    摘要： The invention is directed to a center deck assembly (100) for a tire building drum. The tire building drum is rotatably mounted on a central drive shaft and includes a center section (110) . The center deck assembly is disposed in the center section of the drum and includes a hub (112) that seats on and is secured to the central drive shaft. At least one piston (124, 126) extends circumferentially in the tire building drum about the hub and a plurality of segment bars (186) are disposed about the circumference of the center deck assembly. The at least one piston (124, 126) is operably connected to the segment bars by a plurality of linkages (154) , in which each of the linkages (154) includes a scissor-lever mechanism.

    摘要： A second stage tire building drum is disclosed. The drum (100) comprises a first and second hub (120, 120'), wherein each hub is mounted on a central shaft (110) of the second stage tire building drum (100); wherein at least one of said hubs (120, 120') is configured for unconstrained axial movement on the central shaft (110); and wherein each hub (120, 120') has a bead receiving mechanism mounted on each hub. Also, a method of forming a tire on a tire building drum (100) from a green tire carcass (600) is disclosed. The method comprises the steps of (i) applying a green tire carcass (600) onto the tire building drum (100) by placing a first and second bead onto a first and second respective bead receiving member of the tire building drum, wherein no bead locking force is utilized or (ii) applying a green tire carcass (600) onto the tire building drum (100) by placing a first and second bead onto a first and second respective bead pocket (212) of the tire building drum (100), wherein preferably a relatively low bead locking force is utilized and wherein at least one of the first and second respective bead pockets (212) are configured for unconstrained sliding in the axial direction. The method further comprises the step of inflating the carcass (600) into engagement with a belt and tread package (650) while at least one of the beads is free to move axially inward.
