Method and system for removing a sealing agent from the surface of an inner cavity of an end-of-use pneumatic tire

Abstract

The invention relates to a method and a system for the processing of an end-of-use pneumatic tire that is provided with an inner lining layer manufactured with a sealing agent intended to seal any punctures and at least partially applied to the surface of an inner cavity of the end-of-use pneumatic tire. The system comprises an applicator device, which is provided with at least one nozzle suitable for dispensing a cryogenic fluid, preferably liquid nitrogen, upon the inner lining layer of sealing agent in such a way that the inner lining layer of sealing agent reaches the solid state; a device for the removal of the inner lining layer of solid sealing agent that is provided with a tool for removing the inner lining layer of solid sealing agent by means of mechanical abrasion; and a circuit for suctioning the solid sealing agent removed by the tool.
