Abstract: There is disclosed a method of manufacturing a plurality of removable permanently magnetized elements from a substrate comprising ferrite material. The method prints symbol images on the substrate with an offset, automatic sheet-fed press, and die cuts the symbol images on the substrate with an automatic sheet-fed die cutter to form a plurality of elements forming portions of the substrate. Thereafter, the method magnetizes the ferrite material to permanently magnetize the substrate and form the plurality of permanently magnetized elements. The method reduces wastage, permits for improved substrate registration, more accurate symbol placement on the substrate, higher production speeds, and reduced labor costs.

Abstract: There is disclosed a space planning assembly adapted to provide a human readable graphical furniture layout and a machine readable graphical furniture layout. The assembly has two-dimensional model furniture pieces scaled and shaped to represent the size of real furniture that adheres to the layout board by magnetic attraction. The furniture pieces each carry an invisible machine readable symbol which is scanned into a computer system to identify the actual furniture pieces, their relative location and orientation as represented by the model furniture pieces. The machine readable symbol has a central dot which identifies the location of the symbol, a radial line extending from the symbol to determine the angular orientation of the symbol and arc segments of concentric axial lines spaced radially outward of and at least partially encircling the central dot where the number of arc segments provide for a symbol identification number that represents a real furniture piece.
