Appl. No.:

7/899766

Inventors:

Michael J. King - Concord CA
Paul E. Rier - Argyle TX
Robert A. Flynn - San Francisco CA

Assignee:

Oliver Rubber Company - Oakland CA

International Classification:

B29C 3502

US Classification:

425 17

Abstract:

An improved curing envelope is provided for use in a retreading or recapping process. The improved curing envelope includes integrally formed gas passageways in the inner circumferential wall thereof which permits the ingress and egress of gas into the interior of the curing envelope and retains pre-cured tread material in position for properly forming or securing the new tread to the carcass during the bonding process.

Assignee:

Oliver Rubber Company - Oakland CA

International Classification:

B29C 3500
B29D 3008
B29D 3054

US Classification:

156 96

Abstract:

A tire recapping and retreading method and apparatus that includes a rigid, segmented tread mold. The mold is retained in place over the tire carcass and uncured tread material by a resilient elastic tension band or prestressed metal tension springs. Further retaining force is provided by a resilient envelope to complete the formation of the retread when the tire and apparatus is placed in a hot air oven. The use of the rigid segmented mold described eliminates the distortion of the tire carcass by the mold.

International Classification:

B29D 3072

US Classification:

156 96

Abstract:

A method and apparatus for installing sidewall replacement members on a used tire carcass by attaching sidewall members to the pre-buffed and cement coated sidewalls of the tire carcass, covering each sidewall member with a flexible sidewall mold, placing a flexible curing envelope around said tire carcass including the sidewall molds and sealing the envelope in the bead area of the tire carcass. The envelope covered tire carcass is then placed in a curing chamber at a preselected temperature and pressures for time period sufficient to cure said sidewall members and bond them on said tire carcass. The sidewall members can be installed in conjunction with the installation of tread rubber on the tire.

Assignee:

Oliver Rubber Company - Oakland CA

International Classification:

B29C 7300

US Classification:

156 96

Abstract:

Tire recapping or retreading apparatus and method including the use of a tread mold with a plurality of mold segments. A tread mold loading machine is used to position the prepared tire carcass relative to the mold segments and to install the mold segments on the exterior of the tire carcass. The mold segments are retained in place on the exterior of the tire carcass by a tension band. Resilient elastic tension bands or pre-stressed metal tension springs hold the mold segments on the tire carcass after the mold segments have been released from the tread mold loading machine. The use of the tread mold loading machine and the mold segments eliminates distortion of the tire carcass during installation of the tread mold.
