PROCESS FOR SPINNING OR TWISTING YARNS, MACHINE FOR SPINNING OR TWISTING YARNS AND METHOD TO TRANSFORM A MACHINE FOR SPINNING OR TWISTING YARNS. A feature of the invention should be a process of yarn spinning or twisting, in which a yarn runs between a yarn feeding means (1) towards a yarn picking means, the said yarn picking means being connected to driving means to rotate the yarn picking means at a predetermined speed, in which a stretch of balloon is generated in 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 existing 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 stretches of balloons (B) consecutive to each other. A second feature of the invention should be the yarn spinning or twisting machine that includes a yarn feeding means (1) to supply at least a yarn (3), a yarn picking means for the yarn handled (3), twisting means arranged between the yarn feeding means and the yarn picking means that generate diameter generating (DB) a stretch of balloon of the yarn (3) in an area generating a stretch of balloon (B) with a generating diameter (DB), driving means (4) connected to yarn feeding or picking, and does not include elements limiting the balloon and is characterized in that the distance (LB) existing between the guiding means and the area generating a stretch of balloon is at least two times the diameter generating the balloon (DB), so that at least two stretches of balloon (B) are generated between the guiding means (8) and the area generating a stretch of balloon. Last, another feature of the invention should be the method to transform a yarn spinning or twisting machine including a set in which the height of the stretch of balloon (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 stretches of balloons (B) consecutive to each other.
