Abstract (en)
[origin: WO8503461A1] A method of inducing back tension in a longitudinally moving magnetiseable strip (6) comprising the steps of positioning a stationary electro-magnet (5) adjacent to one side of the strip (6), interposing a layer of fabric or other friction material (8) between the magnet (5) and the strip (6) and energising the magnet (5) to effect drag on the strip (6) due to pressure contact between the strip (6) and the layer (8). Also disclosed is a drag pad comprising an electro-magnet (5) providing an array of closely spaced, mutually parallel, elongate pole faces (19, 20) each of opposite polarity to its neighbouring face or faces and a layer of friction material (8) covering the array.
