Definitions

  • the invention as set out in the title of this specification, relates to a method for transforming a thread twisting and/or spinning machine and a thread twisting and/or spinning machine modified according to said method which provides, to the use it relates to, advantages and novel features, described in detail below and which entails an improved alternative for the current state of the art.
  • the object of this invention is a thread twisting and/or spinning machine modified to carry out said thread twisting and/or spinning by carrying out the threads rotate with numerous balloon regions, which comprises an attachment that increases the height of the area of the balloon region, that is, the separation distance between the guiding means in the feeding area of the thread and the twisting means of said thread for its winding to the pickup spool, thus the essential aspect of the present invention is a method for transforming the thread twisting and/or spinning machine which carries out the spinning and/or twisting process with only one balloon region into a machine which carries it out with numerous balloon regions by means of the addition of an attachment to said machine which, without modifying other elements thereof, increases the height of the balloon region, that is, the separation distance between the guiding means in the feeding area of the thread and the twisting means of said thread in order to wind it to the pickup spool.
  • the field of application of the present invention falls within the industry sector involved in the manufacturing of thread twisting and/or spinning machines.
  • WO2018122625A1 discloses a thread twisting and/or spinning method to avoid said problem with numerous balloon regions instead of a single region; namely a method wherein a thread passing between a thread feeding means (such as at least one spool for example) towards a thread pickup means, said thread pickup and/or winding means being connected to motor-driven means to rotate the thread winding means at a default speed, where a balloon region is produced at a point located between the feeding means and the winding means due to the presence of twisting means, specifically being differentiated in that the rotation speed value of the thread twisting means is such that the track followed by the thread between the feeding means and the pickup (or winding) means, due to the activation of the twisting means, produces a helical track with oscillating spiral diameters throughout the existing distance between the feeding means and the thread pickup and/or winding means, in such a way that a revolution body is created which has at least one hyperboloid structure creating at least two balloon regions that are consecutive to each
  • twisting by means of numerous balloon regions offsets the work tension, in such a way that the tension produced by the twisting means is lower than the tension produced in the traditional spinning and/or twisting processes, which, in turn, provides remarkable advantages.
  • the method of the cited document envisages the increase of the height of the area occupied by the balloon region, preferably, so that said height is at least twice the diameter generating the balloon region.
  • the machine is usually modified to increase the separation distance between the guiding means, which are located in the top part of the balloon region, under the thread feeding area, and the twisting means of said thread to be winded to the pickup spool, in the lower part of the such balloon region.
  • the object of the present invention is the development of an improved modified machine in order to increase said height of the area occupied by the balloon region by applying a method to carry out such modification, which is much simpler, easy to perform and, consequently, more practical and economic than through the currently used system.
  • the machine proposed by the invention is a thread twisting and/or spinning machine which is modified to carry out said thread twisting and/or spinning process by making said threads rotate with multiple balloon regions and for this purpose, unlike the system used so far consisting in the elevation of the set of elements of the machine which feed the thread and determine the guiding means thereof to increase the height of the area occupied by the balloon region, that is, the separation distance between the guiding means in the thread feeding area and the twisting means of said thread to be winded to the pickup spool, it simply has an additional guiding accessory which obtains the same effect, that is, to increase the height of the area occupied by the balloon region by increasing the separation distance between the guiding means in the feeding area of the thread and the twisting means of said thread to be wound to the pickup spool.
  • Said additional guiding accessory replaces the conventional guiding means of the thread and increases said height of the area of the balloon region to allow the thread twisting through the formation of two or more balloon regions located in a point just downstream such thread feeding rollers to increase the aforementioned separation distance between the guiding means in the thread feeding area and the twisting means of said thread to be wound to the pickup spool by lifting the position of the means.
  • the said additional guiding accessory consists of a clip that is installed in the machine just at the outlet of the thread from the rollers constituting the feeding means thereof, said clips being provided with one or more thread-guide hooks that guide the thread at the top end of the area of the balloon region, thus increasing the height of said area so that there can be two or more balloon regions when the thread is twisted.
  • the aforementioned additional guiding accessory consists of a thread lifting mechanism before the twist of the thread, for example a set of rollers linked, optionally to a conveyor belt (strips), along which the thread runs forming a loop at the outlet of the feeding rollers, this set of rollers being placed in such a way that said loop raises the thread before twisting the thread above the point where it emerges from the feeding means, thus increasing the height of the area of the balloon region so that there may be two or more balloon regions when the thread is twisted.
  • a thread lifting mechanism before twisting the thread is by means of rollers.
  • the invention relates to the transformation method of a thread twisting and/or spinning machine into the modified machine described above to carry out said thread twisting and/or spinning process by making them rotate with numerous balloon regions through the increase of the height in the area covered by the balloon region, that is, by increasing the separation distance between the guiding means of the thread and the twisting means of said thread, which comprises at least the following stages:
  • the thread twisting and/or spinning machine is modified by increasing the height of the area covered by the balloon region so that it has two or more balloon regions where the thread is twisted, increasing the separation distance between the guiding means in the thread feeding area and the twisting means of such thread to be wound to the pickup spool, without the need to lift the whole set of elements consisting of the guiding means of the thread and the feeding means, which entails a much simpler and cheaper modification that can also be made much more quickly and, thus, not affect the production.
