A longitudinal curvature in an amorphous metal alloy ribbon is reduced by heat-treatment. While the heat-treatment occurs, the alloy ribbon is bent "backwards" against the longitudinal curvature, to reduce the amount of heat-treatment required. The process is carried out continuously by transporting the alloy ribbon from reel to reel, while wrapping the ribbon around a heated roller. Using a discrete strip cut from the alloy ribbon subjected to the curvature-reducing process, a magnetomechanical EAS marker is constructed that has a relatively low profile, while retaining desired magnetic properties. |
