    摘要： A tire building drum and a method of building a tire carcass is disclosed. The tire building drum has a center section comprised of a plurality of segments that are radially and axially movable. The sleeve of the tire building drum over the center section has been eliminated, and instead has two seals located on the outer ends or shoulders of the center section of the tire building drum. The building drum further comprises shoulder sections that are axially movable. The shoulder sections include radially expandable bead locks. The method employs the steps of applying one or more carcass layers, locking the bead locks and moving the center section radially outwardly while moving the bead locks axially inwardly.

    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： Apparatus and methods of forming a tire. A drum has an expansion device that is configured to turn-up the lateral ends of the tire carcass about respective bead-and-apex assemblies while generally maintaining a constant orientation of the bead-and-apex assemblies. Further, the expansion device turns-up the lateral ends of the tire carcass while at the same time radially expanding the tire carcass. The methods entail turning-up the lateral ends of the tire carcass around the bead-and-apex assemblies and also moving a portion of the tire carcass lying between the bead-and-apex assemblies in a radially-outward direction relative to an axis of rotation of the drum.
