Abstract
A system for assembling a novelty button having a magnet inserted between the back cover and the front plate includes a first rotary table of a non-ferrous material having one or more receiving cups. Each receiving cup is sized to receive one magnet from a vertical stack of magnets. A stationary, non-ferrous shearing removes a bottommost magnet from the stack when the first table rotates. A second rotary table made from a non-ferrous material having at least one non-ferrous lower die fixture receives a subassembly consisting of a back cover and a magnet arranged on interior face of the back cover. A modified button press having a non-ferrous upper die set crimps a front plate to the back cover.
