Abstract:
1. A method of controlling the deposition of a plurality of semifinished elements for tyre production, comprising: sending a first radiation onto at least one component of a tyre being processed, said component being at least partly formed with said plurality of semifinished elements defining a radially external layer of said tyre being processed, said semifinished elements being strip-like elements distinct from each other and suitably disposed in side-by-side or partially overlapped relationship, said strip-like elements being laid axially on a forming support; receiving a corresponding first reflected radiation from a radially external surface of said tyre being processed; determining, as a function of at least said first reflected radiation, one or more parameters representative of a thickness of said radially external layer; wherein said one or more parameters comprise a first parameter representative of mutual overlapping of said semifinished elements and a second parameter representative of a lack of mutual overlapping of said semifinished elements, wherein determining said one or more parameters comprises: comparing said one or more parameters with corresponding reference values; and generating an alarm signal as a function of said comparison, wherein the alarm signal is generated if the first parameter is greater than a first reference value or if the second parameter is greater than a second reference value, each of the first reference value and the second reference value being representative of a distance equal to at least ⅓ of a width of one of said semifinished elements measured along a circumferential extension of said forming support.
