METHOD AND DEVICE FOR VULCANIZING TIRES
A method and a device for vulcanizing tires. The device and method allow a small width and an inexpensive construction of the device in particular by virtue of the special design of or the material flow produced by the device and method. The device has at least one vulcanization chamber and at least one unloader for unloading an at least partially vulcanized tire out of the vulcanization chamber. The device additionally has at least one depositing device, at least one sliding device, and a transport belt for transporting the tire away.
Method for manufacturing a patch equipped with a radiofrequency transponder
A process for manufacturing a rubber patch comprising a radiofrequency transponder, the patch having a first layer and a second layer, the method comprising moulding and vulcanizing a first layer, the exterior surface of which comprises a cavity able to receive a radiofrequency transponder, placing a transponder in the cavity, and then placing and vulcanizing a second layer in order to embed the transponder between the two layers.
Process for applying noise-reducing elements to a tyre for vehicle wheels
A process for applying noise-reducing elements to a tyre for vehicle wheels. A plurality of noise-reducing elements are arranged on a feeding belt movable along a predetermined feeding direction. The noise-reducing elements are subsequently aligned along the feeding direction and brought into mutual contact, to then be transferred onto a service plane arranged downstream of the feeding belt along the feeding direction and having, on an upper surface thereof, a continuous film which supports a layer of adhesive material. The layer of adhesive material is applied onto a lower surface of each of the noise-reducing elements taking it from the continuous film. The noise-reducing elements are then transferred one by one onto a conveyor belt arranged downstream of the service plane along the feeding direction. The noise-reducing elements are finally positioned one by one on a radially inner surface of a tyre.
Post-cure run-flat and/or noise reduction apparatus and method of manufacturing the same
A motor vehicle tire is disclosed with a pair of post-cure run-flat inserts, each of the pair of post-cure run-flat inserts is disposed within a tire cavity between a shoulder region and a respective upper sidewall region of the tire. The tire further includes a cylindrical sidewall defining an interior cylindrical cavity, each of the cylindrical sidewall and the interior cylindrical cavity extending 360 degrees about a rotational axis of the tire, the cylindrical sidewall having an exterior surface contacting a radially inner surface of an inner liner between the shoulder region and the respective upper sidewall region during a normal inflation condition of the tire.
PORTABLE TIRE SCANNERS AND RELATED METHODS AND SYSTEMS
Disclosed herein are devices and methods for determining the identity of markings on tires. A portable tire scanner can comprise one or more light sources and detector that reflect light off tire markings and capture imagery of them. The scanner is operable to process the imagery to determine the identity of the markings. The marking can be the same color as the area of the tire around the marking (e.g., black-on-black) and the scanner can identify the marking by determining angular edges of the markings. Plural light sources and/or detectors can be used to provide plural perspectives to better determine the edges of the markings. The housing can have a form factor that allows the scanner to be hand-held, such that a user can aim the scanner at tires even while on a vehicle or in hard to reach positions. The scanner can be used to scan and identify several tire marking in succession.
PROCESS AND PLANT FOR BUILDING TYRES FOR VEHICLE WHEELS
A plant for building tyres for vehicle wheels, includes a sleeve building area in which devices for obtaining carcass sleeves operate, a crown building area in which devices for obtaining crown structures operate and a shaping station for shaping each carcass sleeve according to a toroidal configuration. Transfer devices for transferring the carcass sleeves from the sleeve building area to the shaping station, by means of a first translator configured for picking up each carcass sleeve from an outlet station of the sleeve building area, a second translator configured for releasing each carcass sleeve in the shaping station, and a storage device operatively interposed between said first translator and second translator.
PROCESS AND APPARATUS FOR LOOPING ANCHORING ANNULAR STRUCTURES IN A PROCESS FOR BUILDING TYRES FOR VEHICLE WHEELS
An apparatus for looping anchoring annular structures of a tyre for vehicle wheels, includes at least three looping drums. Each looping drum has a longitudinal axis thereof, with respect to which it is radially expandable/contractible in a manner so as to turn up the loop around an anchoring annular structure. The apparatus also includes a loop deposit station, a loading station configured for loading the anchoring annular structures on the looping drum and an unloading station configured for unloading the looped anchoring annular structures from the looping drum. The loop deposit station, loading station and unloading station are angularly offset from each other. A turret transfer apparatus supports the looping drums in positions angularly offset with respect to each other and is configured for transferring the looping drums between the loop deposit station, the loading station and the unloading station rotating around a vertically-arranged transfer axis.
VALIDATION TOOL AND METHOD FOR VALIDATING OPTICAL EQUIPMENT
Provided is a validation tool and a method for validating optical equipment that is used for measuring a plurality of characteristics of one or more tyre components during winding application of said tyre components around a tyre building drum, wherein a first tyre component of the one or more tyre components includes a first characteristic of the plurality of characteristics which, after measuring, is overlapped by the same or another tyre component of the one or more tyre components including a second characteristic of the plurality of characteristics, wherein the validation tool is provided with a first reference element that is arranged to represent the first characteristic and a second reference element that is arranged to represent the second characteristic, wherein the second reference element is offset with respect to the first reference element to at least partially expose the first reference element.
Process for producing tyres capable of reducing cavity noise and set of tyres obtained thereby
The process for producing tyres comprises arranging no more than four sets of noise-reducing elements, each set being associated with a respective dimension L.sub.x different from each other; feeding in succession a set of tyres for vehicle wheels, having different values C of the inner circumferential extension; for each inner circumferential extension value, determining a respective number n.sub.x of noise-reducing elements for each set of noise-reducing elements, with x ranging from 1 to N, wherein for at least one value of the inner circumferential extension at least two respective numbers n.sub.x differ from 0; for each tyre, collecting from each set of noise-reducing elements the respective number n.sub.x of noise-reducing elements and applying the collected noise-reducing elements in circumferential sequence along an inner surface of the tyre, with dimension L.sub.x oriented circumferentially.
TIRE UNIFORMITY TESTING SYSTEM
A tire uniformity testing machine that includes a base, a pair of vertical spaced apart columns supporting an upper cross frame member. The base carries a load wheel carriage movable towards and away from a testing station. The vertical uprights establish a peripheral footprint plane that does not extend beyond a plane that is tangent to an outer rolling surface of the load wheel when it is redirected. The upper frame member includes clearance spaces and cutouts that enable at least a portion of an upper chuck to move into the upper frame member and a super structure mounted to a top of the cross member that mounts at least a portion of an actuator for translating the upper chuck. The configuration establishes a machine height that enables the machine to be loaded into a standard shipping container and reduces the overall footprint of the tire uniformity machine without compromising its ability to precisely sense tire uniformity parameters.
