    摘要： A tire forming drum includes a pair of bead lock devices, a shaping device, ply turning-up devices for turning up a ply, and a plurality of stitching supports circumferentially arranged between the pair of bead lock devices. Each of the stitching supports is composed of a rigid lever having one end pivotally connected to a housing of one of the bead lock device and the other end provided with a close contact portion to be brought into close contact with an inner circumferential surface of one bead portion of a tire being formed. An actuating device for each of the stitching supports is composed of a rigid link having one end pivotally connected to a mid portion of the stitching support and the other end pivotally connected to one of sleeves movable in axial directions of the forming drum. The stitching supports are able to expand by movements of the sleeves and the bead lock devices arranged on both sides toward each other.

    摘要： The folding-up system is intended to fold an end portion of a cylindrical wall of a tire carcass assembly around a reinforcing bead core. The system comprises a drive device that is arranged to cause the carcass assembly to revolve intermittently about its roll axis, by successive angular increments, together with a folding device to cause pressure rollers to tilt. After each angular increment in roll, about a pitch axis perpendicular to the roll axis, in order to fold each portion of the end section located in an angular working sector occupied by a pressure roller towards the radially inner face of the wall, around the reinforcing bead core. Finally, the drive device includes a selector for placing the pressure rollers in a withdrawn position to disengage the trajectory followed by the wall of the carcass assembly during its roll rotation.

    摘要： The present invention provides a tire building, and a building system, process setup method and manufacturing method for a tire built by this tire building drum, which can suppress investment cost of the drum core of the tire building drum used in a tire building system for building tires in different sizes, and to shrink an inventory of reserve drum cores. Plural distance pieces having the same thickness and end pieces forming the both end portions in the width direction are aligned in the width direction of the drum core to configure plural rigid segment which constitute the tire building drum. The distance pieces which are detachably configured are so arranged that their thickness direction face in the width direction of the drum core.
