Abstract
A magnetic means for centering a flexible elongated mandrel within a vertical passage (chute) without any physical connection between the mandrel and the passage surface. The mandrel carries a tapered nose piece that includes an elongated magnetized rod. An array of cooperating magnets is arranged around the perimeter of the passage, so that the magnetic circuits of the rod and perimeter magnets interact to produce a radial repulsion of the rod to a position on the passage axis.
