    Improvements introduced in the main patent nº 201631732 entitled "spinning and / or twisting process and spinning and / or twisting machine"
    DESCRIPTIVE MEMORY OBJECT OF THE INVENTION
    The purpose of the present application is the registration of Improvements introduced in the main patent nº 201631732 which is entitled "spinning and / or twisting process and spinning and / or twisting machine", the object of which is described in the main claim
    one.
    The field of application of the invention is obviously included within the industrial sector dedicated to the handling of threads of any type, whether they are fibers of natural, artificial and synthetic origin, as well as technical threads such as fiberglass, fiber carbon, aramid and hybrid threads or mixtures thereof. BACKGROUND OF THE INVENTION
    It is well known in the spinning and twisting sector, the use of spinning machines of the continuous ring type, ring twister, multiple twist twister, double twist, vertical wiring, cabling twister, etc.
    All these machines that apply a degree of twist to the thread that has to be manipulated, must spin the thread at a distance from the center of rotation in order to save a space (or volume) occupied by components of the machine itself, generating therefore a figure of revolution that is called in the textile sector "ball." This balloon is defined by a zone or volume of revolution defined by a central axis of rotation, which can adopt a conical geometry.
    Until now, it has been observed that a tendency of spinning and twisting machine manufacturers is to suppress or reduce the size of the ball in order to avoid an increase


    of the diameter of the ball and reduce the height of the ball as much as possible. In this way, the tensions generated in the thread for the twisting and / or spinning process are lower to avoid possible damages to the thread, which affect the quality of the thread, breakages during the productive process, so that the speed of rotation or angular is limited and has to be lower, thereby negatively affecting the productivity ratio.
    To solve the problem described above, it is known a procedure described in Spanish patent application No. 201631732 of the same applicant that allows to increase the productivity ratio, allowing higher working speeds. DESCRIPTION OF THE INVENTION
    The present invention has been developed in order to provide improvements introduced in the main patent No. 201631732 which is configured as a novelty within the field of application and resolves the aforementioned drawbacks, also providing other additional advantages that will be apparent from of the description that follows.
    It is therefore an object of the present invention to provide improvements introduced in the main patent No. 201631732 which is entitled "spinning and / or twisting process and spinning and / or twisting machine", in which a thread passes between a thread feeding means and a thread collecting means, said thread collecting means being linked to motor means for rotating the thread collecting means at a predetermined speed, in which a region is generated of ball at a point located between the feeding means and the collection means by the presence of twisting means, the speed of rotation of the thread twisting means being such that a helical path of the thread is generated with diameters of oscillating spirals along the distance between the feeding means and the thread collecting means, such that the thread path, by the actuation of the twisting means, creates a body of revolution from a balloon generating diameter having at least one hyperboloid structure that forms at least two consecutive balloon regions with each other, which are characterized by the fact that the total height defined by at least two balloon regions


    it is in a range of 5 to 50 times the generating diameter of the balloon region, and more preferably, 5 to 25 times the generating diameter of the balloon region.
    This height range is preferably distributed so that for generating diameters, such as 200mm or 216mm or 250mm or 300mm or 330mm or 400mm or 500mm, and depending on the thickness of the thread to be processed, 2 balloon regions can be obtained (it is that is, a hyperboloid structure) with heights of 5 times the generating diameter of the balloon region, or as the thickness of the wire increases, this height needs to be increased to 6 times the generating diameter of the balloon region, or 7 times the generator diameter of the balloon region, even 8 times the generator diameter of the balloon region.
    On the other hand, if the generating diameter is reduced to values, such as 165mm, or 140mm or 120mm or 100mm until it reaches 30mm, so that two balloon regions are obtained, the height is determined with a ratio of 5 times the generating diameter of the balloon region, or six times the generating diameter of the balloon region,
    or even seven times the generating diameter of the balloon region evolving said value differently than with large generating diameters.
    According to another aspect of the invention, the process can be carried out by multiple hyperboloid structures that define a number of hyperboloids between 2 and 20.
    In working conditions with certain parameters, to increase the balloon regions, which in turn implies an increase in hyperboloid structures, it is achieved by increasing the height of the balloon region and, consequently, increasing the value of times the generating diameter of the already established balloon region, such that height values of the balloon region are increased from 5 to 50 times the generating diameter of the balloon region as it is desired to increase the balloon regions, and by consequently, increasing the hyperboloid structures that would pass from 2 to 20 as this height is increased.


    Thanks to these characteristics, a stable configuration of yarn with multiple balls is obtained during the manipulation thereof in a spinning machine or the like so that a balance between strains of the yarn to be handled and working speed is achieved, and consequently it is obtained Optimum process efficiency.
    According to another aspect of the invention, the process is carried out by means of multiple hyperboloid structures that define a number of hyperboloids between 2 to
    twenty.
    Other features and advantages of the process object of the present invention will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which: BRIEF DESCRIPTION OF THE DRAWINGS
    Figure 1.- It is a schematic view of an embodiment of a continuous ring spinning machine employing the method according to the invention, including a detail view of the cursor; Figure 2.- It is a schematic view of a path that a thread can make in a process according to the present invention; and Figure 3.- It is a schematic view showing the superposition of the geometric shape obtained with the process of the invention on the thread path represented in Figure 2. DESCRIPTION OF A PREFERRED EMBODIMENT
    In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
    Figure 1 shows a ring spinning machine that has a wire feeding system at the top, shown schematically and indicated


    in general with reference (1), being of any type currently available in spinning machines, so it is not going to go into greater detail in its description. In the lower part there is provided a bobbin (2) for collecting the wire (3) which rotates in a motorized manner by conventional motor means (4) schematically represented. The thread (3) that is wound in the bobbin enters perpendicularly with respect to the side wall of the bobbin when the thread is passed through a tensioning element substantially annular with an open section, called cursor (5), which is placed in a rocker (6) that picks up the thread that has been twisted and stores it in the bobbin (2). Said cursor (5) can be seen more clearly in the detail on a larger scale present in Figure 1.
    It should be mentioned that the speed of rotation of the winding coil and the value of tension generated by tension means is such that a helical path is generated, with an oscillating spiral diameter (S), along the distance ( LB) existing between the feeding means and the winding coil, thus creating a body of revolution that has three consecutive hyperboloid structures (E) that form a plurality of consecutive balloon regions (B) with each other, as can be seen in figures 2 and 3 more clearly.
    During the process of winding the thread (3), in the embodiments shown here, four balloon regions (B) (without being the number of limiting balloon regions) are formed between a thread guiding means (8) (indicated by schematic form), for example, a small diameter ring and a balloon region generating region caused by torsion means as well as tension means so that a region generating diameter (DB) of the structure region with multiple regions is generated of ball of yarn, more specifically three regions of throttling or hyperboloids (E) have been defined that allow to reduce the degree of tension of the thread and work with an optimum speed of rotation, providing a higher productivity ratio compared to prior art machines .
    In a non-limiting embodiment, with a generating diameter (DB) of 36mm, eight hyperboloid structures (i.e. nine balloon regions) with a balloon region height equivalent to 50 times the generating diameter of 36mm can be obtained for


    a thread with a title of 30Nm.
    "Title" is understood as the relationship between the weight and length of a thread, the first being a fixed value and the second variable value.
    The details, shapes, dimensions and other accessory elements of the invention may conveniently be replaced by others that do not depart from the scope defined by the claims included below.
