ABSTRACT:
A method for making conductive brushes which comprises providing a rotatable cylindrical mandrel having a plurality of longitudinal recesses on its surface, and winding electrically conductive fibers from a supply around the mandrel by rotating the mandrel. The brush backing or base may be formed by a number of methods utilizing the recesses on the surface of the mandrel. In one embodiment, the brush backing is formed by placing a strip of a conductive material in each of the recesses, and after the conductive fibers have been wound thereover, the conductive fiber windings are caused to adhere to each other by adhesive means and another strip of conductive material is placed over the windings to mate with the strip in the recess to form the backing for the conductive brush. Individual conductive brushes are obtained by cutting the conductive fibers in the longitudinal direction of the mandrel. Other embodiments of the method for producing the backing or base of the conductive brushes, including one embodiment in which a mandrel without recesses is used, are also disclosed.
