Definitions
- a machine has been designed and developed for cabling / twisting and continuous fixing of wires, comprising several treatment stations integrating, in combination and successively, according to the same working position: means twisting / wiring a wire, - heat-fixing means constituted by a rotary heating cup followed by an accumulator capable of cooling and relaxing the wire in the completely free state, without tension, means of winding or winding the wire , said means being subject to drive and wire guide members.
- the twisting / wiring, thermofixing and winding means are mounted in combination with call members of the wire and the arrangements of the frame of said machine, so as to delimit a reduced and compact space integrating the wire unwinding means, along a path of the wire of reduced length.
- the bucket has arrangements suitable for controlling the withdrawal of the wire.
- the bucket has a longitudinal profile delimiting successive zones extending over almost the entire length of said bucket, namely a zone for taking up the initial crimp, a residual shrinkage area and a fixing area.
- the areas of recovery of the initial crimp and residual shrinkage are constituted by conical surfaces, while the fixing zone is constituted by a cylindrical surface.
- the two conical surfaces have different angular values of conicity, the residual shrinkage zone having an angular value lower than that of the zone for resuming the initial crimp.
- the length of the attachment zone is greater than the sum of the lengths of the other two zones.
- the areas of recovery of the initial crimp, residual shrinkage and fixing can be formed by a curved profile.
- Another problem which the invention proposes to solve is to keep the wire in contact with the bucket for a certain time, to secure the wire.
- the heating cup is subject to means able to allow automatic hauling of the wire.
- the accumulator is constituted by a hollow rectilinear body whose end, considered on the side of the outlet, is frustoconical to create, inside said body, a buffer zone slowing down the outlet of said wire in it avoiding going out directly.
- the wire is subjected to the action of bars capable of ensuring a deflection of the wire by giving it the tension necessary for winding.
- the accumulator consists of a relaxation mat where the wire forms a reserve, said mat being disposed between the heat-fixing cup and the winding means, the winding speed being adjusted so that the quantity of wire accumulated in reserve is kept between two predetermined minimum and maximum values.
- the wire is deposited in the accumulator under the effect of a relative movement between a guide element and the accumulator itself. The relative movement is created by a displacement of the wire guide element or by a displacement of the accumulator itself.
- each processing station successively comprises from the unwinding reel: a spindle for twisting and / or wiring the yarn: a pressing delivery device ensuring a limitation of the tension of the yarn and fixing a level of twist downstream; the heated rotary bucket; - the cooling accumulator; the shift bars; the winding or winding reel.
- FIG. 1 is a schematic view showing the principle of processing the wires in the same working position combining the operations of twisting / wiring, heat setting and winding
- - Figure 2 is a perspective view of an embodiment of a machine according to the invention
- - Figure 3 is a schematic view showing an embodiment of the heating cup
- - Figure 4 is a perspective view of the accumulator
- - Figure 5 is a longitudinal sectional view of the accumulator.
- the machine comprises a frame (B) with, preferably, a plurality of identical treatment stations.
- each treatment station integrates, in combination and successively, according to the same working position, twisting / wiring means (1) of a wire, thermofixing (2) and cooling (3) means. wire, and winding or winding means (4) of the wire (5).
- the twisting / wiring (1), heat-setting (2) and cooling (3) means, the winding or winding means (4) of the wire (5) are mounted in combination with arrangements of the frame (B) of the machine, so as to delimit a reduced and compact space integrating the wire unwinding means (6), along a path of reduced length (FIG. 1).
- the twisting / wiring means of the wire are constituted, in a manner perfectly known to a person skilled in the art, by a double twist wiring spindle making it possible to carry out either a twisting or a direct wiring operation.
- the spindle driven by any known and appropriate means receives a coil of a first wire to be treated called "pot wire".
- the spindle has a hollow barrel for the supply of a second wire called "creel wire” coming from the reel of unwinding (6).
- the creel wire is brought through the hollow barrel of the spindle to be joined to the pot wire, at a wiring head (7).
- This wiring head can be combined with a call means making it possible to cancel the tension resulting from wiring or twisting.
- This ground of appeal may be composed of a set of the capstan and pressurized cylinder type. Such arrangements are not described in detail since they are perfectly known to a person skilled in the art. We refer for example to the teaching of patent application FR 2,732,043.
