  • Patent number: 12479177
    Abstract: The facility comprises a tire-building station that is configured to form an uncured tire on a core. A curing station is configured to cure the assembly formed by the core and the uncured tire so as to obtain a cured annular tire. An extraction station is configured to separate, after the curing operation, the cured tire from the core. The curing station has a first, heating, thermal source which presses against the exchange face of the core for the curing operation and is then dissociated from the core and remains in the curing station in order to leave the exchange face free again when the core and the cured tire are transferred to the extraction station so that a second, refrigerating, thermal source of the extraction station takes the place of the first thermal source in contact with the exchange face of the core so as to cool the core.

  • Publication number: 20250010661
    Abstract: An assembly device for assembling an airless tire (2) that comprises a hub (3) having a central axis (Z3), a peripheral annular band (4) and a plurality of spokes (5) that connect the hub (3) to the peripheral annular band (4), comprises a plurality of pressing sub-assemblies (10) each comprising pushers (11, 12) to press the ends (6, 7) of the spokes (5) against the hub (3) and against the peripheral annular band (4), respectively, as well as a punch (13) that is mounted movably in axial translation parallel to the central axis (Z3), and provided with ramps (15, 16) arranged so that the axial movement of the punch causes the pushers (11, 12) to move radially.

  • Patent number: 10967591
    Abstract: A tire manufacturing method and system is provided for controlling a product profile having one or more elastomeric layers that are produced by continuously extruding an elongated element (200) of an elastomeric material and depositing the elongated element (200) upon a forming surface (100a) of a circumferentially rotating drum (100).
