  • Method and apparatus for manufacturing tyres for vehicle wheels
    Patent number: 8048247
    Abstract: In a method for manufacturing tyres for vehicle wheels, a green tyre, once formed, is transferred into a vulcanisation mould and pressed against the holding walls of a moulding cavity. Concurrently with the pressing step, a fluid present between the green tyre and the holding walls is evacuated through vent valves. The tyre is brought into contact with the closing head of each valve so as to push it toward a closed position of the valve itself. The closing head has a distal portion facing the moulding cavity and includes at least one grip element for the tyre blend, so that the closure member is pulled toward the open position while the moulded and cured tyre is moved away from the inner surface of said moulding cavity.

  • Method and Apparatus for Manufacturing Tyres for Vehicle Wheels
    Publication number: 20090095406
    Abstract: In a method of manufacturing tyres for vehicle wheels, a green tyre, once formed, is transferred into a vulcanisation mould and pressed against the holding walls of a moulding cavity. Concurrently with the pressing step, a fluid present between the green tyre and the holdling walls is evacuated through vent valves. The tyre is brought into contact with the closing head of each valve so as to push it toward a closed position at which the closing head forms a contact seat spaced apart from the inner surface of the moulding cavity in order to define an embedding recess between the inner surface of the moulding cavity and the closing head.
