Disclosed is a pipe wrapper and cleaner or similar apparatus which includes a rotatable drum with an axial linear slot or gap therein which may be supported on and rotated about an elongated body such as a pipe by casters carried by the drum and engaging the elongated body to support the drum concentrically thereabout. An outwardly projecting flange encircles the drum with a gap therein coincident with the gap in the drum. The drum is rotated by a pair of drive gears powered by synchronous motors and placed circumferentially apart by an arcuate distance greater than the arcuate length of the gap in the flange.
