Abstract: A tire building core manipulating apparatus for a segmented tire building core is provided, the core including a plurality of core segments extending generally radially from a central axis. The manipulating apparatus includes a support frame; a core latching mechanism mounted to the support frame for operatively engaging a mating mechanism on the core whereby suspending the tire building core in a preferred axial orientation and raises and lowers the core to engage one or more stations in a tire curing line. A transport mechanism relocates the support frame with the tire building core in the preferred axial orientation between a plurality of stations in the tire curing line.

Abstract: A tire building core assembly is provided including a segmented toroidal core formed by a plurality of core segments configured in a closely adjacent array defining an outer tire-building toroidal surface. The tire building surface is configured having tire tread and sidewall build locations. Adjacent core segments provide adjacent and opposed annularly directed peripheral edge surfaces, opposed edge surfaces having interlocking elements that selectively engage to operatively deter relative radial movement between the adjacent core segments. The interlocking elements selectively disengage to operatively facilitate a disassembly of the segmented toroidal core.
Abstract: A core segment manipulating apparatus and method is provided for relocating core segments forming a toroidally shaped core body configured to carry a cured tire. The apparatus includes multiple core key segment engaging mechanisms and core second segment engagement mechanisms arranged in a spaced apart circular array adjacent to respective key segments and second segments of the core body. The key segment and second segment engaging mechanisms operate to individually move respective key segments and second segments from a radially outward core body position to a radially inward segment removal position. The key segment and second segment engaging mechanisms transfer a respective segment to a segment removal device at the segment removal position and return radially outward to a segment-receiving location.

Abstract: A station apparatus method within a tire curing line is provided for assembling and disassembling a toroidally shaped core configured to carry a cured tire. The core includes a plurality of core segments assembling to form a core body and extending generally radially from a central core axis within a core central axial passage. The core further includes first and second locking spindle sections connecting to opposite sides of the core body.
