ROTOCON Releases Digital Printed Label Converting And Finishing Machine


The next generation Ecoline RDF 330 uses the latest servo motor and software enhancements available. The shape of the machine has been modified by rounding off any sharp edges and introducing a sleek, modern colour palette of grey and red (changed from white and red) to give them a polished visual facelift.

The enhanced version, upgraded according to customers’ feedback, is now globally available. ‘The Ecoline RDF, initially introduced into South Africa back in 2013, has evolved into a globally supported brand with installations now across Australia, Europe and North America through ROTOCON Europe and ROTOCONTROL,’ said Michael Aengenvoort, CEO of ROTOCON.

‘By establishing close partnerships with our customers, we could incorporate their valuable upgrade recommendations to enhance the machine performance for offline label embellishments and finishing.’

A first major upgrade of the RDF 330 is an automatic sheer knife slitting system that simplifies the normally time-consuming set-up and tweaking required when manually adjusting blades across more than three lanes. The operator can now enter the label sizes, gap sizes, and number of slits, then the system will automatically bring all the blades into the right position with the correct gaps.

The second upgrade, which has been in big demand from customers requesting a more affordable and efficient format, is a high-speed matrix stripping system. It ensures no web in-between the stripping shaft and matrix, preventing waste breakage and machine downtime. Additionally, a servo-driven motor enables ideal stripping tension, even in the presence of matrix coil diameter variations. This avoids any issues caused by special substrates or die-cutting complex label shapes.

The third upgrade is a dual-turret slitter rewinder. It has two spindles that save converters time by allowing them to finish a roll of labels directly on the RDF 330 in one pass versus two passes as was done on the previous RDF model and a separate rewinder. This is especially useful for short-run work of 1 000 to 2 000 labels specified per roll in a run of 10,000, for example.

Inclusion of the easy-to-operate Ecoline branded UV LED curing system is a fourth important upgrade. It facilitates significantly lower operating costs thanks to energy savings, fewer consumable parts, and lower maintenance costs.
