Abstract
Method for checking the formation of beads of tyres including: arranging a carcass sleeve with formed beads with the carcass sleeve in rotation, acquiring at least an image of a circumferential portion of external surface including the respective edges of the end flaps turned up; processing the image in order to determine a circumferential trend of the axial distance of each edge from an axial reference plane; and detecting possible defects of the beads as a function of such trend.
Claims16
A method for checking the formation of beads of tyres in a tyre production line, the method comprising:
- arranging a carcass sleeve having end flaps turned up around respective annular anchoring structures in order to form respective beads;
- rotating said carcass sleeve around an axis thereof;
- during said rotation, acquiring at least one image representative of at least one circumferential portion of a radially external surface of said carcass sleeve, said at least one circumferential portion comprising respective edges of said end flaps turned up;
- processing said at least one image in order to determine a circumferential trend of an axial distance of each edge from a reference plane on said carcass sleeve orthogonal with said axis;
- and
- detecting possible defects of said beads as a function of said trend.
