ABSTRACT:
A tire building and cure station coupling apparatus and method for molding a green tire into a finished tire having a tread pattern. The green tire is constructed on a toroidally shaped core formed by a plurality of core segments each having an outer surface portion which together define a toroidal outer surface surrounding a central axis. The core is adapted to hold a green tire on said toroidal outer surface. A first spindle section is configured to be placed on a first side of the core along the central axis and a second spindle section is configured to be placed on a second side of the core along the central axis and opposite to the first side. At least one electrically operated heating element is coupled with each said core segment and at least one spindle connector is configured to mechanically couple the first and second spindle sections with said plurality of core segments located therebetween and electrically connect with the electrically operated heating elements for supplying electrical power thereto during a tire curing operation. One or more curing line docking stations are provided, each having docking apparatus for mechanically coupling with a spindle end of a spindle sections for a docking time interval, the docking apparatus including a docking connector configured to mechanically and electrically couple with the spindle connector for supplying electrical power to the electrically operated heating elements for at least a portion of the docking time interval.
