Application System and Method for Applying a Sealing Agent to the Inner Surface of a Pneumatic Tire

A system for applying a sealing agent to the inner surface of a pneumatic tire, the system comprising:

• a support device configured to rotate the pneumatic tire around an axis of rotation;
• a dispensing head configured for being arranged inside the pneumatic tire to apply a layer of sealing agent to an inner surface of the pneumatic tire;
• a main extrusion device connected to the dispensing head and configured to supply the dispensing head with a first throughput of sealing agent;
• and
• an additional extrusion device connected to the dispensing head, wherein the additional extrusion device is separate and independent from the main extrusion device and is configured to supply the dispensing head with a second throughput of sealing agent that merges with the first throughput of sealing agent.

A method for applying a sealing agent to the inner surface of a pneumatic tire, the method comprising:

• rotating, via a support device, the pneumatic tire around an axis of rotation;
• applying a layer of sealing agent to the inner surface of the pneumatic tire via a dispensing head arranged within the pneumatic tire;
• supplying the dispensing head, via a main extrusion device, with a first throughput of sealing agent;
• and
• supplying the dispensing head, via an additional extrusion device that is separate and independent from the main extrusion device, with a second throughput of sealing agent that merges with the first throughput of sealing agent.
