ABSTRACT:
A device for cutting a metal or plastic jacket which surrounds a layer of foam on an insulated pipe is the subject of the present invention. A circumferential track mounts on the jacket and a ring gear is movable in the track. The cutting means is mounted on the ring gear for movement therewith. The cutting means is pivotally mounted so that it may assume a first position out of cutting engagement. Even in its non-cutting position, however, the leading edge of the cutting means will contact the jacket and movement in a circumferential direction will cause the cutting edge to penetrate the jacket and urge it into its cutting position. A motor is provided to drive the ring gear and cutting means around the track.
