<p>PURPOSE:To increase the amount of information to be written by using a system in which discriminating codes are magnetically written in a magnetic elastomer part previously mixed with a magnetic powder in a method of discriminating manufacture data for tire. CONSTITUTION:A thin rubber sheet 5 previously mixed with a magnetic powder is bonded with the tread 2 or side wall 3 of a tire 1 and integrally combined by vulcanization. In the molding process, the vulcanizing process, and the finishing process, discriminating codes of molding data, vulcanization date, etc., set by a data setting board 9 are written magnetically in the magnetic portion 6 of the tire 1 being turned through a signal processing circuit 10 and a head drive circuit 11 by means of a head 7. The reading of the discriminating codes is displayed on a data display board 14 through a head 12, an amplifier 16, and a signal processing circuit 15. Since a wide range of writting section can be provided, the amount of information to be written can be greatly increased without the need for high positioning accuracy and also without causing discoloration and delamination.</p> |
