PROCEDURE FOR PRODUCING ENDLESS TAPE Enrollable SONORA explorable MECHANICALLY

摘要

Method of producing endless belts with several sound tracks mechanically scannable and parallel course or almost parallel to the edge of the tape by molding a limited matrix produced from an original sound endless belt (waxed tape etc); characterized in that the original sound tape or the matrix tape on either side are provided in the separation line to be transversely drawing the tape marks using a template being these marks also molded by making the multiplication of the tapes and putting the molded marks multiplied by the template tape again in the reciprocal position securing regulatory adjustment sound beam traces thereof in the two ends of the tape.
