摘要:
A method of controlling the deposition of semifinished elements for tire production, includes: sending a first radiation onto one tire being processed, consisting of one forming support with at least one portion of the tire component laid on the support, the tire component being at least partly formed of a plurality of semifinished elements defining a radially external layer of the tire being processed; receiving a first reflected radiation from a radially external surface of the tire being processed; determining, as a function of the reflected radiation, parameters representative of the thickness of the layer; comparing the parameters with reference values; and generating an alarm signal as a function of the comparison.

A method of controlling the deposition of semifinished elements for tyre production, includes: sending a first radiation onto one tyre being processed, consisting of one forming support with at least one portion of the tyre component laid on the support, the tyre component being at least partly formed of a plurality of semifinished elements defining a radially external layer of the tyre being processed; receiving a first reflected radiation from a radially external surface of the tyre being processed; determining, as a function of the reflected radiation, parameters representative of the thickness of the layer; comparing the parameters with reference values; and generating an alarm signal as a function of the comparison.

A process and an apparatus for building tyres for vehicle wheels includes assembling at least one tyre component through laying of strip-like elements disposed circumferentially close to each other on a deposition surface radially external to the forming drum, wherein laying of each strip-like element includes: radially moving the strip-like element close to the deposition surface; locking a central portion of the strip-like element against the deposition surface; and pulling the strip-like element in opposite directions starting from the central portion toward the opposite ends thereof, while the central portion is maintained in a locked condition against the deposition surface, so as to progressively lay down the strip-like element against the deposition surface.

In an assembly station, a carcass sleeve and an outer sleeve manufactured along respective building lines 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. The building drum is engaged on the assembly station before removal of the auxiliary drum. A grip unit picks up the outer sleeve from the auxiliary drum associated with the engagement devices in order to position it around the carcass sleeve carried by the building drum.

摘要:
A method of controlling the management of forming drums in building tyres for vehicle wheels and a plant for production of tyres for vehicle wheels, wherein the plant includes at least one building line including at least one assembly of “m” work stations, each adapted to form at least one portion of a component of the tyre; devices for feeding and picking up “n” forming drums, one at a time, to and from the building line at each time interval equal to a cycle time; transfer devices for respectively bringing and moving apart “m” distinct forming drums to and from “m” distinct work stations of the assembly, wherein each of the “m” work stations respectively receives and releases a forming drum at each time interval equal to a multiple of “m” of said cycle time, wherein “m” is greater than or equal to 2 and “n” is greater than or equal to “m”.
