A method for manufacturing a tire (1) equipped with a communication module (20) consists in successively, and in the order required by the architecture of said tire, laying rubber products, notably profiled elements (50) and reinforcing elements on a given support in order to yield a green tire (1), then in vulcanizing the green tire to yield a tire (1), wherein, prior to laying one of the rubber profiled elements (50) on the green tire, a slot (52) is created starting from a surface of the rubber profiled element (50) and the communication module (20) is introduced into the slot (52).

A method and apparatus for detecting defects on tyres in a tyre production process. The method includes: receiving a reference image of a surface portion of a reference tyre substantially defects-free; providing a sample tyre to be analysed; illuminating a surface portion of the sample tyre with a raking light source; acquiring a sample image of the illuminated surface portion of the sample tyre; extracting the edges from the reference image and from the sample image and respectively generating an edge reference image and an edge sample image; carrying out a dilation of the edges of the edge reference image and generating therefrom a dilated edge reference image; comparing the edge sample image with respect to the dilated edge reference image and generating an edge image of possible defects; and identifying the edges in the edge image of possible defects.

A tire comprises an inner surface and/or outer surface with an accommodating region, an adhesive layer arranged on said accommodating region and a protective film arranged on said adhesive layer, characterized in that said adhesive layer is based on a block thermoplastic elastomer (TPE) comprising an elastomer block based on a diene elastomer comprising a molar content (or content by weight) of unsaturations of greater than 10%.

The invention presents a device and a method for placing and attaching a strip inside a tire. Specifically, the tire is positioned on a mounting in relation to a centering means, and an adhesive device is placed inside the tire. While the tire is rotated, the strip is moved inside the tire, wherein a pressure force is applied to said strip. The strip is driven at a linear speed greater than the rotation speed of the tire, thus producing an effect of compressing said strip, the length of which becomes less than the nominal length thereof, thus creating a space between both ends of the strip such that, after release, the strip scrapes the adhesive device, which is repositioned on said ends, thus simultaneously causing said ends to be attached end to end.

A method for segmenting the surface of a tire including at least one groove, includes: irradiating a portion of the surface of the tire by means of electromagnetic radiation having a wavelength in the visible spectrum; acquiring an image of the irradiated portion of the surface; and processing the image so as to segment it into regions corresponding to regions of the tire which do or do not belong to the at least one groove. Additionally, processing the image so as to segment it includes: calculating a statistical quantity associated with the irradiation by electromagnetic radiation for each region of the image; and determining whether the region of the image does or does not belong to the at least one groove according to the value of the statistical quantity. Equipment for segmenting a surface of a tire including at least one groove.

Method and plant for producing tyres for vehicle wheels in which: each vulcanizer (30) of a plurality of vulcanizers (30) is associated with a respective pick-up logic of green tyres from at least one storage area (20) of green tyres; upon each request to vulcanize a green tyre in a vulcanizer (30) of the plurality of vulcanizers (30), the pick-up logic associated with said vulcanizer (30) is applied to select and pick up a green tyre from the storage area (20); the respective pick-up logic associated with each vulcanizer (30) comprises a first pick-up rule of green tyres from the storage area (20) and, for at least one of the plurality of vulcanizers (30), the first pick-up rule is changed into at least one second pick-up rule at least once during the production in the plant (1) of at least one lot of tyres.

A method is provided for installing a mounting against a wall of a tire. The mounting is formed of an elastomeric material and holds an electronic module. The method includes steps of: providing a mould that includes a mould cavity, placing an unvulcanized mounting in the mould cavity, and vulcanizing the unvulcanized mounting simultaneously with vulcanizing other components of the tire.

An embodiment of the present invention provides an air injection valve-integrated spray for spraying and applying polyurethane foam to a desired portion of a tire. The spray includes a polyurethane foam chamber disposed at an end of a coupling portion and keeping polyurethane foam under pressure and an air delivery chamber delivering air injected from an air injection valve to a breaking portion of the polyurethane foam chamber, in which the breaking portion of the polyurethane foam chamber is broken by air coming out of the air delivery chamber, so the polyurethane foam is sprayed.

The invention discloses a tire building device and a tire building method. The tire building device includes a lateral-longitudinal-orthogonal 1 rail unit, a transferring ring, a carcass application unit, a bead placement unit, a belt application unit, a building unit, a shaping unit, and a tire unloading mechanism; the lateral and longitudinal orthogonal rail unit divides the tire building device into four areas, and also establishes the connection between the units through the transferring ring. The tire building method, including: 1) adhere the bead and tire carcass compound and then sent to the building unit; 2) send the belt compound to the building unit, 3) compound the carcass compound and belt compound into a carcass and sent to the shaping unit; 4) wind the carcass around the tread to form a green tire and sends it to the tire unloading mechanism for disassembly.

A method of mounting an object on a tire includes providing a tire having a sidewall, wherein the sidewall includes a mounting portion configured to receive an object. The method further includes mounting the object on the mounting portion of the sidewall, such that the object is visible without extending outwardly beyond the mounting portion.
