ABSTRACT:
Installation for the automated manufacture of transmission belts, having equipment for the preparation of a multi-belt sleeve including at least one coiling machine (SP) on toothed drum, a calendering machine (CL1) for the application of a rubber composition, a molding and curing station (V1) and a final station (FN) having at least one checking machine (CQ) connected to a central control unit (UCC). The checking process is based on the use of a narrow range of tolerance wherein the values of the magnitude under control are acceptable, and of a wider range of tolerance external to the previous one, wherein the values of the magnitude are acceptable in a conditional manner, for example, in relation to the time of permanence within such range, and in any case after a final verification of the product affected by the anomaly.
