Definitions

  • the present invention relates to a method of manufacturing a wire having flames and which is composed of at least one core wire, fed continuously at a substantially constant speed v, and at least one wire effect, fed continuously at a speed v ′ substantially constant and greater than v in order to obtain an overfeeding of the effect yarn relative to the core yarn, these yarns being brought together in one place to assemble them, by integration by simultaneously texturing .
  • the object of the invention is to provide a method targeting in particular the son of the aforementioned type, composed of a wire or a group of core wires and at least one wire or group of effect wires, the texturing takes place in a nozzle in which compressed air circulates and more particularly threads, known under the name "TASLAN", composed of core and effect threads of the POY type (Pre oriented yarn) which undergo before their passage through the nozzle, where the texturing takes place, a stretching combined with a rise in temperature.
  • TASLAN a nozzle in which compressed air circulates and more particularly threads, known under the name "TASLAN”, composed of core and effect threads of the POY type (Pre oriented yarn) which undergo before their passage through the nozzle, where the texturing takes place, a stretching combined with a rise in temperature.
  • the method according to the invention offers the following advantages: it allows, for the production of flame wires, a wire feeding speed which is as high as the feeding speed for obtaining a wire, flameless, with simple overfeeding of the effect wire with respect to the core wire; it allows a flame generation frequency which can reach 150 flames per second, given that this frequency is limited to this value by the performance of the equipment existing to date and in particular the perfor texturing nozzle mances; it makes it possible to obtain an almost constant titration wire over a determined length of wire; it allows the reproducibility of the same titration from one spindle to another, and it offers the possibility of reproducing the same wire at different times on the same machine or another machine of the same type.
  • said method consists in alternately temporarily accumulating, upstream of the aforementioned place of meeting of the wires, considering the direction of feeding of the latter and preferably near this place, an amount of effect wire, while feeding the latter continuously to said place and at a speed at least equal to the speed v of the core wire, and to release the quantity of wire accumulated in order to increase, during these periods of release of the quantities of threads accumulated, overfeeding the effect thread with respect to the core thread and thus creating the flames of the thread.
  • the amount of accumulated wire is released in a shorter time than the accumulation time.
  • the amounts of accumulated effect yarn are substantially equal.
  • the accumulation time of the quantity of above-mentioned effect yarn is constantly varied so that the distance between two immediately adjacent flames is not constant.
  • the above-mentioned accumulation time is varied randomly.
  • the invention also relates to a device, for the implementation of the aforesaid method, which is particularly simple and which can easily, on the one hand, be integrated into existing equipment for the manufacture of wires with simple supercharging of the wire or wires effect and, on the other hand, be adapted to the various shapes and dimensions of flame desired.
  • this device comprises, upstream of the above-mentioned location, fixed means for guiding the effect son or wires arranged to guide this wire or each of these effect son at two separate points while ensuring a cross section tension between these two points as well as mobile means arranged therebetween, to act periodically on the section of wire included between these two points and in a direction transverse to the direction of travel of this section of wire, in order to accumulate the quantity of aforementioned effect yarn, the latter means being further arranged to release, after each accumulation of yarn, the quantity of yarn accumulated.
  • the method according to the invention and illustrated in the drawings is intended for the manufacture of a wire 1 having flames 2 and which is composed of at least one wire or group of core wires 3, fed continuously at a speed v substantially constant, and at least one wire or group of wires of effect 4, supplied continuously at a speed v ′ substantially constant and greater than v, in order to obtain an overfeeding of the wire or group of wires of effect 4 relative to the core wire or group of wires 3.
  • These wires or groups of wires 3 and 4 are brought together in a place 5 to assemble them, at 6, by integration, by texturing them simultaneously.
  • this method consists in alternately temporarily accumulating, upstream of the meeting place 5 of the wires or groups of wires 3 and 4, considering the direction of supply of these, shown schematically by the arrows 7, and preferably near this location 5, a quantity of wire or group of effect son, while feeding the latter to said location 5 continuously and at a speed at least equal to the speed v of the wire or group of core wires 3 and to release the quantity of wire accumulated, in a time equal to or shorter than the time of accumulation, according to the desired flames, in order to increase, during these periods of release of the quantities of son accumulated, overfeeding the wire or group of effect wires 4 with respect to the wire or group of core wires 3 and thus creating the flames 2 of the wire 1.
  • the wire 1 according to the above process has an almost constant titration over a determined length of wire and can be reproduced at different times on the same machine as well as from one spindle to another, given that the wire 1 is produced continuously using continuously fed core and effect wires.
  • the method provides for scrambling of the flames, that is to say an irregular distribution of the flames 2 on the wire, which is obtained by constantly varying the accumulation time of the aforementioned quantity of effect yarn 4 and preferably this variation in accumulation time takes place in a random manner.
  • the method according to the invention is advantageously, as illustrated in FIG. 5, associated with the method of manufacturing a "TASLAN" wire according to which core 3 and effect 4 son, of POY type, are used, to which it is subjected, upstream of the place 5 where they are joined together to texture them, at 6, in a nozzle 7 through which compressed air circulates and upstream of the place 8 where one temporarily accumulates the aforementioned quantity of effect yarn 4, drawing on cylinders 9 driven in rotation about their axis, according to arrows 10 and, in the same direction as the direction of supply of the core 3 and effect 4 yarns , this stretching being combined with a rise in temperature by passing the wires 3 and 4 over heating fingers 11 brought to a temperature of at least 50 ° C.
