Zusammenfassung:	THERE IS DISCLOSED AN APPARATUS FOR WORKING A SURFACE OF A METAL PIPE (10). THE APPARATUS INCLUDES A WORKING ASSEMBLY (18) FOR WORKING THE METAL PIPE (10) TO FORM AN INNER SURFACE AND/OR AN OUTER SURFACE THEREOF INTO PREDETERMINED CONFIGURATION. THE WORKING ASSEMBLY (18) INCLUDES A PLURALITY OF ROLLING ROLLS (31) ROTATABLY DISPOSED AROUND THE METAL PIPE (10) SO THAT THEY CAN REVOLVE AROUND THE METAL PIPE (10). EACH OF THE ROLLING ROLLS (31) HAS AN AXIS INCLINED WITH RESPECT TO AN AXIS OF THE METAL PIPE (10) IN SUCH A DIRECTION THAT THE ROLLING ROLL (31), WHEN THE ROLLING ROLL (31) IS REVOLVED, IMPARTS TO THE METAL PIPE (10) A THRUST FORCE TENDING TO MOVE THE METAL PIPE (10) FORWARDLY.
