摘要： Along a building line, a green tyre is built on a rigid toroidal support having an outer surface substantially conforming in shape to an inner surface of the green tyre. The green tyre is then transferred to a bead moulding and prevulcanisation station where each bead of the tyre is moulded by tightening it between a surface portion of the toroidal support and an annular clamping surface carried by a removable tightening flange. The tightened beads are prevulcanised through a heat supply by means of electric resistors integrated into the tightening flanges. The tyre with the prevulcanised and tightened beads is transferred into a moulding cavity having an inner wall of a shape substantially conforming to that of the outer surface of the moulded tyre, to carry out moulding of the tyre and complete vulcanisation of same.

摘要： A tire holding mechanism includes a first support body, a second support body and a moving device. The first support body is provided with a substantially annular first flange which supports a first bead at one side of the tire, a lock shaft having a lock mechanism and which protrudes in an axial direction of the first flange to allow the first flange to move in the axial direction, and a stopper which restrains the first flange at the proximal end of the lock shaft. The second support body is provided with a substantially annular second flange which supports a second bead of the tire, and an engagement portion with which the lock mechanism is removably engaged. The moving device moves the first support body between a tire holding position and a tire transferring position. The lock mechanism is engaged with the engagement portion at the tire holding position.

摘要： A mold rotator with a first section and a second section that are engaged approximately perpendicularly to each other to produce a base and an L-shaped platform for receiving the article. The base of the article rotator may have a curved section at the intersection of the first section and the second section and the article rotator may rotate on its curved section between a first position wherein the article rotator is supported on its first section and a second position wherein the article rotator is supported on its second section. Further, the article rotator allows an article to be safely rotated simply by lowering the article onto the article rotator so that the article rotator automatically rotates approximately 90° from a first position and a second, rotated position. The article rotator may include a stabilizing system.

摘要： Loading apparatus and method for positioning a green tire and core assembly into a toroidally shaped mold includes a stand assembly having a support surface operatively receiving a first mold sidewall forming segment thereon, the surface having a central opening. A spindle engagement assembly projects upwardly through the support surface central opening and includes a coupling mechanism at a forward end operatively mating with a first spindle end of a tire building core. The coupling mechanism operatively suspends a sidewall of a green tire on the tire building core a distance above a first mold sidewall forming segment positioned on the stand support surface. The spindle engagement assembly moves axially between a raised position and a lowered position and, in the lowered position operatively places the sidewall surface of the green tire on the first mold sidewall forming segment.
