An apparatus for refurbishing a belt, the latter having a width, a length and a degraded surface. The apparatus includes a frame, a grinding roller for selectively and uniformly removing a determined amount of the degraded surface along the belt width, and a positioning member to keep the belt in position during refurbishment, both the roller and the positioning member are mounted on the frame adjacent to each other. The grinding roller defines a helical grinding region thereof and a substantially complementary helical non-grinding region thereof. The positioning member has a belt abutment member spacedly positioned relative to the grinding roller to abuttingly retain the belt against the roller and a belt tensioning member to tension the belt in either side of the roller in the displacement direction of the belt. The apparatus, when not used as a kit onto an existing belt conveying machine, also includes a motor secured to the frame to selectively displace the belt relative to the grinding roller along the belt length. |
