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.
