Definitions

  • the invention relates to devices for assembling threads, in particular textile threads.
  • a thread should be taken in a very general sense.
  • a thread may be a "single thread” constituted for example by one or more filaments.
  • the single thread is made up of a single filament it is called “monofilament” and when the simple thread is made up of several filaments it is called “multifilament”.
  • a wire can itself be a set of single wires.
  • Such an assembly is called “twists” when it is constituted by several simple wires joined together by a single twisting operation, and such an assembly is called “wired” when it is constituted by several wires, at least one of which is a twisted , joined by one or more twisting operations.
  • the invention relates in particular to devices which make it possible to assemble at least two wires by first giving a twist to each of the wires, separately, in the same direction, then by twisting these wires together in opposite directions to obtain an assembly. .
  • Known devices of this type generally use rotating disks as described for example in FR-A-2 263 315 and lead to the following drawbacks: high thread tension; high inertia of the devices.
  • the object of the invention is to remedy these drawbacks.
  • the invention also relates to a method for assembling at least two wires.
  • FIG. 1 shows a device 100 according to the invention.
  • This device 100 comprises two coils 1, 2. On the coil 1 is wound the wire 10 and on the coil 2 is wound the wire 20. Each of these wires 10, 20 is constituted for example by an untwisted multifilament.
  • the device 100 comprises a drum 3 and a motor 4 capable of driving the drum 3 in rotation about the axis xx ′ which is for example vertical, FIG. 1 being a section made along this axis.
  • the drum 3 has two ends: the upper end 5 and the lower end 6.
  • first coil coil 1; “First wire”: wire 10; “Second coil”: coil 2; “Second wire”: wire 20; “Wall”: drum 3.
  • the coil 1 is placed outside the drum 3 and the coil 2 is placed inside the drum 3.
  • the coil 2 is arranged inside a pot 7 provided with a cover 8, this pot 7 being itself disposed inside the drum 3 while being devoid of contact with the internal face 9 of the drum 3 , that is to say that the coil 2 has no contact with this face 9.
  • the coil 2 is disposed on the bottom 11 of the pot 7.
  • This coil 2 comprises a mandrel 12, around which the wire 20 is wound, and inside the mandrel 12 is a hollow cylinder 13 which is part of a regulating system 14 for the wire 20, this regulating system 14 being described in more detail later.
  • the drum 3 is connected at its lower end 6 to a plate 15, the assembly of the drum 3 and the plate 15 forming an enclosure 16 in the shape of a bell whose plate 15 constitutes the bottom, the pot 7, with the coil 2 and the system 14 being located inside this bell 16.
  • This bell 16 rotates around the axis xx ′.
  • the device 100 comprises means either for immobilizing the coil 2 during the rotation of the drum 3, or for giving this coil a rotation independent of that of the drum 3. These means are as follows.
  • the bottom 11 of the pot 7 is integral with a cylindrical bearing 17, of axis xx ′, this bearing being of the ball bearing type. This bearing 17 can rotate around a cylindrical piece 18 secured to the plate 15.
  • This piece 18 is also secured to the hollow spindle 19 which is itself secured to the drive cylinder 21 of the motor 4.
  • a magnet 22 On the pot 7 is fixed a magnet 22.
  • this magnet 22 In front of this magnet 22 is arranged another magnet 23, the drum 3 being disposed between these two magnets 22, 23 which have no contact with the drum 3.
  • the assembly 24, comprising the bell 16, the part 18, the spindle 19 and the cylinder 21, is driven in a rotating part by the motor 4, around the axis xx ′, and therefore constitutes a rotating assembly.
  • the assembly 25, comprising the pot 7 with its cover 8, the bearing 17, the coil 2, the mandrel 12, the regulator system 14, the magnet 22, is stationary relative to the axis xx ′, during rotation of the rotating assembly 24, if the outer magnet 23 is fixed, or rotates around the axis xx ′, independently of the rotation of the rotating assembly 24, if the outer magnet 23 is rotated around the axis xx ′, this thanks to the presence of the bearing 17.
  • the drum 3 and the pot 7 are made with materials permeable to the magnetic field, to allow attraction between the magnets 22, 23, these materials being for example plastics .
  • the operation of the device 100 is as follows.
  • the wire 10 coming from the reel 1 is braked by a regulating system 26 which allows the tension adjustment of the wire 10, this system 26 being constituted for example by two rollers 27, 28.
  • the wire 10 then passes through a fixed guide 29 called "Upstream guide” disposed above the drum 3, this guide 29 being a circular eyelet of axis xx ′.
