    Abstract: A method of molding a green tire having a first and second bead area is described herein, wherein the method includes the steps of: inserting a tire clamping device inside a tire bladder and then inserting the tire clamping device and the bladder into the green tire, aligning the outer surfaces of the tire clamping device into engagement with a respective bead area of the tire so that each tire bead area is clamped between a respective upper and a lower mold ring and the tire clamping device during cure. A tire clamping device includes an inner portion, and a plurality of segments connected to the inner portion, wherein the tire clamping device has a closed position wherein the plurality of segments together forms a first and second ring for engagement with the bead areas of the tire so clamp the bead areas between the clamping device and the mold rings during cure.

    Abstract: The present disclosure is related to a curing ring that can be utilized in a tire mold to cure elastomer bands for NPTs or for tread band assemblies used in tire retreading. In one or more embodiments, the tire mold can comprise a base plate having a plurality of channels oriented along a radial direction. The tire mold can also comprise a plurality of inner segments configured to engage an inner radius of the elastomer band. Each inner segment includes an optional anchor for reception into a respective channel of the plurality of channels. Also, the plurality of inner segments can be configured to translate along the radial direction. Further, the tire mold can comprise a plurality of outer segments configured to engage an outer radius of the elastomer band.

    Abstract: A method of building a tire carcass is disclosed. The method of building the tire carcass includes the steps of applying one or more tire building components onto a drum forming a cylindrically shaped tire carcass. Placing a first and second bead onto the tire building components on the drum so that the tire carcass ends of the tire carcass extend laterally between the beads. Radially expanding a first and second bead lock mechanism into engagement with a respective first and second bead. Inflating the carcass under low pressure into engagement with a belt and tread package while moving the beads axially inward. Moving the beads axially inward to the axial width of the widest breaker position; Turning up the outer lateral ends of the cylindrically shaped tire carcass about a respective first and second bead.

    Abstract: The tire building drum includes a rotatable drum having a center section and a first and second shoulder section. The center section is radially expandable, and the center section has a first and second shoulder, wherein the first and second shoulders are sloped. The method of building a tire includes the steps of applying an inner liner and a layer of ply to the drum and then a bead, locking the bead into position, applying an apex to each of the sloped shoulders, turning up the ply over the bead and the apex, and then applying a down ply over the ply ending.
