ABSTRACT OF THE DISCLOSURE This invention provides a method for rolling a tube from a larger diameter into a smaller diameter. The method comprises the steps of contacting at least one area of the outside surface of the tube with the surface of at least one roll rotatable about its axes, during which the roll and tube are brought into a relative contact movement with respect to each other. The step of contacting is carried out relative to the contact surface of the roll and tube, as defined between two planes spaced in a longidutional direction of the tube, so that the contact is displaced relative to the longitudinal axis of the tube, whereby the contact surface of the rotatable roll with the deformed tube follows one or more spaced spirals of the conically rolled tube or one or more helical lines of the cylindrical rolled tube. An apparatus for carrying out the method is also provided. The method and apparatus of this invention overcome such disadvantages as interchanging rolls and using internal mandrels for rolling tube of different size and diameter.
