Abstract
A tyre includes a body, a tread and an inner surface. Part of the inner surface has a noise-absorbing agent for absorbing tyre noise. The inner surface includes at least one spot free from noise-absorbing agent, provided with a module for wireless data transmission. The tyre includes a sensor arranged in the tread. The module is configured for reading data from the sensor. The module and the sensor are aligned to each other in the tyre. A method is for manufacturing such a tyre.
Claims11
A method for manufacturing a tyre, comprising:
- providing an unvulcanized tyre;
- vulcanizing the tyre,
- forming a blind hole for a sensor in the tyre before or during the vulcanizing the tyre, wherein the tyre comprises a tread, the blind hole for the sensor, and an inner surface,
- installing the sensor in the blind hole for the sensor,
- providing a noise-absorbing agent for absorbing tyre noise, on the inside of the vulcanized tyre so that:
- part of the inner surface comprises a location for a module, free from the noise-absorbing agent,
- attaching the module to the location for the module, wherein:
- the module comprises means for wireless data transmission,
- the module comprises means for reading data from the sensor inductively, and
- the sensor comprising means for inductive data transmissions to said module;
- the method comprising:
- detecting the blind hole for the sensor or the sensor, and aligning the location for the module by using location data obtained by the detection of the blind hole or the sensor so that a straight line which is parallel to a normal of the tread of the tyre at the location for the sensor passes through the location for the module and the location for the sensor, and/or a straight line which is parallel to the normal of the inner surface of the tyre at the location for the module passes through the location for the module and the location for the sensor, and
- after providing the noise-absorbing agent on the inside of the vulcanized tire, removing a portion of the noise-absorbing agent to form the location for the module, at which the inner surface of the tyre is free from the noise-absorbing agent.

A method for manufacturing a tyre, comprising:
- vulcanizing the tyre, wherein the tyre comprises a tread and an inner surface;
- providing a noise-absorbing agent for absorbing tyre noise, on an inside of the tyre so that part of the inner surface comprises a location for a module, free from the noise-absorbing agent;
- attaching the module to the location for the module;
- wherein:
- the module comprises means for wireless data transmission,
- the module comprises means for reading data from a sensor inductively;
- providing a blind hole for the sensor at a location for the sensor in the tread before, during, or after vulcanization;
- aligning the location for the sensor and the location for the module to each other so that a straight line which is parallel to a normal of the tread of the tyre at the location for the sensor passes through the location for the module and the location for the sensor, and/or a straight line which is parallel to the normal of the inner surface of the tyre at the location for the module passes through the location for the module and the location for the sensor;
- installing the sensor in said blind hole, the sensor comprising means for inductive data transmission to said module;
- attaching the module to the tyre by a double-sided tape by:
- attaching a first side of the double-sided tape to the location for the module on the inner surface of the tyre after vulcanization of the tyre;
- providing a second side of the double-sided tape with an adhesive and a release film covering said adhesive;
- providing the noise-absorbing agent on the inside of the tyre so that the noise-absorbing agent covers the double-sided tape;
- removing the noise-absorbing agent from an area defined by the double-sided tape by cutting an incision at a location of the double-sided tape in the noise-absorbing agent;
- removing the noise-absorbing agent from the area defined by the incision;
- and
- removing the release film from the double-sided tape.
