Abstract: A plant (1) for looping annular anchoring structures (100) includes a looping device (2), a separation station (8a) and a coupling station (8b). A handling apparatus (3) is interlocked to the looping device (2) for managing the plant (1) by moving the plurality of annular anchoring structures (100) coupled to respective separation elements (300), the looped annular anchoring structures (200) coupled to respective separation elements (300) and the separation elements (300a). The separation elements (300) are fed, coupled to respective annular anchoring structures (100), along a feeding section (A1). The separation elements (300a) separated by respective annular anchoring structures (100, 200) are transferred from the separation station (8a) to the coupling station (8b) along a transfer section (T), stationing in at least a first intermediate station (11, 11a). The separation elements (300) are moved away, coupled to respective looped annular anchoring structures (200), along a moving-apart section (A2).

Abstract: A process and a drum for looping annular anchoring structures in a process for building tyres for vehicle wheels includes: depositing a loop on a drum including a radially expandable/contractible intermediate annular portion and, in a position axially adjacent to the opposite axial ends of the intermediate annular portion, a pair of radially expandable/contractible lateral annular portions; associating an annular anchoring structure with a radially outer annular surface portion of the loop defined at the intermediate annular portion; and turning up each of opposite end edges of the loop on the annular anchoring structure through the lateral annular portions as a result of a thrusting stress imparted by a respective lateral annular portion of the pair of lateral annular portions because of a synchronous radial movement and a synchronous axial displacement of a respective plurality of circumferentially adjacent first angular sectors.

Abstract: A station for checking tyres includes a support structure defining an operating space for receiving a tyre and an overturning device with grip elements for engaging a radially outer portion of the tyre. A checking device includes a mechanical arm and at least one sensor associated with the mechanical arm. The overturning device overturns the tyre around an overturning axis perpendicular to a rotation axis of the tyre when the tyre is in the operating space. The mechanical arm is operatively active within the operating space and carries the sensor at least partially within the tyre for executing checks on an inner surface of the tyre housed in the operating space.

Abstract: A process for building tyres employing a forming drum having circumferentially consecutive sectors that are radially movable between a contracted condition and an expanded condition in which the sectors are radially moved away from a geometric axis in order to define a radially external abutment surface. Each sector has circumferentially opposite coupling portions each having circumferential projections alternated with circumferential cavities. The projections of each sector are slidably engaged in the respective cavities of circumferentially adjacent sectors. From at least one of the projections, at least one support wing is extended having a first side and a second side that are respectively opposite. The first side coincides with a portion of the abutment surface and the second side at least partially overlaps one of the projections belonging to an adjacent sector.

Abstract: A process for manufacturing tyres for vehicle wheels includes associating at least one reinforcing structure with at least one surface portion of at least one tyre component laid on a forming support, wherein associating the at least one reinforcing structure includes bringing, through a handling and deposition member, at least one reinforcing element to the forming support and depositing, through said handling and deposition member, the reinforcing element on a respective deposition part defined on a surface portion of the component. The depositing includes gradually laying the reinforcing element on the deposition part following the profile of the deposition part in a circumferential direction.

Abstract: A method for building tyres for vehicle wheels is described. Second stage forming drums are moved in a crown structure building line for building respective crown structures. Movement occurs along a first path for building a first part of components of the crown structure and a second path for building a second part of components of the crown structure. Additionally, first stage forming drums are moved in a carcass structure building line for building respective carcass structures. The flow of the second stage forming drums is managed through a first manipulator, while the flow of the first stage forming drums is managed through a second manipulator.

Abstract: Building the carcass structure of tyres for vehicle wheels includes associating, at each end edge of a carcass ply, at least one respective annular reinforcement structure formed by depositing along a circumferential direction a plurality of reinforcement elements having a first length. Such elements are cut to size from a reinforced continuous band-like element fed to a cutting group arranged at a first operative position adapted to allow a barycentric grip of the reinforcement elements. The cutting group can translate along a feeding direction of the band-like element to a second operative position for cutting to size a plurality of second reinforcement elements having a second length different from the first length. The second operative position is defined on the basis of the second length, so as to have a barycentric grip of the second reinforcement elements too.

Abstract: In a process for building tyres for vehicle wheels, at least one tread band (9) or other elastomeric component of a tyre (2) is made by applying at least one continuous elongated element (14) according to a plurality of turns (C) around a forming drum (15) rotating around a geometric rotation axis (X) thereof. The continuous elongated element (14) is made by the action of extruding a first material through an extrusion nozzle (16), to form an inner core (33) of said continuous elongated element (14) exiting from an outlet opening (18) of the extrusion nozzle (16). During the extrusion, a second material different from the first material is conveyed around the first material, at the extrusion nozzle (16) and upstream of the outlet opening (18), to form a coating layer (32) which entirely surrounds the inner core (33).

Abstract: A process for building tyres for vehicle wheels includes: forming a tyre in process, the tyre including a belt structure and depositing a tread band in a position radially external to the belt structure by winding a continuous elongated element made of elastomeric material according to axially adjacent or partially overlapped coils. During the deposition of the tread band and on at least one of the coils already wound, a conductive liquid elastomeric compound is applied, the compound continuously extended between a radially outer surface of the tread band and a radially outer surface of the belt structure to generate electrically conductive paths and free zones.
