ABSTRACT:
A pipe having a guide pattern or template mounted on and surrounding it is rotatable about its longitudinal axis while a pattern follower actuates a cutting or welding tool to move longitudinally as the pipe rotates. The follower and tool are carried by a frame supported on the pipe by rollers. The frame is mounted on a support for universal tilting and for horizontal sliding in one direction to ensure that the follower and tool bear a constant relationship to the pipe irrespective of any undulations or out-of-round features of the pipe.