  • the additional guiding accessory is a thread lifting mechanism before twisting the thread comprising a set of connected rollers along which the thread runs forming a loop at the outlet of the feeding rollers, lifting the thread above the point where it emerges from said feeding means.
  • the set of rollers (32) comprises a conveyor belt (33).
  • the thread as it moves together with the conveyor belt, does not suffer any friction and, therefore, it does not deteriorate, and at the same time, it is a negative feature for a good quality of the fabric to be produced with the thread and it is produced as a result of the thread friction with guiding elements such as hoops or similar ones.
  • the additional guiding accessory (3') comprises compaction means of the thread during the lifting thereof.
  • the compaction means serve to reduce the hairiness of the final thread.
  • the compaction means of the thread are already well-known in traditional technologies and are incorporated during the transport of the thread in the final stage thereof just before being spun and turned into a thread. They can mainly be of the mechanical type or by means of air. We do not go into detail regarding the compaction systems or means, but we do focus on where it is located during the new lifting course of the thread resulting from the present invention.
  • figure 1 shows, very schematically, the essential elements of a conventional ring thread twisting and/or spinning machine that is not modified, that is, it only has a single balloon region (a) and, basically, they consist of the thread (2) feeding means (1), preferably a set of standard rollers, conventional guiding means (3) which are located at a distance under the feeding means (1), and demarcate the top end of said balloon region (a) at the top, and twisting (4) and winding (5) means of said thread (2) perpendicular to a pickup spool (6), which preferably consist of a tensor rotating around a ring, determining the lower end of the balloon region (a) and which have been located above the spindle which shall form the cited spool (6) instead of surrounding it, in order to ensure a better incorporation of such elements.
  • the thread (2) feeding means (1) preferably a set of standard rollers
  • conventional guiding means (3) which are located at a distance under the feeding means (1), and demarcate the top end of said balloon region (a) at
  • Figure 2 shows how, according to the prior art, the modification method of said machine to increase the height (h) of the balloon region area (a), between the guiding means (3) and the twisting (4) and winding (5) means in order to obtain two or more balloon regions (a), consists of lifting, as it is, all the elements located in the top part of said balloon region (a), that is, the guiding means (3) and the feeding means (1) of the thread (2), by moving them, without modifying its number or structure or configuration, to a higher position that coincides with the suitable position to obtain the necessary separation height (h) between said guiding means (3) and the twisting (4) and winding (5) means to have the desired two or more balloon regions (a).
  • figures 4-A, 4-B show, in order to carry out the modification to increase the height (h) of the area of balloon regions (a) in order to obtain two or more balloon regions (a) in the machine of the invention, and according to the proposed method herein, the replacement of the conventional guiding means (3) by an additional guiding accessory (3') located in a point just downstream the feeding means (1) of the thread (2) is envisaged.
  • Figure 3 refers to a variant which does not fall under the scope of the claims and shows how said additional guiding accessory (3') comprises a clip (30) installed in the machine just at the outlet of the thread (2) from the rollers constituting the feeding means (1) of the machine, and said clip (30) may be equipped with one or more thread-guide hooks (31) guiding the thread (2) in the top end of the balloon region area, increasing this way the height (h) of such area so that there can be two or more balloon regions (a) when the thread is twisted.
  • said additional guiding accessory (3') comprises a clip (30) installed in the machine just at the outlet of the thread (2) from the rollers constituting the feeding means (1) of the machine, and said clip (30) may be equipped with one or more thread-guide hooks (31) guiding the thread (2) in the top end of the balloon region area, increasing this way the height (h) of such area so that there can be two or more balloon regions (a) when the thread is twisted.
  • Figures 4-A and 4-B show how in a second variant of the embodiment, in fact it is a preferred variant, the additional guiding accessory (3') is made up of a thread lifting mechanism before twisting the thread, preferably comprising a set of rollers (32) connected with each other on which the thread (2) runs in such a way that said thread (2) forms a loop just at the outlet of the rollers representing the feeding means (1) of the thread where said set of rollers (32) are incorporated, in such a way that said loop lifts the thread (2) above the point where it emerges from said feeding means (1), increasing this way the height (h) of the area of the balloon region so that there can be two or more balloon regions (a) when the thread is twisted.
  • a thread lifting mechanism before twisting the thread
  • the aforementioned set of rollers (32) which are the preferred variant of the additional guiding accessory (3') envisages the possibility of moving the relative position thereof to hold the thread (2) between them at one point or another, where appropriate, as shown in figures 4-A and 4-B .
  • the set of rollers (32) comprises a conveyor belt (33) that maintains the integrity and the guiding of the thread during the lifting thereof.
  • the additional guiding accessory (3') comprises compaction means of the thread during the lifting thereof.
  • the compaction means serve to reduce the hairiness of the thread with the consequent reduction of the hairiness of the final thread.
  • the compaction means can be mechanical or by means of air.
