摘要： A process and a plant for producing tyres for vehicle wheels are described. Building of a crown structure of the tyre includes building a crossed belt structure on a substantially cylindrical first forming drum, transferring the crossed belt structure from the first forming drum to an annular holding member, positioning a second forming drum in a radially inner position with respect to the annular holding member, transferring the crossed belt structure from the annular holding member to the second forming drum by radially expanding the second forming drum until it is brought into contact with the crossed belt structure so as to toroidally shape the crossed belt structure, and depositing at least one zero degrees belt layer on the second forming drum in a radially outer position with respect to the toroidally-shaped crossed belt structure.

摘要： A method for building belt assemblies for tyres for vehicle wheels is described. The method includes building a crossed belt structure on a forming drum. Depending on the type of tyre to be produced, the method selects whether to build a belt assembly having a cylindrical shaping or a belt assembly having a toroidal shaping. In order to build a belt assembly having a cylindrical shaping, zero degrees belt layer is deposited on the forming drum in a radially outer position with respect to the crossed belt structure. In order to build a belt assembly having a toroidal shaping, the crossed belt structure is picked up from the forming drum. The crossed belt structure is then toroidally shaped and transferred onto another forming drum. A zero degrees belt layer is then deposited on the other forming drum in a radially outer position with respect to the toroidally shaped crossed belt structure.

摘要： A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: arranging a first winding support with a first elongated element of a first type wound on the first winding support; arranging a second winding support with a second elongated element of a second type different from the elongated element of the first type wound on the second winding support; arranging a coupling device including a first coupling body and a second coupling body rotatable with respect to one another about a rotation axis; and arranging the first winding support on the first coupling body and the second winding support on the second coupling body.

摘要： A plant for building tyres for vehicle wheels includes a gripping ring arranged in a fixed reference position. A first stage building line defines a closed first-stage path for the movement of a plurality of building drums and an open first-stage path for building and moving carcass sleeves being processed. A second stage building line defines a closed second-stage path for the movement of a plurality of auxiliary drums and an open second-stage path for building and moving a plurality of outer sleeves being processed. The open second-stage path and the open first-stage path terminate at the gripping ring configured for carrying out a radially outer contrast function during the shaping of a first carcass sleeve being processed and the assembly thereof with a first outer sleeve being processed.

摘要： A plant for building tyres for vehicle wheels is described. The plant includes a crown structure building for building crown structures on second stage forming drums, a carcass structure building line for building carcass structures on first stage forming drums, a shaping and assembly station, a first manipulator, and a second manipulator. The first manipulator is configured to manage the flow of the second stage forming drums and the second manipulator is configured to manage the flow of the first stage forming terms.

摘要： A method for building tyres for vehicle wheels is described. Second stage forming drums are moved in a crown structure building line for building respective crown structures. Movement occurs along a first path for building a first part of components of the crown structure and a second path for building a second part of components of the crown structure. Additionally, first stage forming drums are moved in a carcass structure building line for building respective carcass structures. The flow of the second stage forming drums is managed through a first manipulator, while the flow of the first stage forming drums is managed through a second manipulator.
