摘要： The present invention relates to a method and an apparatus for applying noise reducing elements to tyres for vehicle wheels. Noise reducing elements (12), all equal to each other, are fed in succession on a conveyor (20) according to a predetermined path and are oriented on the predetermined path all in the same way. Tyres (2) of different sizes (C, P) are fed in succession on a conveyor (20) up to an application station (34). In the application station (34), the noise reducing elements (12) are picked up from the conveyor (20) and applied to radially inner surfaces of the tyres (2). The application comprises: arranging the noise reducing elements (12) with the larger dimension (L) directed in a circumferential direction or arranging the noise reducing elements (12) with the larger dimension (L) directed in an axial direction as a function of the sizes (C, P) of the tyre (2) in which they are applied.

摘要： An apparatus for manufacturing tyres for vehicle wheels wherein each tyre includes a carcass structure formed starting from at least one carcass ply laid on a forming support extended along a longitudinal axis. The apparatus includes at least one device for positioning at least one annular anchoring structure on at least one end edge of the carcass ply, the positioning device being circumferentially extended around the longitudinal axis of the forming support and axially movable with respect to the forming support between an operating position distal from the forming support and at least one operating position close to the forming support. The apparatus further includes a device for turning up the end edge of the carcass ply around the annular anchoring structure, the turning up device being circumferentially extended about the longitudinal axis of the forming support and axially movable for approaching/moving away to/from the forming support. The positioning device and the turning up device are radially expandable/contractible in a synchronous manner with respect to the longitudinal axis of the forming support and are settable in a plurality of different operating radial positions, each operating radial position being selected based on a respective radial dimension of the tyre to be manufactured.

摘要： A process and apparatus for applying noise reducer elements to tyres. Each noise reducer element has an anchoring surface coated with an adhesive layer. The anchoring surface is illuminated with a reference radiation. The radiation emitted by the anchoring surface is detected; and a digital image representative of the anchoring surface is determined as a function of the emitted radiation. Each pixel of the digital image is associated with a respective brightness value representative of the amount of adhesive present in an area of the anchoring surface corresponding to such each pixel. One or more noise reducer elements are applied on the radially inner surface of a tyre.

摘要： Process and an apparatus for applying noise-reducing elements to a tyre for vehicle wheels that has a radially inner surface with a service area and having a circumferential dimension. The process determines the position in circumferential direction of the service area on the radially inner surface of the tyre, determines the position in circumferential direction of a target area on the radially inner surface of the tyre based on the position in circumferential direction of the service area, and applies a noise-reducing element at the target area. The position in circumferential direction of the service area is determined by circumferentially inspecting the radially inner surface of the tyre starting from a reference position, detecting the angular position of the service area with respect to the reference position and determining the position in circumferential direction of the service area based on the angular position and on the circumferential dimension of the radially inner surface of the tyre.
