Method for producing a connecting element, connecting element, and rolling tool

A method for producing a connecting element comprising at least two spherical sections, wherein two spherical sections are directly adjacent to each other, or wherein two spherical sections are connected to each other by means of a connecting section, the method comprising

• rolling a single-piece blank, which is cylindrical at least in sections, between at least two rolling tools and shaping portions of the single-piece blank into the at least two spherical sections and optionally the connecting section during the rolling,
• further including holding the blank at least before the beginning of the rolling at a supply head of the blank and prior to the insertion of the blank between the at least two rolling tools, wherein the supply head consists of a disk at a first terminal end of the blank that it is wider than it is tall and projects in the radial direction to a supply head radius that is greater than a body radius for the body section of the blank which is cylindrical and extends from the supply head to a second terminal end of the blank.
