| 20090159215 | TIRE CURING BLADDER - An expandable bladder for shaping a pneumatic tire is provided. The bladder in an unmounted, relaxed state has a shaped body having a pair of opposed annular beads, said body further comprising a central portion, sidewall portions, and shoulder portions interposed between the central portion and the sidewall portions, wherein the body is defined by an outer contour surface and an inner contour surface, wherein the central portion has gauge which increases to a maximum value axially inward of the shoulder portion, and wherein the bladder gauge in the shoulder is less than the maximum value, and wherein the bladder gauge increases from the shoulder to the bead. | 06-25-2009 |
| 20110017403 | Rigid Core for Making Tires - A rigid core which at least partly defines a manufacturing form for the inside surface of a tire, the core comprising a plurality of circumferentially adjacent segments ( | 01-27-2011 |
| 20120037318 | Transfer ring which resists backdriving forces during a tire construction process - A transfer ring for supporting a belt and tread package about a tire carcass for inflation of the carcass within the package during a tire-making process includes a plurality of shoes which are movable inwardly and outwardly for purposes of grasping or releasing a package positioned between the shoes. Components are provided for moving the shoes inwardly to a radial position about a package; and at this radial position, the shoes apply to the package a biasing force for maintaining a substantial uniform pressure about the package if it were to contract in size after the shoes are moved to the radial position. A braking arrangement is provided which prevents the shoes from moving outwardly of the radial position when a tire carcass is thereafter inflated within the package to thereby limit the diameter of the package during the carcass-inflating process. | 02-16-2012 |

Relative traversing motion between rotating tire supporting structure and pressing or bending means | 1 |
| 20080245482 | Belt for use in forming a core of plies, beads and belts of a urethane tire - A belt for incorporation into a core of plies and beads formed on a tire core build mandrel where the core is for encapsulating in an elastomeric material, preferably a polyurethane, in a tire formation process, and which belt is formed from like belt sections laid over one another where the one belt section is rotated approximately one hundred eighty degrees around its longitudinal axis with respect to the other, and the belt sections are individually mounted around a tire core build mandrel top whereover a plies has been fitted and with the pair of belt sections ends off-set from one another and are fitted together into a continuous belt. Each belt section is a weave of lateral and longitudinal cotton cords or filaments containing straight, spaced, parallel, taut, Rayon warp cords where the Rayon warp cords or filaments have a crossing angle of forty to sixth degrees respectively, with the stack of a two belt sections forming a tire belt. | 10-09-2008 |

Stitching elements, per se | 1 |
| 20100108266 | Tire sidewall stitcher - A hand tool for closing splices and correcting flaws arising during tire fabrication includes an elongated body member having a butt end, a front end, a top, and at least one side at a substantially right angle to the top; and a handle member is disposed at the butt end of the body member. An arm is fixedly attached to the handle or an interior side of the elongated body member and a metal wheel is rotatably attached to a protruding portion of this arm. A gripping knob is disposed atop the front end of the elongated body member for enabling downward pressure on the wheel. | 05-06-2010 |

| 20090095427 | MANUFACTURING METHOD OF TIRE FORMING MOLD AND TIRE FORMING MOLD - A manufacturing method of a tire forming mold in which an annular mold portion is constituted by a combination of sectors includes a step of manufacturing a circular arc shaped inner segment provided with a concavo-convex shape, a step of dividing the inner segment by a non-flat surface division so as to obtain a first segment piece and a second segment piece, and a step of incorporating the first segment piece into an inner peripheral side of a back segment of one sector out of a pair of sectors which are adjacent to each other in the tire circumferential direction, incorporating the second segment piece into an inner peripheral side of a back segment of the other sector, and arranging the non-flat surface divided surface in an end surface of the sector. | 04-16-2009 |
| 20100212835 | COMBINED ENVELOPE FOR TIRE RETREADING - Combined envelope for tire retreading basically comprises a single body ( | 08-26-2010 |
| 20110232848 | ARRANGEMENT IN TIRE RETREADING ROLLING MACHINE FOR TIRES RECAPPING - The present disclosure relates to an arrangement in a tire retreading rolling machine including a structure composed of a lower frame (Q) provided with adjustable feet (P) and one column (C) on one of its vertices. Column (C) has on its outer side a motoreducer set (MR) which rotates a hub (CB) positioned on the column inner side. A bearing (M) held to column (C) supports the hub (CB) shaft, on which the tire to be processed is mounted. The rolling device mounted on the frame (Q) comprises arms ( | 09-29-2011 |
| 20120145328 | TIRE EXTRACTOR APPARATUS - A tire support device is disclosed having an annular support member having an inner surface and an outer surface. A support flange is mounted to the annular support member, the support flange has an inflatable bladder mounted into its inside surface. The inflatable bladder has an inflated position for supporting the tire and an uninflated position for releasing the tire. | 06-14-2012 |
| 20120145329 | TIRE SUPPORT APPARATUS - A tire support device for supporting the bead area of a tire is described. The tire support device includes an inner support member having a plurality of support vanes mounted to the support member, the support vanes radially extend from the inner support member. The tire support device further comprises a plurality of cover plates forming an outer cylindrical surface for supporting the bead area of a tire. The cover plates having an inner rib which extends radially inward, said rib having one or more guide members, each slide member slidably mounted on the support vane, wherein the guide members are slidably from a radially inward position to close the cover plates, and to a radially outward position to radially expand the tires. | 06-14-2012 |
