ABSTRACT:
A process and apparatus for identifying defects within the structure of a tubular sleeve used to make toothed belts, the sleeve, having a toothed inner surface 2a, is operatively mounted on rollers 5, 6 operable in rotation to move the sleeve transversely to the extension of the teeth 3. An ultrasonic emitting and receiving member 15 movable parallel to the rollers 5, 6 detects the presence of structural cavities 3a in the sleeve. An electronic processing unit 20 carries out the identification and memorization of the position of the structural cavities 3a on the longitudinal extension of the sleeve 2.