  • This guide 29 allows the wire 10 to enter the drum 3 through the upper end 5 of the drum 3.
  • the wire 10 passes through the drum 3, outside the pot 7 and exits through the guide 30 secured to the bell 16, this guide 30 being for example an eyelet disposed in the plate 15.
  • the eyelet 30 is disposed in the vicinity of the lower end 6 of the drum 3.
  • the wire 10 thus passes through the drum 3 from the upper end 5 to the lower end 6 in the direction of the arrow F10.
  • the wire 10 then passes over a movable guide 31 called “downstream guide” disposed outside the bell 16 and under this bell, in the vicinity of the axis xx ′, this downstream guide 31 rotating in the same direction and at the same angular speed. that the drum 3.
  • This downstream guide 31 is constituted by a roller 32 whose axis 33 is integral with the hollow spindle 19 which supports the plate 15.
  • the wire 10 driven by centrifugal force, is pressed against the internal face 9 of the drum 3 by turning integrally with the drum 3 around the pot 7 and therefore of the coil 2, without there being contact between the wire 10 on the one hand and the pot 7 and the coil 2 on the other hand.
  • the wire 10 is therefore twisted in the same direction as the rotation of the drum 3 between the upstream guide 29 and the downstream guide 31, the wire 10 thus becoming the twisted multifilament 10T.
  • the wire 20 delivered by the coil 2 passes through the regulating system 14.
  • This system 14 comprises the cylinder 13 in which the cups 34 are arranged.
  • the wire 20 enters the cylinder 13, through the upper end 35 of this cylinder, and it then passes successively through the cups 34 whose axes are integral with the cylinder 13.
  • These cups 34 are each constituted, in a known manner, by two discs with springs which apply the discs to the wire 20 disposed between them, so as to be able to apply an adjustable braking force to this wire 20, and therefore adjust the tension of the wire 20.
  • the wire 20 then passes through the guide 36, called the "upstream guide", constituted by an eyelet disposed in the bottom 11 of the pot 7, the axis of this eyelet 36 being the axis xx ′.
  • the wire 20 then leaves the drum 3 and passes over the movable guide 37, called the “downstream guide”, placed outside the bell 16 and under this bell in the vicinity of the axis xx ′.
  • the progression of the wire 20 is shown diagrammatically by the arrow F20.
  • This downstream guide 37 rotates in the same direction and at the same angular speed as the drum 3.
  • the wire 20 is twisted in the direction of rotation of the drum 3 to give the twisted multifilament 20T.
  • the downstream guide 37 of the wire 20 consists of a roller 38 whose axis 39 is integral with the hollow spindle 19.
  • the axes 33, 39 of the rollers 32, 38 are parallel between them and located in the same horizontal plane P, on either side of the axis xx ′, at the same distance from this axis.
  • These rollers 32, 38 are located inside the spindle 19.
  • the direction of movement, along the axis xx ′, of each wire 10, 20 to go from the upstream guide 29, 36 to the downstream guide 31, 37 corresponding to this wire is by definition the direction in which it is necessary to move, along the axis xx ′ to go from a plane passing through the upstream guide 29, 36 to a plane passing through the downstream guide 31, 37 corresponding to this wire, these planes being perpendicular to the axis xx ′.
  • the plane P29 is such a plane passing through the upstream guide 29 of the wire 10
  • the plane P36 is such a plane passing through the upstream guide 36 of the wire 20
  • the plane P is such a plane passing through the downstream guides 31, 37 , these planes P29, P36, P being represented by line segments in FIG. 1.
  • the planes P29, P36 are located above the plane P, and therefore the direction of movement along the axis xx ′ to go from the upstream guide 29, 36 to the downstream guide 31, 37 is the same for the wire 10 and for the wire 20 since it is oriented from top to bottom, according to arrow F.
  • the downstream guides 31, 37 are interconnected by the wires 10, 20, all of these guides 31, 37 giving a regulating system 40 which is shown in more detail in FIG. 2.
  • the direction of progression of each wire 10, 20 is represented by the arrow F10, F20 as in FIG. 1.
  • the wire 10 passes over the roller 32 of the downstream guide 31, then then over the roller 38 of the downstream guide 37, to exit the system 40 from of the roller 38.
  • the wire 20 passes over the roller 38 of the downstream guide 37, then then over the roller 32 of the downstream guide 31 to exit the system 40 from the roller 32.
