Stage 1

INITIAL INSPECTION

In the RINGTREAD production philosophy, operator expertise is irreplaceable and, along with specific operating machines, makes it possible to determine whether or not a casing can be retreaded.

The ITT inspection machines use the vacuum shearography technique to reproduce the image of the deformations at a microscopic level. By modifying the tyre's load conditions and overlapping images, the machine can detect "bubbles" that indicate separations.

This technique is much more precise, faster and more reliable than the methods used today: this makes it possible to create a retread with the best performances, safety and service life.

Stage 2

BUFFING

Buffing removes the residues of the worn tread and prepares the casing fo the application of the ring.

Our two state of the art Leonardo Rasp 2500 buffing machines allow us to generate the ideal buffing profile on each tyre.

Ensuring we have the correct buffing profile helps us maximise the tyres life on the road.

Stage 3

REPAIRING

Casing damage that occured during use is repaired before applying the ring.

Even for difficult repair jobs, the RINGTREAD system eliminates any defect from the rasped surface.

Stage 4

SUPERIOR QUALITY RETREAD

RINGTREAD is the only retreading system offering a circular, double-contoured and spliceless profile: the retreaded tyres manufactured using this technology are completely different from any others and are able to match or even exceed the performance and reliability of new high quality tyres.

Stage 5

CURING

Now ready, the tyre must be processed in an autoclave to allow the ring to bond perfectly with the casing, through the Marangoni Tread cushion gum that allows fast vulcanisation times.

Temperature and pressure values are studied to ensure optimum results without affecting the casing.

Stage 6

MONORAIL

The monorail handling system streamlines the production flow. In particular, it guarantees a perfect product that never touches the ground, from buffing to curing, thus without lowering the quality level.

A large number of tailor-made solutions are available to meet any and all requirements.
