Abstract:
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; and d) feeding pairs of second annular anchoring structures from the first storage region to the bead-forming machine. The method includes the sequential cyclic repetition of the above actions.
Abstract:
A plant and a process for building green tyres for vehicle wheels. The process includes: a) building a carcass structure on a first forming drum in at least one carcass structure building line including a plurality of work stations arranged according to a sequential series, the carcass structure including at least one carcass ply and a pair of annular anchoring structures; b) building a crown structure on at least one second forming drum in at least one crown structure building line including a plurality of work stations arranged according to a sequential series, the crown structure including at least one belt structure; c) toroidally shaping the carcass structure assembling it to the crown structure in at least one shaping and assembling work station, wherein the transfers of each of the first forming drum and the second forming drum, with the respective carcass structure and crown structure being processed, from one work station to the other of the respective building lines includes at least one transfer from a first work station to a second work station not adjacent to the first one in the sequential series, and wherein each step d) of transfer takes place in such a way that the first forming drum and the second forming drum only pass in the first and second work station.

Abstract:
A plant, a method and a process for building tyres for vehicle wheels in a carcass structure building line includes: a) associating a pair of support rings with a forming drum in a work station for associating support rings; b) building at least one structural component of the tyre being processed on the forming drum provided with the pair of support rings in at least one work station of the carcass structure building line; c) removing the pair of support rings from the forming drum in a work station for removing support rings; d) transferring the pair of support rings dissociated from the forming drum to a temporary storage for support rings; and e) building at least one further structural component of the tyre being processed on the forming drum without the pair of support rings in a work station of the carcass structure building line.
