Abstract: A method for controlling the manufacturing of tires for wheels of vehicles includes: extracting a cured tire from a curing station, in which the cured tire has accumulated heat during a curing process; and verifying the presence of possible defects or imperfections in that cured tire. The verification includes detecting first electromagnetic radiations representative of a heat emission from different portions of the cured tire while the cured tire frees the accumulated heat; providing at least one output signal representative of the first electromagnetic radiations detected to allow an analysis of the cured tire and to verify the presence of the possible defects or imperfections. A plant for the manufacturing of tires for wheels of vehicles is also described.

Abstract: A method and apparatus for checking tyres in a tyre production line. The method includes alternately illuminating, with a first and second grazing light radiation, a surface portion of the tyre and respectively acquiring a first and second two-dimensional digital image of the illuminated surface portion. For each point of the surface portion, the respective overall light power of the first and second light radiation incident at the point respectively comes from two half-spaces that are opposite with respect to an optical plane passing through the perpendicular to the surface at the point; and comparing the first and second image to obtain information on an altimetric profile of the surface portion.
