ABSTRACT:
A tubular sleeve (2) having a toothed inner surface (2a) is operatively mounted on rollers (12, 13) which rotate the sleeve (2) transversely to the extension of the teeth (5). photochromatic sensor (22) which is movable parallel to the rollers (12, 13) detects the presence of possible separation areas (9) between the sewn together end edges (6a, 6b) of a lining fabric (6) applied to the toothed surface (2a) of the sleeve (2), the end edges (6a, 6b) being chromatically differentiated from the elastomeric material (4) and from each other. An electronic processing unit (25) carries out the identification and storage of the position of the separation areas (9) detected by the photochromatic sensor (22). With the aid of a reading member (27) associated with the photochromatic sensor (22), the processing unit (25) identifies the position of the junction (7) between the end edges (6a, 6 b) on the extension outline of the toothed surface (2a), in order to detect and store the presence of possible anomalous positionings of the junction itself.
