ABSTRACT:
In combination with a tire casing, including a pre-formed, pre-cured, or uncured tread disposed about its periphery, and a curing envelope covering said tread and at least the outwardly facing side walls and bead portion of the tire casing, means are disclosed for effecting a tight and uniform seal between the said curing envelope and tire casing. These comprise a pair of annular sealing members, each having a central hub and a peripheral circumferential surface adapted to engage with the bead portion of the tire casing; a pair of unitary backing members, each having a central hub and portions at equal radial distances from the said hub which are engageable with the inwardly facing peripheral edge of said tire casing; and threaded fastener means extending between each said annular member and said backing member to enable the annular and backing members to be drawn toward one another to effect a clamping action between the members and intervening envelope and tire bead as the members are drawn together.
