Definitions

  • the invention relates to a texturing machine for false twist texturing of a thread according to the preamble of claim 1.
  • a generic texturing machine is known from EP 0 853 150.
  • a supplied plain yarn is textured by a false twisting process.
  • the false twist generated by a false twist unit is fixed in the thread by a heat treatment and a subsequent-sequential cooling.
  • a cooling tube is used, on the surface of which the thread is guided helically.
  • the known texturing machine has movable thread guides which change the casserole or run-off point of the thread relative to the circumference of the cooling tube.
  • a change in the yarn guide has the fundamental disadvantage that the upstream in the yarn course or downstream treatment facilities must be included in the changed thread guide.
  • the cooling tube is designed to be movable, so that the length of the cooling section on the circumference of the cooling tube by a movement of the cooling tube is changed
  • the thread guides the special conditions of pretreatment or treatment.
  • This allows stronger deflections on the thread both at the inlet and outlet from the cooling device as well as within the cooling device avoid.
  • the cooling tube can be adjusted by turning, swiveling or wobbling movements, so that the circumferentially guided thread can be guided with more or less wrap.
  • the cooling tube is held by an adjustable holding device, by which the relative position between the outlet end and the inlet end of the cooling tube is changeable.
  • one of the ends of the cooling tube can be kept substantially unchanged in the position, which simplifies the connection of a cooling fluid supply in particular
  • the movements required for the change in length of the cooling section are thus carried out substantially with the not connected to the cooling fluid supply end of the cooling tube.
  • the holding device is equipped according to an advantageous development with a guide means by which the outflow end of the cooling tube relative to the sesfadenixie is feasible and lockable.
  • the cooling tube could be moved by pivoting the drain end relative to the drain guide in a simple manner.
  • the flow guide is attached to the circumference of the cooling tube to change the length of the cooling section in this case the cooling tube is guided by rotation about the acting as a fulcrum guide thread through the guide means.
  • the movement of the cooling tube required for the change in length can also advantageously be formed by the inlet end of the cooling tube according to the developments according to claims 6 and 7.
  • the movement of the cooling tube can preferably be stirred by an actuator, so that an equal adjustment of the length of the cooling section is present in each processing point.
  • the inlet thread guide and the outlet thread guide or only one of the thread guides can be made adjustable.
  • a processing station includes at least a first delivery mechanism 5, a heater 6, a cooling device 7, a false twist unit 16, a second delivery mechanism 15 and a winding device 17, wherein the processing units are arranged in sequence to form a threadline.
  • a thread 1 is withdrawn from a supply spool 2 by the first delivery mechanism 5.
  • the supply spool 2 is mounted on a mandrel 3 of a gate (not shown here).
  • the first delivery mechanism 5 guides the thread 1 into the so-called false-twist zone, which extends as far as the false-twist unit 16.
  • a false twist is generated in the thread 1, which runs back within the false twist zone in the thread and thereby fixed in the heater 6 and the subsequent cooling device 7.
  • the second delivery mechanism 15 the thread is subtracted from the false twist unit 16 and fed to the winding device 17.
  • the thread 1 is wound into a coil 18.
  • the cooling device 7 In order to cool the thread 1 within the false twist zone, the cooling device 7 consists of a cooling tube 8, which is connected via a line 10 to a coolant source 9.
  • the cooling tube 8 is at one end an inlet yarn guide 19, which leads the yarn 1 to the cooling tube 8, and assigned at the opposite end of a drain guide 20.
  • the end of the cooling tube 8 in the region of the inlet yarn guide 19 is referred to here as a run-end 21 and the opposite end of the cooling tube 8 as a drain end 22.
  • the supply of the coolant via the leading end 21, which is connected by the line 10 to the coolant source 9.
  • the inlet yarn guide 19 and the drainage yarn guide 20 are mounted separately from the cooling tube 8 fixed to a machine frame, not shown here.
