Abstract:
A method for preparing an anti-theft paper roll, comprising:manufacturing a core onto which paper is wound to produce the paper roll, wherein the core is a hollow cylinder comprising an interior surface having a circular inside diameter and an exterior surface having a circular outside diameter, between which surfaces is a core wall, and wherein the exterior surface further comprises a longitudinal flat surface integrally formed therein; selecting an electronic sensor, wherein the sensor produces a detectable signal, and wherein the sensor comprises an upper surface and a lower surface, and wherein the dimensions of the sensor do not exceed the corresponding dimensions of the flat surface of the core; affixing the lower surface of the sensor to the flat portion of the exterior surface of the core, and wherein when the sensor is affixed to the core, the location of the upper surface of the sensor does not exceed the circular outside diameter dimension of the exterior surface of the core; selecting a solid loading rod of a paper winding machine, wherein the rod has an outside diameter less than the inside diameter of the core, and wherein the hollow core is loaded onto the loading rod through the hollow region of the core, to permit winding the paper onto the core when the paper winding machine is activated; and winding the paper onto the core with the sensor affixed thereto.
