Definitions

  • the device has several rotary rings against which the filament must be applied so as to be driven in rotation by the inner edge of the said rotary rings to undergo twisting.
  • These rotary rings being staggered along a rectilinear path and distributed in two groups, which overlap so that in following the rectilinear path there is encountered alternately a ring of one group and a ring of the other group.
  • These two groups can undergo relative displacement in a plane perpendicular to the rectilinear path.
  • the rings of the two groups are urged against a single drive roller driving the said rings, and the relative displacement of thetwo groups is effected by pivoting around the ads of this single drive roller.
  • the invention relates to twisting devices for filaments (that is to say for fine threads), especially for textile filaments, comprising several rotary rings against which the filament must be applied so as to be driven in rotation by the inner edge on the said rotary rings to undergo twisting.
  • such devices comprise rotary rings staggered along a rectilinear path and distributed in two overlapping groups, so that by following the said rectilinear path there will be encountered alternately a ring of one group and a ring of another group.
  • this drive mechanism prevented dismounting and remounting of the rings from preceding easily.
  • the twisting device is characterised by the fact that the rings of the two groups are held urged against a single drive roller driving the said rings, and by the fact that the relative movement of the two groups is effected by pivoting around the axis of this single drive roller.
  • the rotary drive'mechanism of the rotary rings of the two groups is extremely simple, since it comprises neither belt, nor pulley, is of small bulk, and well adapted to high rotary speeds.
  • this mechanism does not comprise any element'which constitutes anobstacle or impedes dismounting and remounting of the rings.
  • twisting device (heater or cooler) followed or preceded by the twisting device. It is advantageous to arrange the twisting device so that the rotary ring situated just after or just before the fixing device has its inner edge tangential to the axis of the setting device two groups of rotary rings are in their active position.
  • the invention also relates to textile filaments obtained by textile machines equipped with the abovedefined twisting devices.
  • FIG. 1 is a diagrammatic view in perspective of a twisting device according to the invention and showing the inactive position of tis two groups of rotary rings;
  • FIG. 2 shows, under the same conditions, the twisting device shown in FIG. 1, but for the active position of its two groups of rotary rings;
  • FIG. 3 shows, by a more detailed side view, a particular embodiment of a twisting device according to the invention, the two groups of rotary rings of this device being shown in their inactive position.
  • FIG. 4 shows, under the same conditions, the twisting device shown in FIG. 7, the two groups of rotary rings of this device occupying this time their active position;
  • FIG. 5 is an end view of the embodiment shown in FIG. 3;
  • FIG. 6 is an end view of the embodiment of the twisting device shown in FIG. 4; and, lastly,
  • FIG. 7 is a partial diagrammatic cross-section on a large scale of one embodiment of a twisting device according to the invention.
  • FIGS. 1 and 2 there is shown diagrammatically a twisting device interposed between a setting device 1 and a delivery device 2 of a machine for texturizing a filament 3.
  • This twisting device comprises several rotary rings, denoted by the reference numeral 4 modified by an index a or b as explained below.
  • These rotary rings are actuated by a rotary movement in the same. sense and at the same speed or at different speeds, and the filament 3 must be applied against the said rotary rings so as to be driven in rotation by their inner edge to undergo twisting.
  • rotary rings are staggered along a rectilinear path which the filament 3 would follow in the absence of the abovesaid rings, that is to say a rectilinear path extending from the setting device 1 to the deliverydevice 2.
  • the rotary ring adjacent to the setting device is arranged with its inner edge tangential to the axis of the setting device.
  • These two groups A and B can undergo relative displacement, in.a plane perpendicular to the rectilinear path, to pass from an inactive position, in which the rotary rings 4a, 4b of the two groups A and B encircle with spacing from the rectilinear path of the filament 3 (FIG. 1), to an active position, in which the rotary rings 4a, 4b of the two groups A and B come intocontact with the filament 3 and oblige it to follow a sinuous path which the filament 3 is applied against the said rotary rings 4a, 4b so as to be driven in rotation by their inner'edge to undergo the desired twisting (FIG. 2).
  • means are provided to adjust the amplitude of the relative displacement undergone by the two groups A and B, which has the effect of adjusting the value E of the overlap of the rings 4a of the group A with respect to rings 4b of the group B.
  • the angle can be adjusted which determines the sinuous path of the filament 3 in the course of its progress in the rings 40, 4b, and the arc of contact 0' 1r/2 0 of the filament 3 on the rounded portion R of the inner edge of each ring 4a, 4b (FIG. 7).
  • the rings 4a and 4b are held supported on a single drive roller 5 which is in engagement with a tangential belt 7 and which drives the said rings.
  • the relative displacement of the two groups A and B is effected by pivoting around the axis of this single drive roller 5.
  • FIGS. 1 to 6 there is shown a device which comprises a fixed group A with two rotary rings 4a, and a mobile group B with a rotary ring 412.
  • the twisting device it is advantageous to arrange the twisting device so that the fixed group A has a rotary ring 4a situated just after the setting device 1, and that this ring 4a has its inner edge at atangent to the axis of the setting device 1.
  • FIGS. 3 to 6 shows a twisting device of which the rotary rings 4a, 4b are driven by a drive roller 5.
  • This drive roller 5 is itself driven by the tangentialbelt 7 and it comprises drive discs 8 cooperating respectively with the two rings 4a of the fixed group A .and with the ring 4b of the mobile group B.
  • each of the abovesaid rings 4a, 412 comprises a groove 9 in which the corresponding drive disc 8-becomes positioned and depending on the diameters of the grooves 9 in the rings and the diameters of the drive discs 8, the rings may be driven with the same or with'different speeds.
  • Each ring 4a, 4b is held against this drive disc 8 by means of two rollers 10 borne by a fixed support 110 when it relates to two rings 4a of the fixed group A, and by a mobile support 1111 when it relates to the ring 41) of the mobile group B.
