressure of 30 tonnes and the servo-drive system ensures equal pressure and impression time at all speeds. A built-in foil saver minimises running costs. It also features ‘slide-out’ plate loading which means plates can be changed while hot.
