Method of retreading a tire having a detectable carcass cushion layer

This invention relates to a retreadable tire (1) which contains a non-black colored rubber carcass cushion layer (4A) sandwiched between its tire tread (2A) and tire casing (3). The non-black colored rubber carcass cushion layer acts both as an adhesive and transition layer for adhering a cured or u...

Beschreibung
Zusammenfassung:	This invention relates to a retreadable tire (1) which contains a non-black colored rubber carcass cushion layer (4A) sandwiched between its tire tread (2A) and tire casing (3). The non-black colored rubber carcass cushion layer acts both as an adhesive and transition layer for adhering a cured or uncured tire tread to the cured tire carcass. Such carcass cushion layer also acts as a detectable color indictor for indexing and monitoring a complete removal (e.g. by buffing, abrading, or cutting) of the circumferential rubber tire tread and partial removal of the carcass cushion layer without removing the entire carcass cushion layer. The invention also relates to a method of retreading a cured rubber tire carcass by completely removing a circumferential, carbon black reinforced (and therefor a black colored) tire rubber tread together with a partial removal of the contrastingly colored cured rubber carcass cushion layer to a depth indexed and/or determined by an automated rubber cushion layer color sensing means (8), or apparatus, followed by applying a non-black colored uncured circumferential rubber carcass cushion layer (4) and carbon black reinforced (therefore black colored) tire tread (2) thereon to form an assembly thereof and vulcanizing the assembly in a mold to form a retread tire (1).
