Abstract
An application system and method for applying a sealing agent to the inner surface of a pneumatic tire comprises: a support device operable for rotating the pneumatic tire around an axis of rotation; a dispensing head operable to be arranged inside the pneumatic tire in order to apply a layer of sealing agent to the inner surface of the pneumatic tire itself; a main extrusion device which is connected to the dispensing head and that is operable for supplying the dispensing head with a first throughput of sealing agent; and an additional extrusion device which is connected to the dispensing head, and which is separate and independent from the main extrusion device, and is operable for supplying the dispensing head itself with a second throughput of sealing agent that merges with the first throughput of sealing agent.
