Abstract: In a process for building tyres for vehicle wheels, a carcass sleeve is arranged on a shaping drum including two half-drums and two supports. Each support is operatively associated with one of the half-drums and carries a plurality of turning-up levers having free ends positioned close to the respective half-drum. Two annular anchoring structures are disposed around the carcass sleeve and each of the two supports is locked to the respective half-drum by interposing only stiff mechanical elements in mutual contact between the support and the half-drum. The carcass sleeve is shaped in a toroidal conformation, by setting a threaded shaft in rotation and moving the half-drums close to each other. Subsequently, each of the two supports is unlocked from the respective half-drum and the threaded shaft is set in rotation to move each support close to the respective half-drum and lift up the free ends of the turning-up levers until the end flaps of the carcass sleeve are turned up around the annular anchoring structures.

Abstract: In building tyres, an intermediate portion of a carcass structure is built at a time on a respective forming drum within an intermediate forming line. The forming drum with the intermediate portion of the carcass structure is made available at a first transfer location. The intermediate portion of the carcass structure is completed through n completion locations with n≥1 and then transferred for the subsequent assembling with a crown structure to a second transfer location. At an operating moment in which the first transfer location is occupied by a forming drum coming from the intermediate forming line or intended for the intermediate forming line, from one to n locations selected from the n completion locations and the second transfer location are occupied by respective forming drums.

Abstract: A carcass sleeve including a carcass ply and a pair of annular anchoring structures is fitted around a toroidal forming drum arranged in a first radially contracted operational condition. The carcass sleeve is toroidally shaped against a radially inner surface of an annular contrast element. The forming drum is positioned inside the carcass sleeve and is concurrently expanded towards a second operational condition. Upon reaching the second operational condition, the toroidally shaped carcass sleeve is coupled to the forming drum. The forming drum, coupled to the carcass sleeve, is adapted to be transferred in proximity of an application device of additional components externally to the carcass sleeve.

Abstract: A process and apparatus for manufacturing tyres for vehicle wheels includes the step of building, on a forming support, a belt structure including at least one reinforcing structure of the so-called zero-degree type. The reinforcing structure is formed by depositing a continuous elongated reinforcing element on a deposition surface arranged in a radially outer position with respect to the forming support. The aforementioned deposition includes the step of exerting, through at least one element made from magnetic material, a magnetic attraction on a portion of the continuous elongated reinforcing element arranged at at least one pressing member and moving said at least one pressing member toward the forming support until the continuous elongated reinforcing element is brought into contact with the deposition surface.

Abstract: Within tyre manufacturing, a reinforcing structure of the tyre, such as the zero-degree layer of the belt structure, is made by an apparatus having devices for guiding a continuous elongated element towards a forming drum, devices for applying the elongated element against a laying surface of the drum, and a cutting unit to cut off the continuous elongated element when application has been completed. Once the cutting operation has been carried out, the free end of the continuous elongated element is set to a grip position downstream of the cutting unit, through a reciprocating slider and a threading element blocking the continuous elongated element with respect to the slider when the latter moves towards the forming drum.

Abstract: Method, process and plant for building tires for vehicle wheels wherein: in a service position of a carcass structure building line, a forming drum is associated with a pair of support elements including a first support element and a second support element; the forming drum is moved, associated with the pair of support elements, in a deposition line in the carcass structure building line; and the forming drum is transferred from the deposition line to a subsequent work station of the carcass structure building line. The transfer from the deposition line to the subsequent work station includes dissociating the forming drum from the second support element, keeping the forming drum associated with the first support element; transferring the forming drum, associated with the first support element and dissociated from the second support element, to the subsequent work station; dissociating, in the subsequent work station, the first support element from the forming drum, leaving the forming drum in the subsequent work station; and transferring the first support element, dissociated from the forming drum, into the service position.
