PROCESS AND PLANT FOR BUILDING GREEN TYRES FOR VEHICLE WHEELS.

摘要

There are described a plant and a process for building green tyres for vehicle wheels, said process comprising the steps of: a) building a carcass structure on a first forming drum (6) in at least one carcass structure building line (2) comprising a plurality of work stations arranged according to a sequential series, said carcass structure comprising at least one carcass ply and a pair of annular anchoring structures; b) building a crown structure on at least one second forming drum (7) in at least one crown structure building line (3) comprising a plurality of work stations arranged according to a sequential series, said crown structure comprising at least one belt structure; c) toroidally shaping said carcass structure assembling it to said crown structure in at least one shaping and assembling work station (4) for the tyre being processed; wherein the transfers of each of said first forming drum (6) and said second forming drum (J), with the respective carcass structure and crown structure being processed, from one work station to the other of the respective building lines (2, 3) comprise at least one step d) of transfer from a first work station to a second work station not adjacent to the first one in said 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 (7) only pass in said first and second work station. Method for reconstruction of a three-dimensional model of an osteo-articular structure of a patient, wherein a) bi- dimensional patient-specific image data (41) of said structure is provided; (d) a preliminary solution, corresponding to a previously established solution model of the structure, is provided (42) from a base (21), said preliminary solution comprising a priori knowledge of the corresponding structure, previously established from structures of the same type, said preliminary solution comprising surface data describing the coordinates of the surface of the solution model, and bulk data describing at least one characteristic of the inside of the solution model; the preliminary solution is modified (42', 43, 44, 46, 47, 48) to be brought in concordance with said patient-specific image data. There are described a plant and a process for building green tyres for vehicle wheels, said process comprising the steps of: a) building a carcass structure on a first forming drum (6) in at least one carcass structure building line (2) comprising a plurality of work stations arranged according to a sequential series, said carcass structure comprising at least one carcass ply and a pair of annular anchoring structures; b) building a crown structure on at least one second forming drum (7) in at least one crown structure building line (3) comprising a plurality of work stations arranged according to a sequential series, said crown structure comprising at least one belt structure; c) toroidally shaping said carcass structure assembling it to said crown structure in at least one shaping and assembling work station (4) for the tyre being processed; wherein the transfers of each of said first forming drum (6) and said second forming drum (J), with the respective carcass structure and crown structure being processed, from one work station to the other of the respective building lines (2, 3) comprise at least one step d) of transfer from a first work station to a second work station not adjacent to the first one in said 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 (7) only pass in said first and second work station.
