    Spinning and / or twisting process of yarns and spinning and / or twisting machine
    DESCRIPTIVE MEMORY
    OBJECT OF THE INVENTION
    The purpose of the present application is to register a spinning and / or twisting process of threads with multiple balloon regions, the procedure of which is intended to be carried out by means of a wire twisting machine or spinning machine.
    More specifically, the invention proposes the development of a method of spinning and / or twisting of threads that allows to work with a higher speed without thereby increasing the tensions of the yarn that occur in the spinning and / or twisting process as well as a spinning and / or twisting machine using such a method.
    BACKGROUND OF THE INVENTION
    In the textile sector, and in particular in the spinning and twisting sector, the use of continuous ring spinning machines, ring twisting, multi twisting twisting, double twisting, vertical wiring, cabling twisting, etc. is well known.
    All these machines to provide twist to the thread are forced to spin the thread at a distance from the center of rotation in order to save a space occupied by a part of the machine and it generates a figure of revolution called quot ; football; This balloon is defined by a zone or volume of revolution with a central axis of rotation, for example, with a conical volume.
    The tendency of spinning and twisting machine manufacturers is to suppress or reduce the ball by physically limiting it in order to avoid an increase in 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 reduced, or in other words, it cannot be increased so it negatively affects productivity.
    DESCRIPTION OF THE INVENTION
    The present invention has been developed in order to provide a method that 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 the accompanying description. continuation .
    It is therefore an object of the present invention to provide a method of spinning and / or twisting yarns with multiple balloon regions, in which a thread passes between a thread feeding means (such as at least one coil) towards a thread collection means, said means for collecting and / or winding yarn linked to motor means for rotating the thread collection means at a predetermined speed, in which a balloon region is generated at a point located between the feeding means and the collection means by the presence of twisting means. In particular, the invention is characterized by the fact that the rotation speed value of the thread twisting means is such that the path followed by the thread between the feeding means and the collection (or winding) means, by the actuation of the twisting means, generates a helical path of the wire to be manipulated with oscillating spiral diameters along the distance between the feeding means and the means for collecting and / or winding the thread, such that a body is created of revolution that has at least one hyperboloid structure that forms at least two consecutive balloon regions.
    Therefore, torsion is produced by multiple balloon regions that compensate for the working tension in such a way that the tension produced by tension means is lower than in traditional spinning and / or twisting processes.
    Thanks to these characteristics, it is possible to produce yarns and / or twists of yarn at a higher speed and therefore, with a higher productivity index, with a low thread tension, and a lower energy consumption that allows to reduce production costs and increase thread quality
    The tensions that can be generated in the thread due to the speed of rotation, centrifugal forces, are counteracted at the inflection points between the balloon regions.
    Another advantage of this method is the fact that it allows the twisting of very fine threads with a low degree of tension, which broadens the manipulation of new very delicate threads that are broken at present when working with tensions that cannot be absorbed.
    5 This method is suitable for all threads, fibers, filaments, ropes, tapes, etc., as wellas natural, synthetic and artificial materials. It may be especially suitablefor handling fiberglass, carbon, aramid fibers, etc., since it allowswork at a higher speed and with a lower degree of tension.
    10 Preferably, the height of the balloon regions is at least twice the revolution diameter of the balloon region.
    Also preferably, the height of the balloon regions is at least twice the height of the collection means.
    15 Similarly, it may also be preferable that the height of the balloon regions is at least twice the height of the feeding means.
    According to another aspect of the invention, the thread passes through a tensioning means
    20 located at a point prior to the means for collecting and / or feeding the wire, in particular, in the spinning of threads per ring and the twisting of rings. In the case of double torsion machines, direct wiring machines and vertical machines, the tension is also regulated by other external means.
    Preferably, the tensioning means in the ring spinning and ring twisting comprises a cursor that is coupled to a rocker linked to the winding coil.
