Definitions

  • the invention relates to a weaving machine with a weft supply spool remaining outside the shed during the weft insertion, from which the thread is drawn off during the entry, also with a selvage needle for inserting the weft thread ends located outside the compartment into a following compartment, and with a jet nozzle for Transfer the weft end to the groin needle.
  • the disadvantage of this machine is that the point in time at which other weaving machine operations can take place depends on whether the weft thread is already above the transfer nozzle and it is switched on.
  • the invention has for its object to provide a particularly improved machine in this regard.
  • the invention is characterized by a holding nozzle, which acts on the weft thread before the transfer nozzle is switched on, for holding the weft thread end before transferring it to the selvage needle.
  • the holding nozzle can be used to ensure that the necessary processes, such as e.g. the cutting of the weft thread, regardless of whether the weft thread and the groin needle are already above the transfer nozzle.
  • the weft thread can be fixed in advance by the holding nozzle, so that it e.g. after cutting it can be kept taut and passed over the transfer nozzle and in front of the groin needle.
  • the weaving machine designated as a whole by 31 contains two machine cheeks 32, 33.
  • a goods tree 34 and a reed 35 are arranged in between.
  • the weft 36 is drawn off from a stationary spool 37, passed through a weft brake 38 and blown in from a main entry nozzle 39 located outside the shed 65 (weaving width W).
  • Distributed over the weaving width W are auxiliary nozzles 1 which protrude into the shed 65 during the weft insertion.
  • a suction nozzle 42 is arranged on the catch side 41.
  • the nozzles 39, 1, 42 are e.g. Valves 44 controlled by an electronic control device 43 are connected to an air distribution pipe 45, which is fed via an air supply line 46 from a compressed air container (air source) 47.
  • the container 47 is held under pressure by an air compressor, not shown.
  • blowing nozzle 62a, 62 On the weft side 61 and the catching side 41 there is a blowing nozzle 62a, 62, which is directed upward in FIGS. 1-3 and is fastened on a support 64 which is moved to and fro according to arrow 63.
  • Carrier 64 also contains a holding nozzle 85. While the nozzle 62 passing the weft 36 in FIG. 2 blows from bottom to top (arrow (86)), the holding nozzle 85 blows in the opposite direction from top to bottom according to arrow 87.
  • the air jet from nozzle 62 arrives into a catch channel 88, the air jet from nozzle 85 into a catch channel 89.
  • the shed 65 in which the weft thread 36 is inserted, is formed by the high shed warp threads 66 and the deep shed warp threads 67.
  • edge warp threads 68 by means of which the weft thread ends 36a are held.
  • the carrier 64 with the nozzles 62, 85 is moved from the front, ineffective reversal position according to FIG. 4, which is distant from the reed 35, into a central position shown in FIG. 5, closer to the reed 36.
  • a selvage needle 72 is pivoted counterclockwise about the pivot point 71 according to FIG. 2 (arrow 90) and reaches a central position 72a according to FIG. 5 corresponding to FIG. 6.
  • the tip 73 of the needle 72 contains an eyelet 74, the diameter of which is larger than the diameter of the nozzle 62.
  • the holding nozzle 85 is switched on and then the weft thread 36 is cut off with scissors 77.
  • the weft thread end 36d is thereby blown into the catch channel 89 according to FIG. 6, as a result of which the weft thread 36 is kept taut.
  • the carrier 64 moves into the position shown in FIG. 7 and the selvedge needle 72 into the position 72c shown in FIGS. 7, 9, in which its eyelet 74 is above the transfer nozzle 62.
  • the transfer nozzle 62 is then switched on and the holding nozzle 85 is then switched off.
  • the weft end 36d is thereby from the Channel 89 drawn and directed into channel 88 according to FIG. 9. We blow it through the eyelet 74 and thereby pass it to the groin needle 72.
  • the selector needle 72 is moved to the left in FIG. 10, so that the weft end 36d is inserted into the shed 65 while the selector needle passes through position 74d. It is pulled out of the compartment 65 again, the blown air in the nozzle 62 is switched off, the carrier 64 with the blown air 62 is then again from the rear reverse position (operative position) according to FIGS. 7, 8, 10 into the front reverse position (rest position 4 moves.
  • the auxiliary bar 82 can now be removed.
  • the machine is ready for the weft insertion following the insertion of the weft thread 36c.
  • An insert strip 81 is formed on the fabric 78 and forms the fabric edge.
  • the nozzles 62, 85 are arranged in reverse, i.e. Nozzle 62 in FIG. 2 above weft 36, nozzle 85 below it. Then the transfer nozzle 62 blows in the direction of arrow 87 and the holding nozzle 85 in the direction of arrow 86.
  • the nozzles 62, 85 can also both blow from one and the same side of the weft thread 36.
  • One or both of the nozzles 62, 85 can also be fed with water, for example.
  • the nozzles 62, 85 are arranged directly one above the other, that is to say they have the same axis (they are aligned with one another).
  • nozzle 85 blows against nozzle 62, the thread end 36d being blown into the nozzle 62 used as a catch channel. It is then reversed and nozzle 62 blows against nozzle 85, the thread being blown out of nozzle 62 and being blown into nozzle 85, which is now used as a catch channel, while passing through eyelet 74 of selvage needle 72.
  • one of the nozzles can also work with a water jet, the other with an air jet.
