An abrading apparatus for cleaning an outer surface of an elongate member, such as a wire. An endless abrasive sanding belt is rotated about a plurality of rollers and orbited about the elongate member. Drive components for both rotating the belt about the rollers as well as orbiting the belt about the elongate member are isolated in an enclosed drive casing containing lubricating fluid, such as oil. A first roller which mounts the endless sanding belt is fixed in a rotatable eccentric support. This eccentric support allows the tension of the endless belt to be adjusted by rotating the eccentric support in one of two directions. One of the rollers includes a mounting portion and a belt supporting portion, with the mounting portion being axially offset or eccentric with respect to the belt supporting portion. A belt engagement and disengagement mechanism is connected to the eccentric mounting portion of the idler roller to allow rotation of the eccentric mounting portion in two directions. |
