Black Swan a New Marangoni Option for Smaller Scale Retreaders

For Marangoni Retreading Systems, the implementation of a high degree of automation into the retreading process is not the only innovative priority for its Ringtread retreading technology. The Italian based company also bills respect for the environment in compliance with European Commission CO2 emission reduction regulations as a factor worthy of top consideration. This approach to its business has led to the development of what Marangoni calls a new generation of machinery for applying cushion gum – the Black Swan.

Black Swan equipment is specifically designed for small to medium-sized tyre retreading firms that previously lacked a solution truly geared to their needs. The machinery applies the cushion gum automatically, thereby avoiding the use of adhesive solution and, in turn, the emission of solvents into the atmosphere. Further Black Swan functions include the filling of minor craters and even the reconstruction and reinforcing of the sidewalls. All of the above mentioned operations are part of a completely automated cycle that Marangoni says guarantees not only higher productivity, savings in labour, a reduction in processing times and reduced costs, but also environmental protection.

Cost savings occur courtesy of a number of factors, notes Marangoni: The elimination of adhesive solution during the application of the cushion gum cuts down the time required for this stage of the retreading process plus removes the need for specialised equipment. The Black Swan’s sidewall rebuilding/reinforcing function makes the application of strips of material upon tyre sidewalls unnecessary, leading to time savings. Thirdly, workforce numbers can be kept to a minimum as the operator working a building machine can also operate the Black Swan at the same time.

The main features of the machine are: three controlled axes, touch screen user interface, temperature regulation system, hydraulic chuck suitable for large measures up to those of the new-generation super wide single tyres, a completely automatic cycle, and compact construction. Thanks to the particular system that applies the cushion gum in strips, the machine also offers advantages over systems that apply the cushion gum simultaneously over the entire width of the tyre, namely the possibility of non-continuous work, flexibility in applying different thicknesses on various tyre cross-sections, and a saving of materials.

All of the above reasons, Marangoni concludes, are why the Black Swan is well suited for medium or small-sized retreaders who wish to limit variable retreading costs, anticipate compliance with increasingly strict environmental and safety regulations and improve the qualitative results of the retreading process.
