ABSTRACT:
An unloader for a tire curing machine is improved in that a tire gripping device in the unloader is composed of a chuck base for depressing an upper bladder clamp ring upon lowering an arm which supports the tire gripping device to form a space for inserting chuck claws between inner circumferential portions of a bladder and a cured tire, chuck claws mounted on the chuck base so as to be expansible and contractible, and a chuck claw expansion/contraction hydraulic cylinder mounted on the chuck base.
