ABSTRACT:
In that a method for bar code marking on vulcanizable or vulcanized rubber products, where the bar code of each marking varies from the preceding one, a bar code pattern (4) is given to the rubber product (2) through a source of electromagnetic radiation which is controlled by a computer electronic word processing system to form the bar code pattern (4) required on the rubber product (2) surface, i.e., the first side (12) and focusing on this, and that the source of radiation wavelengths and energy are adapted to the kind of marking and marking (4) depth required in the rubber product (2), higher bar code wearability is achieved.