  • the wire 1 comprises several effect wires 4
  • one acts on several or on all of the effect wires 4 one can, depending on the desired flame effects, ensure that the accumulation of a quantity of one of the effect wires as well as the release of this accumulated amount is offset from the accumulation and release of other effect threads.
  • effect yarns 4 of different colors By using the abovementioned accumulation technique, yarns 1 whose flames 2 have a great diversity of colors.
  • the core and effect wires can be fed at a speed between 360 and 480 m / minute.
  • the device for implementing the above-mentioned method which is to be associated with a machine for the production of wire composed of core threads and threads with a supercharged effect compared to the threads core and in particular to a machine for manufacturing "TASLAN" yarns, comprises, upstream of location 5, fixed guide means 12 for the effect yarn (s) 4 which are arranged to guide this yarn or each of these effect wires at two separate points 13 and 14 between which the section 15 of effect wire lying between these two points is under tension, as well as mobile means 16 which are between these points 13 and 14, for acting periodically on the section 15 of effect yarn 4 lying between these two points and in a direction transverse to the direction of travel of this section of yarn, in order to accumulate the quantity of aforementioned effect yarn, the latter means 16 being further arranged to release suddenly, after each accumulation wire ion, the amount of wire accumulated.
  • the fixed means 12 are constituted, as shown in most of the figures, by two guide eyelets 17 through which the effect wire 4 passes.
  • These eyelets 17 are advantageously of adjustable position in order to be able to adapt them to the section length 15 of desired wire and adjust their position relative to the movable means 16.
  • One of these eyelets 17 can be replaced, as shown in FIG. 18, by a guide tube 21 ′.
  • the mobile means 16 are arranged to act on the section 15 of effect wire situated between the guide means 12 and comprise a surface of revolution 18 on which a zone 19 of this section of wire is permanently supported and which is driven, continuously and in the same direction, in rotation about an axis 20.
  • the profile of this surface of revolution 18 and its position relative to the guide means 12 are such that, either during a rotation of 360 ° ( see for example Figures 19 to 22), either during a rotation of a fraction of 360 ° (see Figure 16) or during a rotation of a multiple of 360 ° (see Figure 17), around from the axis 20, the length of the section 15 of effect yarn comprised between the said guide means 12 increases progressively to reach a maximum, with a view to the abovementioned accumulation, and when this maximum is reached, the said length passes, for example abruptly when using a cam 24 of the type illustrated in particular in FIGS. 7 to 12, to a minimum to release the quantity of wire accumulated in order to accelerate the overfeeding of the effect wire 4 relative to the wire core 3 and thus allow the formation of a flame 2.
  • the surface of revolution 18 may belong to a cam 24. If one follows the phases illustrated in FIGS. 7 to 12, it can be seen that the length of the section 15 of accumulated wire ⁇ l between the guide eyelets 17, which corresponds to the total length of the section L + ⁇ l from which the distance L separating the eyelets 17 is subtracted, increases progressively, as shown in the graph in FIG. 6 , to reach a maximum ⁇ l max. and then return to a practically zero value. ⁇ t being the restitution time of the length of accumulated effect wire ⁇ l max, the speed of the effect wire is then worth on average during this time ⁇ t:
  • the length of the section 15 of accumulated wire is of course adjustable by modifying the shape of the cam 24. If the cam 24 rotates at a constant speed, the instants of accumulation and acceleration follow one another regularly.
  • the speed peaks are, as shown in FIG. 14, less narrow, less high and less close together, so that the flames 2 obtained are less significant and further away from each other.
  • the cam 24 has a variable and random speed so that the distance between the speed peaks and therefore the distance between the flames 2 varies randomly, as shown in FIG. 15.
  • This random variation in speed is based on a program that generates random numbers. These numbers determine, by means of an appropriate electronic system, the speed at the outlet of the motor 23.
  • the axis 20 of the cam 24 or the cams 24 is perpendicular to a vertical plane passing through the section 15 of effect wire, the cam or cams 24 being driven rotating in the same direction as the direction of supply of the effect wire 4.
  • the axis 20 of the surface of revolution 18 of the cam 24 is included, as shown in FIG. 16, in a plane passing through the section 15 of the effect wire, guide means 21 then being provided to maintain said section 15 of wire in the above-mentioned plane.
  • the surface of revolution 18 can also, as shown in FIG. 17, be cylindrical and include means 22, constituted by grooves made in the cylinder, for guiding the section 15 of effect yarn on this surface to move its area of contact 19 with the surface along the axis of the cylinder.
  • FIG. 18 Another variant of surface of revolution 18 is illustrated in FIG. 18.
  • This surface is constituted by a profile formed in a hollow cylinder driven in rotation about its axis 20, a guide 21 being provided to maintain the section of wire 15 relative to audit profile.
  • FIG. 19 shows a device in which one acts on one of the two effect wires 4, 4 ′ entering into the composition of the wire 1.
