Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
A magnetic anchoring device for graphic arts, wherein the magnetic work surface is provided by permanent magnetic cores interposed between ferromagnetic material pole-pieces, having a direction of magnetization for the cores substantially at right angles to said pole-pieces, characterised by comprising a support of ferromagnetic material having a plurality of parallel slots separated by walls defining a first plurality of pole pieces fast with said support; a spacer of non-magnetic material positioned in each of said slots, and each of said slots having therein a permanent magnet battery means comprising an inserted central core means of ferromagnetic material which is interposed between two side permanent magnetic elements, the assembly of said inserted walls defining a second plurality of pole-pieces alternately interposed to the first plurality of pole-pieces; the surfaces of the magnetic elements contacting each of said inserted walls having always the same polarity, so that the magnetic surface has pole-pieces of one polarity intercalated with pole-pieces of opposite polarity to said one polarity.
Claim 2
Dependent Claim
164 words
A magnetic anchoring device for graphic arts, wherein the magnetic work surface is provided by permanent magnetic cores interposed between ferromagnetic material pole-pieces, having a direction of magnetization for the cores substantially at right angles to said pole-pieces, characterised by comprising a support of ferromagnetic material having a plurality of parallel slots separated by walls defining a first plurality of pole pieces fast with said support; a spacer of non-magnetic material positioned in each of said slots, and each of said slots having therein a permanent magnet battery means comprising an inserted central core means of ferromagnetic material which is interposed between two side permanent magnetic elements, the assembly of said inserted walls defining a second plurality of pole-pieces alternately interposed to the first plurality of pole-pieces; the surfaces of the magnetic elements contacting each of said inserted walls having always the same polarity, so that the magnetic surface has pole-pieces of one polarity intercalated with pole-pieces of opposite polarity to said one polarity.
