Rigid core mold removal device and tire manufacturing method
10449741 · 2019-10-22 · ·

A method for manufacturing a tire T comprises a step for forming a green tire on the outside of a rigid core mold 2, a step for vulcanization-molding and obtaining a tire-accompanying rigid core mold G, a step for setting, at an assembly station P3, a core 5 taken out from the tire-accompanied rigid core mold G, and a removal and assembly step for removing one core segment 3 from the tire T by moving in inwardly in the tire radial direction from the tire-accompanying rigid core mold G and mounting it on the core 5 set at the assembly station. The removal and assembly step is performed for every core segment in the tire, whereby a rigid core mold 2 is assembled at the assembly station P3, while removing the rigid core mold 2 from the tire T.

Bladder-fixing unit
09969139 · 2018-05-15 · ·

A bladder-fixing unit fixes a bladder which expands in a tire to hold the tire, the bladder-fixing unit includes a shaft body inserted into the bladder, and a connecting body for fixing the bladder and for connecting the bladder and the shaft body to each other, the connecting body includes a switching mechanism for switching between a state where the connecting body pressurizes and comes into contact with an outer periphery of the shaft body and is fixed to the shaft body, and a movable state where the connecting body can move in an axial direction of the shaft body relative to the shaft body by releasing the state where the connecting body pressurizes and comes into contact with the outer periphery of the shaft body.
