Abstract
According to the method of stripping a portion of a wire of the invention, the insulated wire including the wire core are first flattened before the insulation is stripped away. The flattening eases the stripping as the insulation is partially cracked and dissociated of the wire core, and the stripping is more efficiently applied on a flat surface. A wire stripping machine and a transponder antenna with stripped portions are also claim as being part of the invention.
Claims20
A wire antenna comprising:
- a. an inner metal core having a circular cross section;
- b. an insulation layer disposed around the core;
- c. the metal core and insulation layer having a length defining an axis;
- d. the metal core further comprising a flattened portion having a first flat outer surface and a second flat outer surface spaced from the first flat surface by a first dimension, and wherein the first and second flat outer surfaces each have a first edge and a second edge parallel with the wire axis, and a first curved surface interconnecting the first edges of the first and second flat outer surfaces and a second curved surface interconnecting the second edges of the first and second flat outer surfaces, and wherein the first curved surface is spaced from the second curved surface by a second dimension, and wherein the second dimension is at least twenty percent larger than the first dimension, and wherein the insulation layer is absent from at least a portion of the first flat outer portion.
