Abstract
An abrasive cleaning apparatus has an integral drum formed of inner and outer layers of resilient material and a rigid layer in between. Holes are formed through the drum in a spiral pattern around the drum. A wire is engaged in each hole, the wire having opposing ends and three bends. One end of the wire is inside the drum with an adjacent portion lying circumferentially on an inner surface of the drum. A portion of the wire outside the drum is aligned in an opposite circumferential direction as the portion of the wire inside the drum. A retaining cylinder sandwiches the end inside the drum between itself and an inside surface of the drum, holding the wire stable. The end of the wire inside the drum is in close proximity to ends of adjacent wires, which inhibits rotation of a wire in its hole in the drum.
