ABSTRACT:
A marker device for merchandise items has blanks of high magnetic coercivity material spaced along a strip of high magnetic permeability material. The strip and blanks are the same width, produced from three ribbons of material, one ribbon of the high coercivity material, another of the high permeability material, and a third having a pressure sensitive adhesive surface in one process embodiment, and the third being a heat activated adhesive film in another process embodiment. The strip and blanks are thereby adhesively connected. Multiple strips of the marker devices are produced simultaneously by running adhesively connected ribbons through a gang of slitter knives.