- the means for thermofixing the wire consist of a rotary heating cup (2) followed by an accumulator (3) capable of cooling and relaxing the wire, while being completely free and without tension.
- the bucket (2) is brought to a determined temperature and is positively rotated by any known and appropriate means.
- the heating means can, for example, be of the induction type.
- the bucket (2) has arrangements suitable for controlling the withdrawal of the wire.
- the bucket has a longitudinal profile shaped to define successive and continuous areas extending over almost its entire length. These zones consist of a recovery zone (2a), a residual withdrawal zone (2b) and a fixing zone (2c).
- the two zones (2a) and (2b) are constituted by conical surfaces, while the fixing zone (2c) is constituted by a cylindrical surface.
- the conical bearings (2a) and (2b) have a different angulation.
- the residual shrinkage area (2b) has an angular taper ⁇ less than the taper ⁇ of the initial crimp recovery area (2a).
- the residual withdrawal zone (2b) has a length greater than that of the recovery zone (2a).
- the length of the fixing zone (2c) is greater than the sum of the lengths of the other two zones (2a) and (2b). In the example illustrated, it therefore appears that the three zones (2a), (2b) and (2c) come from a succession of spans of different length and taper.
- the bucket (2) may have a curved longitudinal profile. Given the characteristics of the heating cup (2), it is possible to fix the twisted or cabled wire in order to give it very good crimp characteristics. At the initial crimp recovery zone (2a), the contact of the wire on the heating cup creates a shock effect allowing the wire to regain its initial crimp. This crimping is accompanied by a controlled shrinkage resulting from the conicity ⁇ of the conical aperture (2a). After this shock effect given to the wire, the residual withdrawal zone (2b) allows the wire to complete its withdrawal in a smooth and regular manner since the taper is less than the tapered reach (2b) of length greater than the reach conical (2a).
- the wire is fixed under the conditions to which it was subjected in the two preceding zones. Given the importance of the length of the cylindrical seat (2c), the wire is fixed smoothly.
- the wire retains its original tension but is subject to withdrawal.
- the wire tends to turn on itself as its twist increases.
- all parts of the wire are in contact with the bucket, which ensures a completely round shape to the wire.
- the conical profile and the textile adjustment force the thread to a calculated shrinkage. It is also observed that in order to fix the wire, the latter must remain for a certain time in contact with the different zones of the bucket (2). To increase this contact time, it is known to carry out a wire reeving operation on the bucket. This hauling operation can be carried out manually or automatically.
- the wire is subjected to the action of an accumulator (3) capable of ensuring complete cooling and relaxation of the wire after thermofixing and of creating a buffer zone between the thermofixation and the winding allowing continuous thermofixation when changing the receiving coil (4).
- the accumulator (3) is constituted by a hollow rectilinear body, for example, of quadrangular cross section.
- the end of the accumulator body (3), considered on the side of the outlet, is frustoconical and of gradually decreasing section in the direction of said free end to create, inside the body, a buffer zone slowing down the outlet of the wire avoiding him to go out directly.
- this accumulator (3) at the outlet of the heating cup, is arranged, at the level of the treatment station considered, in a substantially vertical plane, the wire entering through the end (3b) to exit, by simple gravity, at the frustoconical part (3a).
- the accumulator (3) has a series of parallel bars (8) mounted on a support element (9) secured for example to the end of the accumulator (3).
- the bars (8) are arranged substantially perpendicular to the longitudinal axis of the accumulator (3), that is to say perpendicular to the path of the wire, to perform a function of unwinding said wire by giving it the tension necessary for winding.
- the accumulator (3) can consist of a relaxation mat where the wire forms a reserve.
- the mat is placed between the heat-fixing cup (2) and the winding means (4).
- the winding speed is adjusted so that the quantity of yarn accumulated in reserve is kept between two predetermined minimum and maximum values.
- each treatment station successively comprises, from the winding reel (6), according to the same working position delimiting a reduced and compact space with a thread path also of reduced length:
- the delivery presser member (7) ensuring a limitation of the wire tension (5) and fixing a tension level downstream; - the heated rotary cup (2);
