Abstract: A method for production of a horology assembly of two components, comprising (i) supplying a first component (2) being a spring, and comprising at least one element made of elastic material provided with a tongue (20); supplying a second component (3) provided with at least one cut-out or opening (31, 32); permanently assembling the two components. The two components cooperate by means of an obstacle such as to create the assembly, and in particular the tongue is accommodated in the at least one cut-out or opening (31, 32).

Abstract: The invention relates to a method for shaping a barrel spring made of a unitary ribbon of metallic glass that comprises calculating the theoretical shape to be given to said unitary ribbon of metallic glass so that each segment, once the spring is fitted in the barrel, is subjected to the maximum bending momentum, shaping said ribbon by imparting bends thereto characteristic of said free theoretical shape in order to take into account a potential reduction of the bends once the ribbon is released, relaxing the ribbon in order to set the shape thereof by heating the same, and cooling down said ribbon.

Abstract: Mainspring for a mechanism driven by a motor spring, especially for a timepiece, formed from a ribbon of metallic glass material. This ribbon is monolithic and has a thickness of greater than 50 ?m.

Abstract: In a method of making an axle element for a motor vehicle, a rod-shaped semi-finished product of aluminum is use used as starting material and heated to a desired shaping temperature. A first end of the semi-finished product is upset in a cavity of a shaping die by means of a first punch. Subsequently, the other end of the semi-finished product is compressed in the cavity by a second punch, whereby compressed material is forced into a branch of the cavity to form a pre-forge part with a leg portion. The pre-forge part is then forged into a finished axle element, e.g. a swivel bearing.
