Process<strong>in</strong>g<br />
<strong>The</strong> repair process <strong>in</strong>volves goug<strong>in</strong>g and hon<strong>in</strong>g out <strong>the</strong> damaged area with cutters and<br />
buffers. Often this <strong>in</strong>volves very f<strong>in</strong>e tool<strong>in</strong>g to cope with <strong>the</strong> high tensile steel belts. Once<br />
all separation is removed, a cushion, followed by a cap gum, is extruded <strong>in</strong>to <strong>the</strong> hole. If<br />
required, a re<strong>in</strong>forc<strong>in</strong>g patch is also added, and <strong>the</strong>n <strong>the</strong> area is re-vulcanised, us<strong>in</strong>g <strong>the</strong><br />
Monarch repair process, where heat and pressure are applied. <strong>The</strong> “cook<strong>in</strong>g” process can<br />
take up to 14 hours, depend<strong>in</strong>g upon <strong>the</strong> size and depth <strong>of</strong> <strong>the</strong> repair. After vulcanis<strong>in</strong>g,<br />
<strong>the</strong> tyre is shaped to match <strong>the</strong> orig<strong>in</strong>al tread pattern or shoulder pr<strong>of</strong>ile.<br />
Certified stands are used to support <strong>the</strong> tyres; some tyres can weigh up to 6 tonnes<br />
