Band Drum Pop-Up Hinge

摘要

A tire building apparatus includes a tire building drum having a radially expanded position for building a tire carcass, and having a radially contracted position for releasing the tire carcass. A carcass release member is mounted on the drum such that the carcass release member moves from a retracted position when the drum is in its expanded position, to an extended position when the drum is in its contracted position, so that the carcass release member aids in releasing the tire carcass from the drum when the drum moves from its expanded position to its contracted position.

主权项

1. A method of manufacturing a tire carcass, comprising:
(a) placing an inner layer of a tire carcass about a band drum when the band drum is in a radially expanded position, the band drum including at least one carcass release member retracted into an outer surface of the band drum when the band drum is in its expanded position; (b) radially contracting the band drum to release the tire carcass from the band drum; and (c) during step (b), moving the carcass release member outward relative to the outer surface of the band drum to aid in removing the tire carcass from the band drum.
