An apparatus is provided for continuously shaping a metal tube by means of shaping rollers, which are arranged around the tube and consist of pairs of rollers disposed on opposite sides of the axis of the tube. It is desired to permit an adaptation of the apparatus to tubes which differ in size and in final shape. This is accomplished in that each shaping roller is radially adjustable relative to the tube and is mounted to be pivotally movable about a pivotal axis which is parallel to the axis of the tube. Said pivotal axis extends through the center of curvature of an arc of 2 circle which is at least approximated by that portion of the rolling contour which is defined by said shaping roller or said pivotal axis is spaced from said center of curvature in a direction which is parallel to the axis of said shaping roller.
