Process and apparatus for the magnetization of magnetizable materials

Abstract:

An apparatus and method for magnetizing a magnetizable ink. The apparatus can include a first pair of first and second cylindrical magnetic arrays defining a first gap. The first and second cylindrical magnetic arrays can each have alternately spaced magnetized sections that are spaced apart axially by flux conducting elements. The apparatus can include a second pair of third and fourth cylindrical magnetic arrays defining a second gap. The third and fourth cylindrical magnetic arrays can each have alternately spaced magnetized sections that are spaced apart axially by flux conducting elements. The apparatus can include a third pair of fifth and sixth cylindrical magnetic arrays defining a third gap. The fifth and sixth magnetic array can have alternately spaced magnetized sections that are spaced apart axially by flux conducting elements. The cylindrical magnetic arrays can be positioned to receive a moving web substrate through the first, second, and third gaps.
