    摘要： In the building of a carcass structure for tires of vehicle wheels, the step of reinforcing with a loop at least one annular anchoring structure associated at the axially opposite end edges of a carcass ply is carried out on at least one radially expandable/contractable service drum and includes the steps of: setting the service drum to a predetermined radial dimension selected according to the fitting diameter of the tire to be manufactured, depositing the loop on the service drum, loading the annular anchoring structure onto the service drum in a radially outer position with respect to the loop, radially expanding the service drum up to lock in position the annular anchoring structure, rotating the service drum about a longitudinal axis thereof and, during the rotation, turning the loop up about the annular anchoring structure.

    摘要： An intermediate article of manufacture formed as a first stage bead area subassembly for a split ply pneumatic tire carcass is disclosed. The bead area subassembly has an annular bead core; a bead apex; a ply strip; and preferably a sidewall affixed to the ply strip. The subassembly is formed into a disk-shaped bead area monocomponent. The ply strip is wrapped about the bead core and the apex to form a ply turnup and both the ply strip and the ply turnup extend radially outwardly from the bead core. The bead area subassembly when formed into the disk-shaped bead area monocomponent is placed on an annular holder device. The combination of the bead area monocomponent on the holder device can be stacked for storage and latter assembly into a split ply carcass. Preferably, the ply turnup can be oriented extending inside or axially inward of the bead core on final assembly to form a split ply tire having axially inside turnups. In the preferred embodiment the ply strip is reinforced by radially extending ply cords.

    摘要： Separation in a chafer edge is suppressed, thereby improving durability of a bead part. In a pneumatic tire including a bead core embedded in a bead part, a carcass ply folded around the bead core and locked, and a chafer having a reinforcing cord embedded therein arranged so as to cover the carcass ply around the bead core, a rubber sheet is prepared using a wet masterbatch containing natural rubber and/or polyisoprene rubber, and carbon black, and the rubber sheet is interposed between a folded part of the carcass ply and an edge of the chafer overlapping the folded part.

    摘要： In the building of a carcass structure for tyres of vehicle wheels, the step of reinforcing with a loop at least one annular anchoring structure (10) associated at the axially opposite end edges of a carcass ply is carried out. Said reinforcement step is carried out on at least one radially expandable/contractable service drum (107a, 107b) and comprises the steps of: setting the service drum (107a, 107b) to a predetermined radial dimension selected according to the fitting diameter of the tyre to be manufactured, depositing the loop (5) on the service drum (107a, 107b), loading the annular anchoring structure (10) onto the service drum (107a, 107b) in a radially outer position with respect to the loop (5), radially expanding the service drum (107a, 107b) up to lock in position the annular anchoring structure (10), rotating the service drum (107a, 107b) about a longitudinal axis (X-X) thereof and, during such a rotation, turning the loop (5) up about the annular anchoring structure (10).
