One feature of the invention is a yarn spinning and/or twisting process, in which a yarn runs between a yarn feeding means (1) towards a yarn picking means, said yarn picking means being connected to driving means for rotating the yarn picking means at a predetermined speed, in which a balloon region is generated at a point located between the feeding means (1) and the picking means by the presence of twisting means. The fact that the value of the rotation speed of the yarn twisting means is such that it generates a helical path with oscillating spiral diameters along the distance between the yarn feeding means (1) and the yarn picking means, so that the path of the yarn, by the operation of the twisting means, creates a body of revolution from a diameter generating a balloon that has at least a hyperboloid structure (E) forming at least two balloon regions (B) consecutive to each other. A second feature of the invention is the yarn spinning and/or twisting machine comprising: a yarn feeding means (1) for supplying at least one yarn (3); a yarn picking means for the yarn handled (3); twisting means arranged between the yarn feeding means and the yarn picking means, which generate a diameter generating (DB) a balloon region of the yarn (3) in an area generating a balloon region (B) with a generating diameter (DB); and driving means (4) connected to the yarn feeding and/or picking means. The machine does not include elements limiting the balloon and said machine is characterized in that the distance (LB) between the guiding means and the area generating a balloon region is at least twice the diameter generating the balloon (DB), so that at least two balloon regions (B) are generated between the guiding means (8) and the area generating a balloon region. Last, another feature of the invention is a method for transforming a yarn spinning and/or twisting machine, including a step in which the height of the balloon region (LB) is increased so that, by operating the twisting means, a body of revolution is created from a diameter generating a balloon that has at least a hyperboloid structure (E) that forms at least two balloon regions (B) consecutive to each other.
