Title (EN) DEVICE FOR MONITORING METAL WIRES
(FR) DISPOSITIF DE CONTROLE DE FILS METALLIQUES
Abstract:
(EN) The invention relates to a device (18) for monitoring a reinforcement wire of a tyre (14), including: a member (68, 70) for inducing a magnetic flux (P1, P2; P) in the wire (42a-b; 100; 102), a generally U-shaped holder (67) holding the induction member (68, 70) and comprising arms (82, 84) for conducting the magnetic flux (P) in the wire (42a-b; 100; 102), the arms defining an alignment direction of the device, and at least one member (74) for receiving the magnetic flux (P1, P2; P) flowing in the wire (42a-b; 100; 102) located between the arms (82, 84). The receiving member is sized so as to measure only the magnetic flux flowing in the wire (42a-b; 100; 102), wherein the alignment direction (18) is parallel to the wire (42a-b; 100; 102) when in operation.
(FR) Le dispositif (18) de contrôle d'un fil de renfort d'un pneumatique (14) comprend : un organe d'induction (68, 70) d'un flux magnétique (P1, P2; P) dans le fil (42a-b; 100; 102), un support (67) portant l'organe d'induction (68, 70) présentant une forme générale en U et comportant des branches (82, 84) de conduction du flux magnétique (P) dans le fil (42a-b; 100; 102), les branches définissant une direction d'alignement du dispositif, au moins un organe de réception (74) du flux magnétique (P1, P2; P) circulant dans le fil (42a-b; 100; 102) situé entre les branches (82, 84). Les dimensions de l'organe de réception sont agencées de façon à mesurer seulement le flux magnétique circulant dans le fil (42a-b; 100; 102), lorsqu'en fonctionnement, la direction d'alignement (18) est parallèle au fil (42a-b; 100; 102).
