Tire carcass building drum with inflatable bladders |
摘要 |
A tire carcass building drum is provided adjacent its ends with a shoe movable axially thereto which comprises a main shoe and a secondary shoe rotatably mounted by bearings on the main shoe. The secondary shoe is provided with turn-up bladders thereon, which bladders function to turn over extended ply ends around bead assemblies placed on other components of a tire carcass being assembly on the drum. The secondary shoe further includes a toe surface engageable with the ends of the drum to thereby render the bladder members rotatable with the drum surface. These bladders also provide a support for ply ends against which the consolidating and stitching rollers can act to smooth and press together the ply materials.
