The invention falls within the field of labeling machine with the continuous introduction of a reeled label film. In particular, it relates to the cutting roller of the label film and it comprises a cooling line for the two support systems of the shaft of the cutting roller. The cooling line is preferably independent for each of the two systems and it comprises a probe for measuring the temperature of the related support which sends its measured value to a block for its comparison with a pre-set preferential temperature value. The block, according to the compared value, activates a solenoid valve inserted on the compressed air supply circuit.
