Definitions

  • the thread regulators proposed to date are generally in the form of a rotary device constituted by two cups between which the thread passes. These cups are mounted on a hub and are generally locked against each other by means of a nut allowing their pressure to be adjusted and consequently the tension which they allow to communicate with the wire.
  • the hub is friction mounted on a rotary shaft common to all positions on the same face of the machine. To achieve the relaxation of the wire, it is essential that the speed of this device is greater than the speed of movement of said wire, so that it will tend to rest on the cups while bracing on a circular arc.
  • Such a device is very widely used to date but has the disadvantage of posing problems when launching the wires, given that they can get caught in the deliverers during the various manipulations required by such an operation.
  • such holding devices can only be used for a single wire and only provide a single holding action on the path of the wire.
  • Such a device can either allow two wires to be treated from two neighboring positions, the central cylindrical track being used during launching and each wire being pushed back on the two lateral tracks formed by the pairs of cups after start-up, or to ensure two successive detention operations on the route of the same wire.
  • the central cylindrical track is constituted by a part interposed between the two hubs and is held by means of screws, the drive by the drive shaft being transmitted by a seal; in such a case, this track has a diameter greater than the outside diameter of the cups and it has two peripheral edges making it possible to maintain the wire or wires during the launching operation.
  • the central track is produced in the hub itself, forms an integral part of it, and its outside diameter is less than the diameter of the lateral edges of the cups which therefore make it possible to ensure positioning and maintenance of the wire or wires when they are in contact with this central track and serve as a ramp allowing the wire or wires to be transferred between the cups after launch.
  • the wire tensioner device essentially consists of an assembly mounted integral with a motor shaft (1).
  • This assembly designated by the general reference (2) consists of two pairs of cups respectively (3, 4) and (5, 6) mounted on two hubs (7.8).
  • Each of these pairs of cups constitutes, in known manner, a wire holding device.
  • the nuts (9,10) mounted on the hubs make it possible to adjust the pressure between the cups (3, 4) and (5, 6) and therefore to adjust the tension that is communicated to the wire.
  • the two sets of cups are mounted on either side of a circular track (11), constituted in this case by an insert between the two hubs (7, 8).
  • the hubs (7, 8) and the track (11) are joined together by means of screws (12, 13) and the assembly is rotated by the shaft (1) by means of a seal. (14).
  • the circular track (11) is smooth, has an outside diameter D greater than the diameter d, of the contact circle between the cups but also the outside diameter d 2 of said cups (3, 4) and (5, 6).
  • two flanges (15, 16) are provided which make it possible to maintain the wire on the circular track (11) during the launching operation.
  • FIG. 2 illustrates a second embodiment of a device according to the invention, device in which the same references are used to designate the elements identical or equivalent to those forming the subject of the first embodiment described above.
  • the central circular track (11) is formed directly in one of the hubs, (7) in the present case, the two hubs (7, 8) also being assembled by means of screws (12, 13) and mounted on the shaft (not shown) by means of a seal (14).
  • the diameter D of the track (11) is between the diameter d, of the contact circle between the cups (3, 4) or (5, 6) and the outside diameter d 2 of said cups.
  • edges (4a) and (5a) of the cups (4) and (5) make it possible to maintain the wire on the track (11) during the launching operation and serve as a ramp facilitating the transfer of said wire between the cups (3, 4) and (5, 6) when launching is carried out and the wires are placed under normal working conditions.
  • Such thread holding devices can be used for any single or double twist twisting textile material, either to ensure the relaxation of two threads working on two successive positions, or to ensure two successive detentations on the same thread when several operations are performed continuously, for example a twisting operation followed by a heat treatment, a twisting operation followed by a false twisting treatment.
  • FIGS. 3 and 4 illustrate such possibilities, it being understood that other applications could be envisaged for such a device, for example on installations making it possible to carry out only heat shrinkage treatments on a wire. , on texturing machines by false twist or the like and, in general, in all cases where it is desired to modify the tension communicated to a thread during a treatment.
  • the regulator (2) makes it possible to treat two wires from two neighboring positions, one passing between the cups (3) and (4), the second between the cups (5) and (6).
  • the two wires from the two neighboring positions are positioned on the central track (11) that such a pressure regulator comprises and, when launching is carried out, the wires are pushed back onto the tracks (3, 4) and (5, 6 ) in order to get into working conditions.
  • such a wire expander device (2) can also be used in the case of a double-twist machine enabling heat treatment to be carried out following the twisting operation.
  • a double-twist machine enabling heat treatment to be carried out following the twisting operation.
  • Such a machine is the subject in particular of French patent 2,430,991 and will not be described in detail.
  • the difference is essential ment in the presence of an oven (32) for the thermal treatment of the wire after twisting.
  • the twisted wire (24) passes through the barbin (25) then around the deliverer (2) according to the invention, before being introduced inside the oven (32).
  • the outlet of the oven (32) it is sent via guides (33, 34) to be brought by means of reels (26, 27, 28).
  • the expansion device (2) is arranged above the double twist spindle. The wire coming from the double twist spindle passes over one of the tracks, for example the track formed by the cups (3, 4) then, after passing through the oven (32), it is brought so as to pass over the second track (5, 6).
  • detentions can also be adapted by varying the pressure exerted by the nuts (9, 10) on each of the respective tracks formed by the cups (3.4) and (5, 6).
  • the wire is placed on the central cylindrical track (11) then, after launching, the turns of the wire are pushed back respectively on the tracks (3, 4) and (5, 6), in order to be able to get into the work situation.
  • Such a device can be used in many fields and in particular on any single or double twist twisting material in which the thread will have to undergo other simultaneous or continuous treatments with the twist, for example a heat treatment, a texturing treatment, or even the addition of a second thread ..
