CA 2181960

The invention relates to a deactivatable security strip, as well as to a process and a facility for manufacture of a deactivatable security strip (1), particularly suitable for article surveillance in retail stores. The invention is based on the problem of proposing a security strip (1), which can be manufactured cost-effectively. The invention solves the problem by treating the semi-hard or hard magnetic strip (3), applying current to periodic consecutive sections (4b) of a specified length (b) a specified distance apart (a), in such a way that the remanent magnetisation component (M1r) parallel to the longitudinal axis (: = easy axis) of the semi-hard or hard magnetic strip (3) in the sections (4b) is less than the remanent magnetisation component (M0r) in the intervening, untreated sections (4a).
