ROVER RESEARCH SHOWCASES NEW WATER- JETTING TECHNOLOGY PRODUCT NEWS During the recent Futurmotive exhibi- tion in Bologna, Italian tech company Rover Research introduced an innova- tive new concept of retreading based on water jetting technology, which offers a radical change in approach to the con- cept of classical retreading. The Com- pany, initially created by Eng. Silvestro Mennella, has been supported by the Au- tonomous Province of Trento and subse- quently capitalised by the Truyoins Ven- tures fund. Enrico Fiore, the CEO of Truyoins Ven- tures, was present at the exhibition to ex- plain the new concept, which utilises so- called H2O demolition technology (water jetting) as an alternative method of buff- ing, which not only is claimed to save up to 50% in raw materials but also creates a premium devulcanised dust called Tyre- dust. This devulcanised powder has inno- vative physical-chemical characteristics, which, in addition to making it suitable for use in new compounds, also opens up new possibilities in the material recovery of the tyre. The new system allows water jetting to buff a thin compound layer to create the ideal surface for adding the new ma- terial. This system brings a real advantage in that it devulcanises the tyre surface, which means that the rubber molecule will open itself up and be ready to blend seamlessly with the casing. According to Rover Research, the new waterjet re- treaded tyres offer the same performance characteristics as new tyres. K738 NOW AVAILABLE IN 270MM WIDTH With the K738, KRAIBURG Austria found an optimal solution for two tasks last year: The in-house developed design is suitable for construction site use and, at the same time, shows excellent performance on the road. Following the new design’s success, Kraiburg has now made the design available in a further width. In addition to 250 and 260 mm, the K738 is now available in 270 mm – both in the K_base and K_plus compounds. According to Kraiburg, customers who already use the design on their trucks’ drive axle confirm that it stands up to the toughest off-road applications and proves its durability, traction and resistance in rough, unpaved terrain. At the same time, the smooth, quiet running characteristics on paved roads and the high mileage are claimed to be impressive. Large-design tread lugs are responsible for this performance and resist cracking and breaking as much as they increase tread durability. The K738 from the Upper Austrian retreading specialists is marked with M+S and 3PMSF symbols, making it suitable for year-round use. P.57
