摘要： A method for verifying the correct formation of the beads in a process and a plant for building tyres for vehicle wheels, includes: loading a plurality of annular anchoring structures in a storage, disposing them in two groups separated by an opening; positioning a building drum provided with a carcass sleeve in a tyre bead-forming machine; picking up two of the annular anchoring structures from the storage and loading them on the tyre bead-forming machine. In a work area of the tyre bead-forming machine, on each of two axially opposite zones of the carcass sleeve, a respective annular anchoring structure is fit and each of the abovementioned zones is turned up around the respective annular anchoring structure to form the beads. The aforesaid opening allows an operator to conduct a visual inspection of the work area and/or access the work area during the entire work cycle of the machine.

摘要： A process for manufacturing tyres for vehicle wheels, comprising the step of building on a forming support a carcass structure comprising at least one carcass ply and, at least one end edge of the carcass ply, at least one annular anchoring structure comprising at least one substantially circumferential annular insert and at least one filling insert associated to said at least one substantially circumferential annular insert. The step of building the carcass structure comprises the steps of positioning the annular anchoring structure on the carcass ply by moving the annular substantially circumferential insert into contact with an end edge of the carcass ply by means of a special positioning member, pulling down the filling insert on the end edge of the carcass ply and turning up a free end portion of the end edge of the carcass ply so as to form a turned up end portion of the carcass ply including said annular anchoring structure. The pulling down of the filling insert on the end edge of the carcass ply is carried out by a special pulling down member while the substantially circumferential annular insert is retained into a contact position with the end edge of the carcass ply by said positioning member.

摘要： A method and a device for the production of a green tire, in which at least two materials in strip form are positioned on a tire building drum. At least two cores are set in place. The tire building drum is equipped both with a core clamping device and with a core fixing device. The tire building drum is composed of a central part and of two drum halves arranged adjacent to the central part on both sides. The drum halves are arranged such that they can be positioned in an axial direction. The central part is equipped with a variable diameter in a radial direction. A radial enlargement of the diameter of the central part is performed before the cores are set in place.

摘要： In a process for building tyres for vehicle wheels, a carcass sleeve is arranged on a shaping drum including two half-drums and two supports. Each support is operatively associated with one of the half-drums and carries a plurality of turning-up levers having free ends positioned close to the respective half-drum. Two annular anchoring structures are disposed around the carcass sleeve and each of the two supports is locked to the respective half-drum by interposing only stiff mechanical elements in mutual contact between the support and the half-drum. The carcass sleeve is shaped in a toroidal conformation, by setting a threaded shaft in rotation and moving the half-drums close to each other. Subsequently, each of the two supports is unlocked from the respective half-drum and the threaded shaft is set in rotation to move each support close to the respective half-drum and lift up the free ends of the turning-up levers until the end flaps of the carcass sleeve are turned up around the annular anchoring structures.
