Abstract
Apparatus for positioning a partially shaped, uncured tire carcass and a tire curing bladder of a lower half-section of a vulcanization mold relative to one another, is disclosed. The apparatus includes the lower half-section of a vulcanization mold from which a inflatable, tire curing bladder extends axially upwardly, the bladder being axially and radially expansible and contractible. A bladder-con-trolling piston rod is associated with the lower halfsection and is used to axially elongate the bladder and thereby radially contract the latter. A circumferentially expansible-contractible tire carcass transporter is associated with the lower half-section and is effective to position a generally toroidally shaped. uncured tire carcass concentrically around the bladder, with the lower bead of the tire in contact with the upper inner surface of the lower half-section. A downwardly projecting cylinder and piston rod assembly is carried concentrically in and by the tire carcass transporter. The piston rod thereof when protracted is axially engageable with the aforementioned bladder-controlling piston rod to cause the latter to retract and thereby radially swell and fit the bladder into the interior of the uncured tire carcass. Steam injected into the bladder is used to assist the swelling of the latter, and subsequently to in part cure the tire carcass after it is released by the transporter and covered by an upper half-section of the mold. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
