METHOD AND SYSTEM FOR APPLYING A SEALING AGENT TO THE SURFACE OF AN INTERNAL CAVITY OF A PNEUMATIC TYRE

A system is provided for applying a sealing agent to an surface of an internal cavity of a pneumatic tire. The system provides for detecting the weight of the pneumatic tire before and after the application of the sealing agent to the surface, calculating the difference between the quantity of sealing agent applied to the surface and a reference quantity of sealing agent; storing the difference within a short-term memory buffer and a long-term memory buffer; determining a short-term compensation factor and a long-term compensation factor and calculating a correction factor using alternatively the short-term compensation factor or else the long-term compensation factor; and using the correction factor to actuate an applicator device during the subsequent step of applying the strip of sealing agent to the surface.
