摘要： A radial tire is provided with a metal belt comprising two load-bearing strips, respectively a first one and a second one, with reinforcing elements inclined in opposite directions in the two strips relative to the equatorial plane, and a pair of lateral bands radially superimposed on the ends of the second strip. The second strip has an axial width less than the first one and has edges staggered axially inwards with respect to the edges of the first strip. Each band comprises a single layer of circumferential metal reinforcing elements and has its axially external edge staggered axially inwards with respect to the edge of the second strip. A third strip with inclined reinforcing elements is arranged in the radially outermost position of the belt and covers at least two thirds of the width of each band. The pair of bands covers at least partially the two ends of the second strip in a diverging configuration relative to the two ends of the first strip.

摘要： Equipment for molding and curing a green tire includes a curing mold including a first bead molding ring including a first surface for contacting a radially inner and axially inner surface portion of an annular fixing structure of the green tyre and a first sidewall plate including a second surface for contacting a radially inner and axially outer surface portion of the annular fixing structure. The first bead molding ring is radially extendable from a contracted operating position to an expanded operating position so as to delimit a portion of the annular fixing structure between the first sidewall plate and the first bead molding ring, and the first bead molding ring is translatable towards the first sidewall plate for generating a first squeezing pressure on the annular fixing structure. The equipment further includes an inflatable bladder associated for operation with the curing mold.

摘要： A carcass ply is applied around an outer surface of a building drum, according to an application diameter greater than the fitting diameter of the tire. An annular anchoring structure defining the fitting diameter is coaxially engaged around each of the end flaps. An outer sleeve including at least one belt structure possibly associated with a tread band is disposed at a coaxially centered position around the carcass sleeve applied onto the building drum. Through axial approaching of two halves forming the building drum, the carcass sleeve is shaped into a toroidal configuration to determine application of same against a radially internal surface of the outer sleeve.

摘要： Two auxiliary support members are operatively engaged with a building drum, in axially approached relationship with respective halves of the drum itself, each auxiliary member having a circumferential rest surface extending in the continuation of an outer circumferential surface of the building drum itself. Applied around the outer circumferential surface of the building drum is at least one carcass ply having axially opposite end flaps each lying on the circumferential rest surface of the respective auxiliary support member. A pair of auxiliary shaping members engaged with the building drum in place of the auxiliary support members, each act against a circumferential abutment edge carried by the building drum, to enable the carcass ply to be shaped into a toroidal configuration concurrently with mutual approaching of the halves of the building drum.

摘要： A plurality of strip-like elements is applied onto a forming drum externally having a substantially cylindrical laying surface. The strip-like elements are disposed in mutually approached relationship to form at least one first annular reinforcing layer on the forming drum itself set to a first work diameter at which each of the applied strip-like elements on the laying surface subtends an arc of a circumference of a width as large as a submultiple integer of the overall circumferential extension of the laying surface itself. Adjustment devices operating on the forming drum subsequently carry out expansion of the latter to a second work diameter larger than the first work diameter, while maintaining its laying surface substantially cylindrical.

摘要： In an assembly station a carcass sleeve and an outer sleeve manufactured along respective building lines are mutually coupled. Integrated into the assembly station are engagement devices that can be alternatively coupled to an auxiliary drum carrying an outer sleeve and to a building drum carrying a carcass sleeve. A grip unit picks up the outer sleeve from the auxiliary drum associated with the engagement devices in order to position it to a location radially external to the carcass sleeve carried by the building drum associated with the engagement devices in place of the auxiliary drum. Shaping devices that can be operatively coupled to the building drum cause radial expansion of the carcass sleeve so as to enable the latter to be coupled to the outer sleeve retained by the grip unit.
