A plant for building tyres includes a plurality of working locations, at least one first working location being associated with at least two loading/unloading locations, a proximal one and a distal one, each of said working locations and loading/unloading locations being associable with a forming drum. The production cycle is controlled by the method of: (i) loading a first forming drum into the at least one first working location; (ii) loading a second forming drum into the loading/unloading location; (iii) at the end of the working provided in the at least one first working location, unloading the first forming drum into the proximal loading/unloading location.

In an assembly station a carcass sleeve and an outer sleeve manufactured along respective building ones are mutually coupled. Integrated into the assembly station are engagement devices that can be alternatively coupled to an auxiliary drum carrying an outer sleeve and to a building drum carrying a carcass sleeve. A grip unit picks up the outer sleeve from the auxiliary drum associated with the engagement devices in order to position it to a location radially external to the carcass sleeve carried by the building drum associated with the engagement devices in place of the auxiliary drum. Shaping devices that can be operatively coupled to the building drum cause radial expansion of the carcass sleeve so as to enable the latter to be coupled to the outer sleeve retained by the grip unit.

The tire management method is a method of managing a tire group including a plurality of tires 1 on each of which a first mark M1 and a second mark M2 are provided on specific positions of a side surface, the method including: a step of associating, with respect to each of the tires included in the tire group, specific information of the tire and mark positional information (12, r1, and r2) related to positions of the marks M1 and M2, and recording these into a computer 2; a step of acquiring mark positional information of a tire selected from the tire group; and a step of acquiring, by using the computer 2, specific information associated with the previously-acquired mark positional information.

A plant and a process for producing tyres for vehicle wheels, includes the steps of: a) building a carcass structure of a green tyre on a first forming drum in at least one carcass structure building line, the carcass structure including at least one carcass ply and a pair of annular anchoring structures; b) building a crown structure of a green tyre on at least one second forming drum in at least one crown structure building line, the crown structure including at least one belt structure and a tread band; c) toroidally shaping the carcass structure assembling it to the crown structure in at least one assembling and shaping work station for the tyre being processed, the assembling and shaping work station being synchronized with the carcass structure building line and with the crown structure building line; wherein each carcass structure is associated with the respective first forming drum whereon it is built up to the end of step c) of shaping and assembling the tyre being processed; and d) moulding and vulcanizing the green shaped tyre in at least one tyre moulding and vulcanizing line separate from said assembling and shaping work station.

In order to make a tire factory more compact, this tire manufacturing system comprises a material storage zone, a green tire formation zone, a vulcanization zone, and an inspection and discharge zone. The green tire formation zone has a track and a plurality of work stations arranged along the track, where a green tire is formed by assembling a tire constituent member to an outer surface of a rigid core moving on the track at each of the work stations. A member assembly device that forms the tire constituent member by attaching a member material set for each of the tire constituent members to a surface of the rigid core, under an attachment condition determined according to size of the rigid core. The member assembly devices being arranged at an outer peripheral side of the square-cornered U-shaped bending track and along the lateral track parts. The material storage zone is arranged adjacent to one lateral side of the square-cornered U-shaped bending track. The vulcanization zone is arranged adjacent to the other lateral side of the square-cornered U-shaped bending track. The inspection and discharge zone is arranged adjacent to the other lateral side of the vulcanization zone.

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.

Method and plant for producing tyres for vehicle wheels in which: each vulcanizer (30) of a plurality of vulcanizers (30) is associated with a respective pick-up logic of green tyres from at least one storage area (20) of green tyres; upon each request to vulcanize a green tyre in a vulcanizer (30) of the plurality of vulcanizers (30), the pick-up logic associated with said vulcanizer (30) is applied to select and pick up a green tyre from the storage area (20); the respective pick-up logic associated with each vulcanizer (30) comprises a first pick-up rule of green tyres from the storage area (20) and, for at least one of the plurality of vulcanizers (30), the first pick-up rule is changed into at least one second pick-up rule at least once during the production in the plant (1) of at least one lot of tyres.

A method for managing a carcass structure building line, a plant and a process for building tyre carcass structures, wherein the plant includes a carcass structure building line provided with a plurality of stations including an unloading station and n building stations. A group of forming drums being processed includes m forming drums being processed defining a first size of carcass structure being processed. Three groups of entering forming drums include respective entering forming drums, defining a second size of carcass structure being processed. A pair of support elements being processed includes a first and a second support element being processed and three pairs of entering support elements respectively include a first and a second entering support element. The invention also relates to a method for managing a carcass structure building line.

A system manufactures a tire assembly. The system includes a core having a cylindrical hub and radially protruding extensions projecting radially outward from the hub, a plurality of internal arcuate members for positioning a reinforcing layer of the tire assembly about the core, the internal arcuate members being disposed in spaces between the extensions of the core, a first side plate for securing the internal arcuate members in place relative to the core, and a second side plate for securing the core and internal arcuate members to each other.

A system to manufacture a tire includes one or more processors and one or more memories storing instructions executable by the one or more processors and causing the one or more processors to receive, from one or more sensors of one or more pieces of tire manufacturing equipment, one or more values corresponding to manufacturing of a tire, generate a matrix based on the one or more values, predict, via input of the matrix into a machine learning model, a value for a splice tolerance metric for the tire, determine, based on the value for the splice tolerance metric, a first parameter of a first piece of the one or more pieces of tire manufacturing equipment to adjust, and provide a command to adjust the first parameter of the first piece of equipment responsive to determining the value of the splice tolerance metric.
