Method and apparatus for controlling production and feeding of semifinished products in a tyre building process

An apparatus to control manufacturing and feeding of semifinished products in a tyre building process, comprising:

• at least one first detection device for detecting at least one first image representative of a semifinished product;
• at least one first memory;
• at least one first processing unit associated with said first detection device and with said first memory, and configured for:
• i. dividing said at least one first image into a plurality of first sub-parts, wherein each one of said first sub-parts is formed by a plurality of first portions, each first portion associated with a respective brightness value;
• ii. making a first comparison between brightness values of said first portions and a first threshold stored in said first memory and concerning said brightness values;
• iii. as a function of said first comparison, determining for each one of said first sub-parts a first operative parameter representative of a total area occupied in each first sub-part by the first portions associated with a brightness value smaller or greater than said first threshold;
• iv. making a second comparison between each one of said first operative parameters and a second threshold;
• and
• v. causing generation of a first notification signal as a function of said second comparison;
• and
• a first background wall positioned on an opposite side of said semifinished product with respect to said first detection device.
