摘要：A method and apparatus to control manufacturing and feeding of semi-finishedproducts in a tyre building process, said method comprising: detecting at least a firstimage (A) representative of a semi-finished product (10) wherein said first image (A) isformed by a plurality of first portions (Al, A2), each one associated to a respectivebrightness value; defining a first threshold (THl) for said brightness values so that byarranging a first linear scale of the brightness values, defined between a first value (VI)corresponding to a null brightness value and a second value (V2) corresponding to amaximum brightness value, wherein the absolute value of the difference between saidfirst value (VI) and said second value (V2) defines an amplitude of said first scale, said firstthreshold (THl) is such that the absolute value of the difference between said firstthreshold (THl) and said first value (VI) is comprised between about 5% and about 20% ofthe amplitude of said first scale; performing a first comparison between the brightnessvalue of said first portions (Al, A2) and said first threshold (THl); as a function of said first
comparison, determining a first operating parameter (PI) representative of an overallarea occupied in said first image (A) by the first portions (Al) associated to a brightnessvalue higher or lower than said first threshold (THl); performing a second comparisonbetween said first operating parameter (PI) and a second threshold (TH2); if said firstoperating parameter (PI) is lower or higher than said second threshold (TH2), causing thegeneration of a first notification signal (NS1). An apparatus to control manufacturing andfeeding of semi-finished products in a tyre building process is also described.
