Definitions

  • the present invention relates to a method and a device for the fluidal drawing-in of free textile fibre ends through their hollow guides in textile machines.
  • the textile fibre is partially inserted into the guide hollow by its end, which is then axially acted upon by the pressure fluid passing through the hollow, thus performing the drawing-in of the textile fibre through the guide hollow.
  • the device is made in such manner that the pressure fluid is fed from a hand-operated valve which is connected to the pressure fluid source by means of a hose.
  • An embodiment used more frequently has a drawing-in nozzle mounted at the point of the inlet hollow of the guide, which can be adjustable in axial direction.
  • the nozzle with the pressure fluid supply forms part of the weaving machine device.
  • the textile fibre is inserted into the hollow needle of the nozzle, on which the passage opening is very small.
  • the pressure fluid is fed behind the exit and is discharged through the nozzle forms in the passage opening of the hollow needle underpressure by which the end of the textile fibre is drawn into the nozzle. Further, the pressure fluid, acting axially upon the end of the textile fibre, performs the drawing-in of the fibre through the guide hollow.
  • This method is used in pneumatic weaving machines particularly for drawing in the textile fibre through the hollow shaft of the measuring device, in which the hollow shaft forms, together with an arm, a textile yarn guide, of which the hollow is relatively long and indirect.
  • the subject matter consists in that the textile fibre is acted upon by a pressure fluid flow which is guided thereover transversally and directed into the guide hollow from outside.
  • the subject matter of the device according to the present invention consists in that at the point of the exit opening, said device is provided with an adjusting means for transversally adjusting the textile fibre exactly between the outlet opening of the pressure fluid hole and the inlet opening of the hollow of the guide means.
  • the advantage of the method and the device according to the present invention consists in effective and high speed drawing-in of the textile fibre and in very simple handling therewith.
  • the device is mounted externally of the guide and is undemanding both in its design and its manufacture. This results in a shorter textile fibre handling time, and hence also a shorter fall-out of the textile machine operation.
  • FIG. 1 to 4 demonstrate diagrammatically the phases of the method of drawing-in the textile fibre through the guide hollow in the measuring device.
  • FIGs. 5 and 6 an exemplary embodiment of the device for performing the method according to the present invention is shown in side view and in front view with partial section and in Fig. 7, its incorporation into the assembly of the measuring device of the nozzle weaving machine.
  • a hollow guide pipe 2 Upon drawing-in a textile fibre 1 into a hollow shaft and a winding arm, which forms a measuring device of a not represented nozzle weaving machine, a hollow guide pipe 2, the necessary length of the textile fibre 1 is withdrawn from a supply bobbin 3.
  • the textile fibre 1 is drawn across a transversally adjusting means 4 of the device.
  • the transversally adjusting means 4 is formed in the shown embodiment as a transversal surface is transversally located between the outlet opening of pressure fluid hole 5 and a hollow 6 of the guide pipe 2 of the textile fibre 1 in active zone of expanding the pressure fluid.
  • Said adjusting means 4 is formed like a stationary part of the body 10 of the device and serves to adjust transversally that means to fix the position of the textile fibre 1 being pulled over between the outlet opening 5 and the hollow 6 of the guide 2 in active zone of the pressure fluid so that after supplying the pressure fluid through the inlet 11 into the body 10 said pressure fluid flowing out from the opening 5 blows the textile fibre 1 reliably in the form of a loop 7 into the hollow 6 of the guide 2.
  • a pressure fluid begins to flow from an outlet hole 5 into the hollow 6 of the guide pipe 2 and begins to entrain the textile fibre 1, which is positioned transversally thereto, at the point of its measured length.
  • the textile fibre 1 begins to form a loop 7, and the pressure fluid acts thereupon most effectively at its transversal face 8. With the forming loop 7 of textile fibre 1 advancing through the hollow 6 of guide 2, its free end is also drawn in until said end leaves the hollow 6 at a point of the depositing surface of a drum 9 of the measuring device.
  • a body 10 of the device having a pressure fluid supply 11 is fixed to the stationary part of the measuring device by a pair of screws 12.
  • the supply 11 in the lower part of body 10 is continued by a boring 13, which is deposited at the half of its length on a smaller diameter.
  • a saddle 14 is formed for a spring loaded ball 16 for sealing contact therewith by intermediary of a pressure spring 15.
  • a cover 20 fixed on the body 10 by lock screws 21.
  • the outlet hole 5 is transversally connected therewith and its orifice is situated in front of the hollow 6 of guide 2.
  • the transversally adjusting means 4 for the textile fibre 1 is formed on the body 10 of the device in the form of a transversal surface.
  • the inlet part 22 of the guide pipe 2 is made of anti-abrasive material.
  • the guide 2 and a winding arm (not represented) is mounted in the body of the measuring device rotatably in bearings 23 and coupled in its drive via pulley 24 with the not represented drive of the machine.
  • the size of the outlet hole 5 and the diameter of the hollow 6 in the inlet part of guide 2 are decisive for determining the gap therebetween as, for the correct drawing-in of the free end of the textile fibre 1, the whole carrier current of the pressure fluid must enter the hollow 6.
  • the gap must be only of such size that the cross section of the pressure fluid in the inlet part 22 is at maximum of the same size as the cross section of the hollow 6 of the guide 2.
  • the transversally adjusting means 4 also need not be formed by only one surface, but can be shaped as a groove, an edge or another geometrical formation, which makes possible a transversal adjustment of textile fibre 1 relative to the pressure fluid flow.
  • the device according to the present invention can be either stationary, as specified in the exemplary embodiment, fixed to a stationary part of the textile machine, manually portable, where the outlet hole 5 with the transversally adjustable element 4 for textile fibre 1 is formed in the orifice of a manual pistol, in which the pressure fluid source is formed by a pressure gas cylinder. Between the pressure fluid source and the orifice of the manual pistol, an interrupting dosing valve is interposed.