  • rollers 32, 38 are driven in rotation around their axes 33, 39 by the wires 10, 20 which therefore pass in the same direction on each of these rollers, all of these rollers 32, 38 further rotating around the axis xx ′ with the same speed angular as the rotating assembly 24 as previously described since their axes 33, 39 are integral with the spindle 19 and therefore driven in rotation about the axis xx ′ by this pin.
  • the rotation of the roller 32, shown diagrammatically by the arrow F32 is in the opposite direction to the rotation of the roller 38, shown diagrammatically by the arrow F38, the wires 10, 20 therefore having directions of progression F10, F20 crossed between these rollers 32, 38 without that these wires touch between these rollers and on these rollers.
  • the rollers 32, 38 have identical shapes and dimensions, and the ratio d / r is preferably between 1.2 and 4, “d” being the distance which separates each axis 33, 39 from the axis xx ′, and “r” being the outside radius of the rollers 32, 38 (FIG. 2).
  • the twisted multifilaments 10T, 20T emerging from the rollers 38, 32 are then brought together at point A, on the axis xx ′ and they are passed over the roller 42 whose axis 43 is fixed (FIG. 1).
  • These two wires 10T, 20T are therefore twisted together between point A and the roller 42, given the integral rotation of the rollers 32, 38 around the axis xx ′, this twist, called “twist of twists”, having a direction opposite to the rotation of the drum 3.
  • the assembly 44 thus obtained is a twist which passes over the capstan 45 and which is wound on the spool 46, the capstan 45 making it possible to adjust the linear speed of the plies 44 and consequently the linear speed of the wires 10, 20 before their assembly. .
  • the invention allows the following advantages to be obtained compared to known devices with a rotating disc: the tensions of the wires 10, 20 are reduced during their passage through the device 100, before their assembly, this in particular because the wire 10 is pressed against the internal face 9 of the drum 3 during its rotation, instead of rotating freely in the air around coil 2; the regulator system 40 making it possible to adjust the flow rate of the twisted multifilaments 10T, 20T is integral with the spindle 19 and therefore with the rotating assembly 24 of the device 100 and it is rotated by the motor 4.
  • the inertia of this system 40 when the device 100 is started or stopped, it is therefore not collected by the twisted multifilaments 10T, 20T.
  • the voltages of these wires 10T, 20T are therefore reduced on bare start when stopped and the device 100 allows rapid acceleration and deceleration.
  • the fact that the point A of assembly of the twisted multifilaments 10T, 20T is free on the axis xx ′ makes it possible to avoid the use of a guide, for example an eyelet, which eliminates the risks of abrasion at this point.
  • FIG. 2 shows the angles ⁇ corresponding to the twisted multifilaments 10T and 20T.
  • the device 100 is used to make two plies 44, one of which is a ply of aromatic polyamide and the other a ply of rayon, each of these two plies being obtained with two threads 10, 20 which are multifilaments.
  • the characteristics of the multifilaments 10, 20 and of the plies 44 obtained are given in the following table:
  • twists are expressed in number of turns per meter and the letter Z or S which precedes the value of the twist is commonly indicated in the textile industry and means that the twist is carried out in the Z direction (for the letter Z) or in the S direction (for the letter S), the Z direction and the S direction being opposite.
  • the breaking force is expressed in Newtons.
  • the elongation is determined with a force of 250 Newtons for the plied aromatic polyamide and with a force of 50 Newtons for the plied rayon. This elongation is expressed in%.
  • the improvements due to the invention are as follows, starting from the same multifilaments and obtaining the same twists: Twisted aromatic polyamide, The breaking force is increased by 11%, The elongation is reduced by 8%, Twisted rayon The breaking force is increased by 13% The elongation is reduced by 7%.
  • the device 100 according to the invention makes it possible to increase the breaking force and to decrease the elongation, which translates into an increase in the module, and this in a notable manner.
  • the regulator system 14 of the wire 20 is in the form of a cylinder 13 placed inside the drum 3, it is therefore very easy to remove the coil 2, to replace it with another, during the operation of the device 100, and this without having to remove the system 14 which therefore remains permanently, trimmed with wire 20.
  • the device 100 has been described as making it possible to preferably produce a twist from two multifilaments, but this device 100 could be used to make assemblies with threads other than multifilaments, for example starting from at least one thread constituted by a plied to get a cable.
  • the invention is not limited to the embodiments previously described.
  • the regulating system 40 could be rotated about the axis xx ′ by other means than the motor 4, but the use of the motor 4 to rotate both the rotating assembly 24 and the regulator system 40 has the advantage of simplicity.
