A belt cover layer is formed by spirally winding belt cover materials including a first cover material and a second cover material. When one side in a tire width direction with respect to a tire equatorial plane is defined as a first side and another side is defined as a second side, the first cover material is disposed from a position between a shoulder region on the second side and the tire equatorial plane to a shoulder region on the first side. The second cover material is disposed from a position between the shoulder region (Ash) on the first side and the tire equatorial plane to the shoulder region on the second side. The first cover material and the second cover material have an overlapping portion at a position where positions in the tire width direction become positions identical to one another.

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.

The invention relates to a method and centering assembly (1) for centering a tire component (9), wherein the method comprises the steps of placing the tire component on and conveying it from a first conveyor (2) towards a second conveyor (3), determining the position of a first longitudinal edge (91), transversely moving the first conveyor (2) and thereby aligning the first longitudinal edge (91) along a first reference on the second conveyor (3), conveying the tire component from the first conveyor (2) onto the second conveyor (3) while determining the position of a second longitudinal edge (92), wherein the tire component has a center between the first longitudinal edge (91) and the second longitudinal edge (92), conveying the tire component from the second conveyor (3) towards a drum (4), laterally moving the drum (4) to align the center of the tire component with a center of a desired application position of the tire component on the drum, and conveying the tire component from the second conveyor (3) onto the drum (4).

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.

In a tire, a ribbon rubber includes a first inclined portion which is placed at a slant with respect to a tire-circumferential direction from an outer second row of a tire-width direction to an outer first row, a first parallel portion having an end connected to an end of the first inclined portion, the first parallel portion being placed parallel to the tire-circumferential direction to configure the outer first row of the tire-width direction, and an outermost inclined portion having an end connected to an end of the first parallel portion, the outermost inclined portion being placed at a slant with respect to the tire-circumferential direction. The outermost inclined portion is placed along the first inclined portion, and is placed outside of the outer first row from the outer first row of the tire-width direction.

A belt cover layer is formed by spirally winding belt cover materials including a first cover material and a second cover material. When one side in a tire width direction with respect to a tire equatorial plane is defined as a first side and another side is defined as a second side, the first cover material is disposed from a position between a shoulder region on the second side and the tire equatorial plane to a shoulder region on the first side. The second cover material is disposed from a position between the shoulder region (Ash) on the first side and the tire equatorial plane to the shoulder region on the second side. The first cover material and the second cover material have an overlapping portion at a position where positions in the tire width direction become positions identical to one another.
