Control method of tires or semi-finished products in tire production line, involves analyzing respective control signal on surface portion for detecting possible presence of surface flaws

NOVELTY - The control method involves detecting optical intensity of light radiation, calculating number of values representative equivalent number of components of strokes vector, and generating, for surface portion, a respective control signal representative of each value representative of components of Stokes vector. The respective control signal on surface portion is analyzed for detecting the possible presence of surface flaws. USE - Control method of tires or semi-finished products in tire production line. ADVANTAGE - Controls the quality of the tires or semi-finished products in production process, thus obtaining acceptable times and in a precise and reliable manner, a control of the surface of the tires or semi-finished products in production process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a control apparatus; and (2) a production line. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic block diagram of apparatus for controlling tires. Control apparatus (100) Semi-finished product or Tire (101) Support plane (120) Light source (131) Detection system (140) Processing unit (150)
