Abstract: An apparatus for the treatment of an exterior pipe surface includes one or more nozzles or other treating means which are carried by a frame. The frame can be mounted around the pipe to be treated and is capable of moving along the pipe surface in longitudinal direction thereof, due to the provision of travelling wheels. Disclosed are provisions for allowing the apparatus to keep itself in balance on the pipe during operation. Such provisions include detection means (e.g. a pendulum with sensors) for detecting undesired displacements of the frame in circumferential direction of the pipe, and control means (such as e.g. hydraulic cylinders with a common system of hydraulic lines and valves) for adjusting the wheel axes of one or more travelling wheels in angular position, in response to a signal delivered by the detection means.

Abstract: The apparatus includes an elongate housing containing a rotatable plate-mounting drum, a reversibly rotatable brush roll, and first and second spray manifolds for respectively spraying fresh water and recirculated water onto the printing plates. The plate-mounting drum may be formed of perforate metal so as to facilitate mounting printing plates thereon. When the printing plate or plates to be cleaned extend longitudinally along only part of the plate-mounting drum, valves associated with the manifolds may be closed to cause water to be discharged only from those manifold sections that confront the printing plates. The fresh water supply circuitry of the apparatus is separate from the circuit for the recirculated water circuitry. A limit switch associated with a housing cover of the apparatus prevents discharge of water from the spray manifolds when the cover is not fully closed.
