cushion gum and the tread using spindles, controlling the amount of rubber placed on each tyre by measuring the weight and the movements performed by the robot. The entire process is managed and monitored using
special prototype software that can generate profiles interactively.
The new technology applied brings significant improvements in the final products, both in terms of quality and performance, making them increasingly comparable to premium new tyres. The highly automated process also ensures greater flexibility and efficiency, reducing processing times and allowing more flexible management of production flows. Other upgrades are being made to the vulcanisation department, with the purchase of presses that can house 12 sector cylindrical moulds and that will further improve product uniformity by reducing the relatively frequent phenomena of ovalisation and unbalance when retreading a used tyre.
Massimo De Alessandri, Marangoni Spa CEO, stated “I’m more and more
convinced that there will be many opportunities for quality retreads in the future, and this is the focus of the efforts we are making to improve processes and increase efficiency at the Rovereto plant. The significant investments we have made, exploiting the day-to-day experiences at the factory and the innovations of our
Group companies operating in the mechanical sector, mean we can continue to perfect our technological development process and strengthen our cooperation with other players in the sector, for whom our company has always represented the reference partner in developing their projects in the retreading sector”.
Desser Acquires UK-Based Watts Aviation
Desser Tire & Rubber Co., LLC. Has announced that it has acquir ed
Europe’s leading aircraft tyre distr ibutor, Watts Aviation (“Watts”). Located in Gloucestershire, Engla nd, Watts distributes a broad ran ge of tyres and tubes for aviation as an authorised distributor for m ajor tyre brands.
Watts enhances Desser’s global fo otprint and further solidifies Dess er’s commitment to being a globa l leader in specialty aerospace dis tribution. Moreover, the combinat ion of Watts and Desser creates t he opportunity to enhance service
to its current customers via its br oadened, transatlantic footprint, a nd win new customers as a result
of its extended geographical reac h. The newly expanded company says it
will continue its focus on providi ng its customers exceptional level s of product support and service.
2015, features rotors with variable intermeshing clearance, and can produce compounds with extensive filler dispersion, a fundamental requirement for achieving treads with very high mileage and, at the same time, low rolling resistance. The new Banbury mixer will also improve the quality of earthmoving tread compounds, making them more competitive for heavy-duty applications.
Another important investment made in recent months concerns the building of hot-cure retreads in a production ‘island’ (see photo), in other words, a system that manages the entire tyre retreading process, fully automatically and flexibly. Constructed exclusively for the Rovereto plant, this production line features four extruders served by an industrial robot that applies the
