Abstract: A method of making a green tire comprises: winding a carcass ply of rubberized cords around a building drum into a substantially cylindrical body; pressing the cylindrical body against the building drum through the entire circumference not to allow the carcass cords to move axially and circumferentially of the drum; constricting edge portions of the substantially cylindrical body so that the outer diameter thereof is decreased; setting a bead core around each of the constricted edge portions; folding back the edge portions around the bead cores; releasing the cylindrical body from the pressing against the building drum after the edge portions are constricted at the earliest; and swelling a main portion of the cylindrical body between the bead cores while decreasing the width between the bead cores.

Abstract: Method and apparatus for manufacturing pneumatic tires, wherein a green case comprised of at least one inner liner rubber member and a carcass ply member is formed on a first drum and transferred to a position around a second drum. The green case is the fixedly secured to the second drum by axially moving a pair of centering elements in opposite directions into pressure contact with opposite inner sides at the bead portions of the green case, and urging the inner peripheries of the bead portions by a pair of lock elements. The second drum is then caused to expand and undergo a width reduction, thereby expanding the green case into a toroidal shape. Sidewall rubber members, which have been previously wound on a pair of side bladders on the outer side of the lock elements, are expanded and reversed by inflating the side bladders and joined to the toroidal green case to thereby form a green tire.

Abstract: Expandable drum for constructing a green carcass of a tire has a periphery and includes a plurality of metal segments positioned to form a substantially cylindrical arrangement, adapted for radial expansion and compression. A thick-walled casing, positioned over the plurality of metal segments, forms the drum periphery. The thick-walled casing includes rubber and a plurality of voids arranged to have an outer periphery in the thick-walled casing. An evacuating pump is coupled to the plurality of voids. The plurality of voids form suctioning voids to suction the green carcass onto the drum periphery during compression of the drum periphery, and are coupled at radially outermost extents to a network of grooves arranged to provide wave-free and smooth contraction of green carcass during its compression, thereby avoiding bulges and creases in contracting green carcass. Radially innermost extents of the voids are coupled to evacuating pump to create vacuum in the grooves.

Abstract: Process and drum for constructing a green tire on a radially expandable drum having a substantially horizontal axis of rotation. The process includes collapsing the radially expandable drum at a minimum first diameter, and positioning a casing on the radially expandable drum to form a drum periphery being composed of an elastic material, and having an inner diameter at least as great as the first diameter, and including a plurality of voids coupled to an evacuating pump. The radially expandable drum is radially expanded from the first diameter to a second diameter greater than the first diameter to expand the casing, and producing a carcass, having at least one carcass ply with at least one of sidewalls and an air-tight inner layer, on the drum. A vacuum is produced in the voids to suction the carcass onto the drum periphery and at least axial end areas of the expandable drum are radially compressed to a third diameter to enable bead cores to traverse the drum periphery without touching the drum periphery. The bead cores are slid over at least the axial end areas of the drum periphery and are axially positioned over the axial end areas of the drum periphery, which are radially expanded at least the axial end areas of the radially expandable drum to a fourth diameter sufficient to radially compress the bead cores and the carcass against each other, providing adequate bonding between a bead core inner surface and a carcass external surface. The fourth diameter is substantially the same as the second diameter, the radially expandable drum is radially compressed to a fifth diameter between the first and second diameters, and the carcass with set bead cores is pulled off the radially expandable drum for further processing in a preshaping device. Upon conclusion of the bead core placement, the carcass is substantially free of compressive stress and tensile stress.
