Abstract

L'invention concerne un procédé et un dispositif permettant de produire des éléments antivol (1) désactivables destinés à la protection électronique des articles. Selon ce procédé, on utilise une bande (2) de matériau magnétique doux de longueur donnée, excitée par application d'un champ magnétique alternatif afin d'émettre un signal caractéristique, et des sections (3) de longueur donnée d'un matériau magnétique dur ou semi-dur. Les sections (3) sont disposées par rapport à la bande de matériau magnétique doux de manière, lorsqu'elles sont à l'état de saturation, à faire cesser le signal caractéristique émis par la bande de matériau magnétique doux (2). L'invention a pour objet de proposer un procédé et un dispositif permettant la production économique des éléments antivol désactivables. Pour ce faire, une bande continue (4) de matériau magnétique dur ou semi-dur est subdivisée en sections (3) de longueur donnée. Ces sections (3) sont acheminées au moyen d'un dispositif de transport (7) à une vitesse supérieure à celle de la bande continue (4). La vitesse relative est calculée de manière à obtenir la distance voulue entre deux sections (3) successives et à relier une bande continue (15) de matériau magnétique doux aux sections (3) de matériau magnétique dur ou semi-dur, qui sont espacées.