    It is another object of the invention to provide a spinning and / or twisting machine, comprising:
    30 -a yarn feeding means, -a yarn collecting means, -torsion means arranged between the yarn feeding means and the collecting means that generate a diameter region of yarn balloon region in a generating zone of balloon region, -a motor means linked to the feeding medium and / or thread collection means. and -a guide means for guiding the thread located at a point close to the collection means and / or feeding medium.
    Said machine is characterized by the fact that the distance between the guiding means and the balloon region generating area is at least twice the balloon generating diameter, such that at least two balloon regions are generated between the means of guided and the region generating the ball region.
    10 Mention that in the case of spinning and twisting machines for rings, an increase in the number of balloon regions is associated with a reduction in the dimensions of the cursor and consequently, the weight of the cursor itself with the consequent advantages that it entails.
    Other features and advantages of the method 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:

    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.
    In all preferred embodiments of the spinning and twisting machines described below, the speed of rotation of the winding coil is such that a helical path is generated, with an oscillating spiral diameter (S), ( see figure 7) along the distance (LB) between the feeding means and the winding coil, such that a body of revolution is created having two hyperboloid structures
    20 (E) consecutive forming a plurality of consecutive balloon regions (B) with each other.
    Figure 1 shows a ring spinning machine that has a wire feed system at the top, indicated in general with reference (1) which is of the conventional type, so it is not going to enter greater detail in its description, while in the lower part there is provided a bobbin (2) for collecting thread (3) that 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 called cursor (5) placed on a rocker (6) that collects the thread
    30 which has been twisted and stores it in the coil (2). Said cursor (5) can be seen more clearly in the enlarged detail included in Figure 1.
    During the process of winding the thread (3), in the embodiments shown here, three balloon regions (8) (without being the number of limiting balloon regions) are formed between a thread guiding means (8) (indicated schematically), such as a
    small diameter ring and a balloon region generating region caused by twisting means so that a region generating diameter (08) of the structure region with multiple yarn balloon regions is generated, in which two throttling regions are defined or hyperboloids (E) that allow reducing the degree of thread tension.
    Mention that the distance (LB) between the guiding means and the balloon region generating area is at least twice the balloon generating diameter (OB), such that at least two balloon regions are generated between the guiding means and the region generating the balloon region.
    It should be mentioned that the number of balloon regions (B) can be increased in number
    or be reduced (the minimum being two balloon regions) by increasing or reducing the distance (LB) between the wire guiding element and the element responsible for causing the twist, in this case represented, the cursor (5).
    15 Figure 2 shows a twisted ring machine with a wire feed roller from a static fillet in which the same common elements have the same numerical references, the feeding means being indicated generally with the reference (1), arranged at the top and the coil (2) of
    20 thread collection (3) at the bottom of the machine.
    In figure 3 a ring twisting machine is shown, which is especially suitable for the processing of fiberglass, in which the same common elements have the same numerical references being the feeding means (1) arranged in
    25 the upper part and the thread collection bobbin (2) (3) in the lower part of the machine, whereby the thread direction is in the downward direction, as in the embodiments of machines shown in figures 1 and 2.
    Figure 4 shows a twisting twisting machine in which the same common elements have the same numerical references.
    Figure 5 shows a vertical wiring machine with two wires in which the same common elements have the same numerical references, where the direction of operation is ascending as is the machine shown in Figure 35 4 and indicated by the arrow (f), that is, the pickup coil is arranged in the part
    upper while in the lower part are located the feeding means of a first and second wires that are interwoven with each other. In this machine, the thread (3) and the additional thread (H2) are joined, in which the additional thread (H2) is supplied by a feeder (7).
    5 In Figures 6 to 8, a geometric contour is shown that adopts the thread during thetwisting process, in which three balloon regions are formed (figure 6) as well asalso the real path that a thread can make during the process of handlinga thread.
    The details, shapes, dimensions and other accessory elements used in the manufacture of the method of the invention may be conveniently substituted by others that do not depart from the scope defined by the claims included below.
