Spanish flexible packaging producer Emsur Saymopack has increased its productivity and the lifetime of its sleeve adapters with the new rotec Eco Xtra ring from Xsys. The next-generation Eco Bridge technology further improved the durability of adapters by reducing wear from mounting sleeves.
The Eco Bridge adapter is a patented technology that enables significantly easier sleeve mounting, as well as more efficient compressed air usage. The next generation maintains these advantages while taking sustainability to the next level. The Eco Xtra is a modified stainless-steel ring that incorporates the air supply system of the Eco Bridge and additionally guards against wear by strengthening the operator-side of the adapter.
The first customer to take advantage of this innovation is Emsur in Spain, which has been testing the Eco Xtra adapter at its Saymopack plant, in Valencia.
‘During rough production processes, our adapters were becoming damaged quickly, so we needed to reinforce the operator side. The new ring with the innovative air supply protects the adapter from wear and improves the mounting characteristics quite significantly, as well as the overall lifetime,’ said Marcos Gaspar Calatayud, responsible for process improvement at Emsur Saymopack.
Through the Xsys regional agent, LR Flexo, Emsur Saymopack has enjoyed the benefits of rotec sleeves and adapters for plate-mounting on its wide web flexo presses for more than ten years.
‘We have had a great relationship with LR Flexo for many years, and we always get the best service,’ added Calatayud. ‘And now, with the new Eco Xtra ring, they even developed something designed specifically for our needs. We can now mount our sleeves much faster and speed up the whole process.’
To further improve on the performance, the Eco Xtra Adapter has incorporated the original Eco Bridge technology and its advantages into a new steel ring, making it more robust.
‘All adapters, including the Eco Bridge, will wear over time, as sleeves are mounted and demounted, hitting the edge of the adapter day in, day out,’ commented Uwe Mueller, product development manager for XSYS. ‘This wear will cause the compressed air to start leaking, which will increase the time needed for mounting and eventually render it impossible. The new Eco Xtra ring prevents this type of wear while still ensuring fast and perfect mounting every time.’
‘Although it sounds like a simple solution, these new carriers with the “metal ring at the end” are a remarkable improvement that makes the mounting of printing sleeves fast and simple. Even more remarkable is that it extends the useful life of the adapter itself. We would like to add this technology to all the adapters we use on our presses,’ commented Calatayud.
