Process and device for magnetically checking worn tires
First Claim
1. A process for the non-destructive verification of the condition of a metallic reinforcement element of magnetic material in a worn tire, comprising the steps of:
- subjecting said metallic reinforcement element to a magnetic field in order to magnetize it;
creating a relative movement between said metallic reinforcement element of said tire and at least one conductor of a detection device placed opposite said metallic reinforcement element in such a manner that any variation in magnetization of said element induces an electromotive force in said conductor;
detecting and recording said electromotive force for the whole of said metallic reinforcement element;
determining at least one magnitude characteristic of the whole of the recorded values of said electromotive forces; and
comparing said characteristic magnitude with at lest one reference magnitude in order to determine the condition of said metallic reinforcement element in said worn tire.

Abstract
A process and apparatus for the non-destructive checking of the condition of a metal reinforcement element of magnetic material in a tire (11) wherein
the metallic reinforcement element is subjected to a magnetic field in order to magnetize it;
relative movement is produced between the metallic reinforcement element of the tire (11) and at least one conductor (31) of a detecting device (30) placed opposite the metallic reinforcement element in such a manner than any variation in magnetization of the element produces an electromotive force in the conductor (31);
the electromotive force is detected in order to obtain information as to the condition of said magnetized metallic reinforcement element.
