Abstract
A bladderless tire-curing press has upper and lower pressing disks cooperating with upper and lower bead rings. The pressing disks have circumferentially continuous outer surfaces engaging the beads and bounded inwardly by axial projections with conical centering surfaces which engage in recesses in the bead rings. The bead rings have projections engaging in grooves between the projections of the disks.
Claims8
A bladderless tire-curing press, comprising:
- a lower bead-shaping member;
- an upper bead-shaping member spaced above and coaxial with said lower bead-forming member;
- an outer segmental tire-body-shaping member positionable with said upper and lower bead-shaping members to form an exterior of a green tire carcass into outer surfaces of a vulcanized tire body;
- a lower pressing disk juxtaposed and coaxial with said lower bead-shaping member, engageable with a lower bead of said carcass and having an outer diameter greater than a diameter of said lower bead, said lower pressing disk being movable axially relative to said bead-shaping members;
- an upper pressing disk juxtaposed and coaxial with said upper bead-shaping member, engageable with an upper bead of said carcass and having an outer diameter greater than a diameter of said upper bead, said upper pressing disk being movable axially relative to said bead-shaping members and independently of axial movement of said lower pressing disk;
- and
- respective displacing means connected to said pressing disks for axially displacing same,
- said pressing disks each having an annular circumferentially continuous pressing surface radially overhanging and axially juxtaposed with a pressing surface of the respective bead-shaping member,
- each of said pressing disks further having at least one axial projection having in axial view at least a circular arc-segmental configuration inwardly bounding the respective annular circumferentially continuous pressing surface and formed with a conical outer surface,
- said bead-shaping members having respective recesses complementary to said projections and receiving same in a closed position of the press.
