Abstract: A multi-function end effector includes a plurality of tool change mechanisms in a housing in which a spindle is also mounted for translation along an axis of the spindle. Each tool change mechanism has a gripper that releasably grips a tool holder in which a tool is mounted. The gripper of each tool change mechanism is movable between a stowed position to a tool-change position in which the gripper is coaxially aligned with the axis of the spindle for placing a tool holder held in the gripper in a position to be received by the spindle and for positioning the gripper to receive a tool holder from the spindle. The tools mounted in the tool holders include a drill bit, a countersink tool, and a fastener insertion tool. The end effector also includes a fastener feed system, a hammer device, and a sealant applicator.

Abstract: An apparatus for building a tire having an inner liner to which a sealant strip is to be laminated, comprises a rotary drum having a surface in which a trough or "groove" is provided. The depth of the groove corresponds approximately to the thickness of a layer of an elastomeric sealant which is to be placed in the groove. If the walls of the groove are contoured so as to confine the sealant layer in a specified manner while accommodating the thermo-viscous properties of the laminate, the completed first stage carcass may be removed without damaging the sealant layer which is adhered to the inner liner.
