Dutch machine maker VMI launched its new Unixx belt maker, which it says produces “high quality endless steel belts by means of an innovative and accurately controlled extrusion process that can handle a wide range of compounds”, at the Tire Technology Expo 2023, held in Hannover, Germany, recently.
The system is optimally suited for hands-off, eyes-off production. Scrap and waste from angle- and compound changes are reduced because of the limited width of the extruded strip. Next to this, the automated and accurately controlled process produces a consistent high quality belt.
The extrusion and cutting process, reduced waste and scrap, lower energy consumption and minimum operator involvement, result in a lower overall cost per produced square meter steel belt compared to the conventional belt making process, according to VMI.
The belt maker also allows for the production of thinner belts to reduce tire weight and rolling resistance without compromising tire performance, contributing to a lower fuel consumption and CO2 emission levels.
The new machine is part of the VMI Unixx technology platform, a development programme for integrated tyre building that will add value to existing process by simplifying, reducing energy resources and energy use and improving quality, claims VMI.
“Allowing our customers to become more flexible, be able to build even more specialised tyres and to make the tyre building industry future fit,” it says further.
