Definitions

  • the present invention relates to a flyer wing with two wing arms and a closed guide channel for a roving comprising a rectilinear guide tube, which is guided at a spinning position of a roving machine from a drafting system through the guide channel via a press finger, which is at its free End has a yarn guide.
  • a spinning wing is known from British Patent Specification No. 380 745, at. which two wing arms are formed by steel tubes and which has two additional auxiliary arms. The lower ends of these four arms are stiffened by a horizontal ring. From the point of view of strength, this wing can achieve high rotational speeds. In this spinning wing, however, no press finger is provided, so that the roving is deposited on the sleeve in an uncontrolled manner and therefore takes place with insufficient accuracy. In addition, the channel for the roving is partially open, which is disadvantageous for the quality of the roving.
  • the horizontal ring adds noticeably less weight to the flyer wing than must be added to reinforce the wing arms if the horizontal ring is omitted. Due to the fact that the guide tube has no supporting function, there is a further advantage that it is made of any desired material, e.g. also partially
  • OI- ' can be made of ceramic.
  • Fig. 2 is a horizontal section at the location of line II-II of Fig. 1 in an enlarged view.
  • the flyer wing shown in Fig. 1 has a hollow cylinder 12 provided with a bore 11, which is rotatably mounted in a bearing, not shown.
  • An arm part 14 having a tubular feed channel 13 extends from this cylinder 12. Together with a vertical arm part 15, which is not visible in FIG. 1 but shown in FIG. 2, it forms the one wing arm as a fixed unit 14.15 of the flyer wing.
  • a second wing arm 16 also extends from the hollow cylinder 12 and consists of an oblique and a vertical part.
  • the lower ends of the arm 14, 15 and the arm 16 are assembled with a horizontal ring 17.
  • the arm 16 is firmly connected to the ring 17 by means of a screw 18, but, any type of fastening, such as e.g. casting in one piece is possible in the context of this invention.
  • a guide tube 22 is from an upper pivot bearing 20 and carried by a lower pivot bearing 21.
  • the upper Schwen camp 20 is attached to the arm part 14.
  • the lower pivot bearing 21 is installed in the ring 17.
  • the bearings 20, 21 are arranged with respect to the guide tube 22 in such a way that the tube 22 is pivoted about its longitudinal axis 23.
  • the feed channel 13 advantageously has a short tubular extension which extends into the guide tube 22 to form the upper bearing 20.
  • a press finger 25 is firmly connected to the guide tube 22. At its free end it has a yarn guide 26 for the roving, which is provided with an eyelet 27.
  • a bent tube 30 forms a continuation of the guide tube 22. Its free end is directed towards the roving guide 26.
  • the bore 11, the feed channel 13, the guide tube 22 and the bent tube 30 together form a guide channel for the roving formed during operation of the flyer wing.
  • the tube 30 is attached to the press finger 25 in the example shown.
  • a spindle (not shown) is provided for each spinning station, the axis of rotation of which coincides with the axis of rotation 31 of the corresponding flyer wing.
  • a prestressing element formed by a helical spring 32, the guide tube 22 and thus the press finger 25 fixed with it is in the direction against the axis 31, i.e. against the spindle, not shown, subjected to a permanent pretension.
  • the guide tube 22 is also connected to a counterweight 33, which is also pivotable with the guide tube 22 about its longitudinal axis 23.
  • the counterweight 33 is subjected to an outward centrifugal force. This generates a torque which is opposite to that generated by the press finger 25.
  • the press finger 25 is pressed against the spindle in the same direction of rotation by the counterweight 33 as is the case by the coil spring 32.
  • the torque generated by the counterweight 33 and the pretension generated by the spring 32 endeavor to rotate the guide tube 22 in the clockwise direction according to the view in FIG. 2.
  • a stop member 34 serves to limit such a movement. In the example shown, it is designed as a screw which is attached in the arm part 15. By turning the screw 34, the one end position of the pivoting of the press finger 25 can thus be set as desired.
  • the fiber sliver is guided by a drafting system, not shown, through the guide channel which, as already mentioned, comprises the bore 11, the feed channel 13, the guide tube 22 and the bent tube 30.
  • a roving is present, which, mentioned means of the Pres' sfingers 25 concentric to the axis 31 in the previous by rotation, unreported ⁇ drawn spindle is wound up as roving.
  • the spindle is also subjected to continuous rotation about its own axis, which is identical to the axis 31. In addition, it is moved up and down relative to the flyer wing.
  • the press finger 25 is constantly against the spindle, or a sleeve attached to it pretensioned, or pressed against this, and puts on this roving turns to form a winding. It should be noted at this point that in the patent claims the simpler expression is used because of the expression "roving", although it is a spinning process in which immediately after leaving the drafting system, ie before entering the bore 11, a one determines roving having twist is not yet present.
  • the flyer wing according to the invention has the further advantage that the roving rotating about the axis 31 is in practically the entire part of its path during the spinning process in a closed channel and thus there is practically no blown fibers due to the extraordinarily high rotational speeds is.
  • the flyer wing according to the invention is very advantageous if it is used in a machine with automatic bobbin change, in which the roving bobbin is removed upwards and the new, empty sleeve is inserted again from above.
  • the flyer wing in these machines is inclined in such a way that the plane defined by the arms 14, 15 and 16 reaches an inclined position relative to the spindle axis. Thanks to the fact that, due to the spring 32, the pressing finger 25 is in contact with the winding of the bobbin even when the wing is at rest, when the bobbin is moved upward, the roving between the eyelet 27 and the winding is separated with great reliability and at the desired location.
  • the permanently pre-tensioned or pressed-on pressing finger 25 a secure grasping of the roving end or sliver beard held by the eyelet is ensured by the newly placed sleeve.

Abstract

Les extremites libres des bras (14, 16) du flyer sont solidarisees par un anneau (17). Un conduit-guide ferme comprend un tube (22) pour la meche, qui peut pivoter autour de son axe et qui porte un doigt presseur (25). On obtient ainsi un flyer leger de haute resistance qui permet des vitesses de rotation elevees. Le conduit-guide pour la meche peut etre ferme sur la majeure partie de sa longueur.