  • the cooling tube 8 is held by the holding device 11 between the inlet yarn guide 19 and the drain guide 20.
  • the holding device 11 has a holder 12 in the region of the run-up end 21 and a guide means 13 in the region of the discharge end 22.
  • the cooling tube 8 is held in the holding device 11 in such a way that the thread 1 is helically formed on the circumference of the holder Cooling tube 8 is guided from the end of run 21 to the outlet end 22.
  • the degree of wrap or the pitch angle of the helix on the circumference of the cooling tube 8 determines the length of the cooling section, in which there is a contact between the thread 1 and the cooling tube 8. At a constant yarn running speed, a cooling effect determined by the length of the cooling path is thus generated on the yarn 1.
  • the cooling tube 8 in the holding device 11 can be released from a fixing and move such that the length of the cooling section is larger or smaller, i. that the wrap of the thread on the circumference of the cooling tube 8 is increased or vice versa.
  • Fig. 2 the holding device 11 and the cooling tube 8 are shown schematically in different views.
  • a plan view is shown in FIG. 2.1
  • a front view is shown in FIG. 2.2. Only the relevant components of the cooling tube 8 and the holding device 11 were shown. Unless an explicit reference is made to one of the figures, the following description applies to both figures.
  • the leading end 21 of the cooling tube 8 is held in the holder 12 movable.
  • the drain end 22 of the cooling tube 8 is held in the guide means 13.
  • the guide means 13 is formed with a holder 25 receiving the cooling tube 8.
  • the holder 25 has a circular guide contour 26.
  • the guide means 13 is aligned with the guide contour 26 to the flow guide 20 such that theticianfadenschreiber 20 is aligned eccentrically to the guide contour 26.
  • the position of the thread guide 20 always remains the same.
  • the Cooling tube 8 can thus turn around in a cone shape around the drainage guide 20.
  • a plurality of fixing means 14 are provided; by which the drain end 22 of the cooling tube 8 can be held in any position within the holder 25 on the guide contour 26.
  • the drain end 22 is guided around the drain guide 20 in the holding device 11.
  • the opposite run-end 21 of the cooling tube remains essentially unchanged in its position. The evasive movements are absorbed by the holder 12.
  • the configuration of the holding device and in particular the embodiment of the guide means 13 is exemplary.
  • FIG. 3 another embodiment of a cooling device 7 is shown.
  • the cooling tube 8 is releasably held in the holding device 11.
  • the drain guide 20 is attached to the outlet end 22 on the circumference of the cooling tube 8.
  • the inlet yarn guide 19 is held stationary on a machine frame.
  • the guide means 13 has a circular cutout 27 with a circular guide contour 26. Within the cutout 27, the cooling tube 8 is arranged such that the flow guide 20 is aligned eccentrically to the guide contour 26.
  • the cooling tube 8 is rotated in such a way around the acting as a fulcrum guide 20, until a desired position or a predetermined length of the cooling section is reached.
  • the rotational movement of the cooling tube 8 is performed within an imaginary envelope 24.
  • the envelope 24 is cone-shaped, the cone tip is formed by a yarn guide 23 at the outlet of the heater 6. This is achieved; that the deflection at the end of run 21 of the cooling tube 8 relative to the inlet yarn guide 19 is low, so that a tangential emergence of the yarn on the circumference of the cooling tube 8 is ensured.
  • the cooling tube is fixed. The fixing means are not shown in FIG.
  • the invention extends not only over the illustrated embodiments. So it is possible to carry out the movement of the cooling tube substantially with the inlet end. The expiration in the position would be kept essentially unchanged. Likewise, the movement of the cooling tube: could be controlled by actuators that approach, for example, a preselected position immediately and keep the cooling tube in the approached position.
  • the achieved by the inventive adjustment of the cooling tube wraps of the thread at the periphery of the cooling tube are substantially in the range of 0 ° and 360 °. However, especially with the embodiment shown in FIG. 3, looping> 360 ° could be achieved.
