Definitions

  • the invention relates to a leno thread delivery device for a weaving machine, with at least one thread supply spool pair.
  • the invention has for its object to provide a particularly improved in this regard device.
  • the invention resides in a spring tensioner, from which the thread release is controlled as a function of the thread tension. This makes it possible to keep the pulled leno thread constantly under a desired thread tension. The thread cannot sag more and get caught on any part of the machine. For this reason, web operations can no longer be disrupted.
  • the weaving machine 1 contains two machine cheeks 2, 3 in which the main shaft 5 driven by a motor 4 is mounted.
  • the weft thread 6 is drawn off from a stationary bobbin 8 by means of a projectile 7 and inserted into the shed.
  • the projectile is shot down by a shot 9 and caught in a catch 10.
  • the shafts are denoted by 11, the reed by 12.
  • the fabric 13 is wound onto a fabric tree 14. It contains 15 lathe, e.g. Twist or half-twist bindings. These are generated by leno thread delivery devices 16, which are indicated schematically in FIG. 1.
  • Each leno thread delivery device is fastened on a support 17 connected to the weaving machine frame and contains a base plate 18.
  • a drive shaft 21 for the leno thread delivery device 16, which rotates continuously during operation, is accommodated in the stay 17.
  • a pinion 22 which meshes with two gear wheels 23.
  • Each gear wheel 23 is seated on an axis 25 which is rotatably mounted in the base plate 18 and carries a disk 26 at the top.
  • leno thread supply bobbins can be attached to these, only one of which is shown in FIGS. 2 to 5 and designated 29.
  • the discs 26 visible on the right in FIG. 2 are driven via their gear wheels 23 and an intermediate gear wheel 31. This is in engagement with the gear 22.
  • a thread guide tube 33 (Fig. 3.5) is coupled for rotation, through which the pair of threads 45, 46 coming from the two associated bobbins 29 are derived downwards in Fig. 3.5 and e.g. is fed to a twister disc and then fed into the weaving machine.
  • each disc 26 in addition to each ratchet wheel 27 or the associated spool 29, an axle 35 is fastened, on which a control lever 37 provided with a thread eyelet 36 and a pivot lever 40 provided with a thread eyelet 38 and a curved slot 39 are rotatable and supported one above the other.
  • the pivot lever 40 has at its rear end a pawl 41 which cooperates with the ratchet wheel 27.
  • the control lever 37 has a bolt 42 which projects into the slot 39 of the associated pivot lever 40.
  • the four disks 26 are removed from the Drive shaft 21 is continuously rotated in accordance with arrows 43 (FIG. 2), so that a pair of coils 29 belonging together and arranged on one and the same disc 26 rotates around a thread eyelet 44 arranged at the upper end of the thread guide tube 33.
  • the leno thread drawn off from the bobbin denoted by 29a in FIG. 4 is shown continuously and with 45, the thread drawn off from bobbin 29 is shown in broken lines and denoted by 46.
  • the coils 29 and 29a rotate in FIG. 4 according to the arrows 47, 48.
  • the threads 45, 46 are drawn off according to the arrows 49, 51 and run downward through eyelet 44 and, according to arrow 52, through the thread guide tube 33 in FIG. 5 to the weaving machine.
  • the axis 35 continues in FIG. 5 at the top into a threaded bolt 61, on which the adjusting nut 54 can be rotated and locked with a nut 62.
  • the upper end 63 of the spring 55 is anchored in the nut 54.
  • the tension of the spring 55 can thus also be set to a desired level during weaving operation.
  • the leno thread delivery device can be used, for example, as a full twist (twist) device.
  • the yarn guiding pipe 33 is a twisting disc nachzupause but it can also be combined with a Halbcardervorrich - used tung.
  • a leno cord suspended in the shafts 11 of the weaving machine 1 must be connected downstream of the thread guide tube 33.
  • the drive 21, 23 of disk 26 is omitted in this case, cf. Fig. 7.
  • the device contains e.g. on the base plate 18 only two disks 26 with associated pairs of coils 29, 29a.
  • the lower spring action of the pivoting movement of the control lever 37 can also be used to ensure that the differences in length of the leno threads 45, 46 occurring during the rotation of a downstream twisting disc or during the up and down movement of the shafts 11 are absorbed and the leno threads are constantly under the same Tension can be kept.
