A method for managing the production cycle of a plant for building tyres for vehicle wheels, wherein the plant provides for a storage region (11) for anchoring annular structures (6) and a plurality of processing stations (10) at least one of which is associated with a forming drum (13), comprises feeding a plurality of anchoring annular structures (6) to the storage region (11), picking up the anchoring annular structures (6) from the storage region (11) at a predetermined picking-up position that does not change on changing of the types of the anchoring annular structures (6), feeding the picked-up anchoring annular structures (6) to the processing station (10) associated with the forming drum (13).

A bead wrapping system for wrapping a strip around a tire bead may include one or more of the following components: an expandable chuck, a strip handling system, and a former assembly. At least one of the strip handling system and the former assembly may be movable radially relative to a central gear of the expandable chuck in response to rotation of the central gear.

A method of controlling the management of annular anchoring structures in a process and a plant for building tyres for vehicle wheels includes a) feeding pairs of first annular anchoring structures from a first storage region to a bead-forming machine; b) loading a plurality of second annular anchoring structures into a second storage region; c) carrying the second annular anchoring structures from the second storage region to the first storage region; d) feeding pairs of second annular anchoring structures from the first storage region to the bead-forming machine; e) loading a plurality of first annular anchoring structures into said second storage region; and f) carrying the first annular anchoring structures from the second storage region to the first storage region.

An apparatus (10) for producing green tyres (13) consisting of a carcass or inner section (13) coupled with a belt package or outer section (13), comprising a first tyre processing assembly (12) for manufacturing the carcass or inner section (13), a second tyre processing assembly (14) for finishing said carcass (13), a third tyre processing assembly (16) for manufacturing a belt package or outer section (13) and for coupling said carcass or inner section with said belt package or outer section (13, 13) to form a tyre (13), and an unloading station (60) for unloading said tyre (13), said tyre processing assemblies comprising interface means for transferring the product being manufactured from one tyre processing assembly to another one and for moving said product being processed internally to said individual tyre processing assemblies in a fully automatic manner.

A method and a plant for managing the production cycle of a plant for building tires for vehicle wheels, wherein the plant provides for a storage region for anchoring annular structures and a plurality of processing stations at least one of which is associated with a forming drum, includes feeding a plurality of anchoring annular structures to the storage region, picking up the anchoring annular structures from the storage region at a predetermined picking-up position that does not change on changing of the types of the anchoring annular structures, and feeding the picked-up anchoring annular structures to the processing station associated with the forming drum.

A bead-apex assembly system comprising a bead forming system and an apex application system. In one embodiment, a supporting assembly is located at least partially between the bead forming system and the apex application system, and the supporting assembly is adapted to move an annular bead ring from the bead forming system to the apex application system.

Disclosed is a filler-raising device that raises a filler upright to couple the filler with a bead core. The filler-raising device includes a balloon that raises the filler upright toward the bead core and an air controller that supplies air into the balloon and draws air out of the balloon.

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.

A system for handling a bead apex includes a first jaw having open and closed states, which is configured to engage a first surface of a bead apex in the closed state. The system further includes a second jaw having open and closed states, and a plurality of grippers coupled to the second jaw, wherein each of the plurality of grippers comprises a body. At least one of the plurality of grippers includes a pivot shoe rotatably attached to the body of the at least one of the plurality of grippers, wherein the pivot shoe is rotatable with respect to the body of the at least one of the plurality of grippers. The pivot shoe is configured to engage a second surface of the bead apex in the closed state of the second jaw.

A plant (1) for looping annular anchoring structures (100) includes a looping device (2), a separation station (8a) and a coupling station (8b). A handling apparatus (3) is interlocked to the looping device (2) for managing the plant (1) by moving the plurality of annular anchoring structures (100) coupled to respective separation elements (300), the looped annular anchoring structures (200) coupled to respective separation elements (300) and the separation elements (300a). The separation elements (300) are fed, coupled to respective annular anchoring structures (100), along a feeding section (A1). The separation elements (300a) separated by respective annular anchoring structures (100, 200) are transferred from the separation station (8a) to the coupling station (8b) along a transfer section (T), stationing in at least a first intermediate station (11, 11a). The separation elements (300) are moved away, coupled to respective looped annular anchoring structures (200), along a moving-apart section (A2).
