ABSTRACT:
The invention is directed to a method of magnetically linking a ferromagnetic object to a partially magnetized coating material made by applying a coating to a surface of a continuously-moving medium including the steps of providing a coating material by mixing a binder material suitable for being spread substantially and regularly over the surface and a ferromagnetic component, the binder material being a hot melt adhesive; providing a continuously-moving medium having a top surface to be substantially coated, the surface capable of receiving a substantially and regularly spread coating material; passing the coating material and continuously-moving medium between rollers to form a substantially constant thickness of the coating material substantially covering the top surface and allowing the coating material to set to form the coated medium as a magnetizable component, wherein the medium that is coated is one of a paper, a card, wallpaper, a flexible plastic sheet, a rigid plastic sheet, and walls; partially magnetizing the coating material during continuous movement of the medium to create a magnetized area and an unmagnetized area; and magnetically and temporarily linking a ferromagnetic object to the magnetized area so that the coated medium and ferromagnetic object are held together by magnetic attraction.
