Definitions

  • the invention relates to a loom, in particular an air jet loom a leaf bar carrying a reed, which is used for the purpose of entry and posting of weft threads on the stop edge of a fabric from an entry position into a Stop position and in the opposite direction about a longitudinal axis of a drive or blade shaft executes uniform oscillating movements with a first nozzle arrangement, which consists of several main nozzles with blowpipe, the main nozzles after one Order system are included in a main nozzle block and where the Main nozzle block is connected to the blade strip which carries out the oscillating movements, and with a second, upstream of the first nozzle arrangement, stationary nozzle arrangement, which consists of several pre-nozzles with blowpipe, the Thread guide channel of each blowpipe of the respective pre-nozzle at the time of Weft thread entry aligned with the thread guide channel of the blowpipe of the respective Main nozzle is opposite.
  • Known air jet looms have one for weft insertion Main nozzle block with several in it according to a certain order system recorded, pneumatically actuated main nozzles with a blow pipe of a certain length, wherein the respective blow pipe is directed to the weft insertion channel of a reed.
  • the main nozzle block is on the weaving machine's leaf bar carrying the reed arranged and in such a way that the main nozzle block is adjustable relative to the reed.
  • the respective pre-nozzle has a blow pipe of a certain length, which in the direction of respective main nozzle is aligned that the weft damaging Weft deflections are largely avoided.
  • the object is achieved in that the individual pre-nozzles with a blowpipe according to a classification system of the main nozzles in the main nozzle block Order system are included in a pre-nozzle block, which order system enables that by aligning a single pre-nozzle to the main nozzle in question all other pre-nozzles are aligned with the relevant main nozzles during the weft insertion even if the pre-nozzle block is on one of the blade strips independent, stationary carrier is mounted.
  • the pre-nozzle block can be arranged on a carrier connected to the weaving machine so that it can be rotated about its longitudinal center axis in a corresponding arrangement system.
  • a specific order of the pre and main nozzles is given, for example, if the center axes of the nozzles are arranged symmetrically about the longitudinal center axis of the nozzle blocks on a circular path. In such a case it is achieved that by rotating the pre-nozzle block about its longitudinal center axis, each pre-nozzle can be assigned to any main nozzle.
  • Such a procedure can be of importance if weft threads of different quality are processed into a fabric and, for example, a weft thread requires a pre-nozzle which is designed differently from the main nozzle.
  • the relevant front nozzle can then be assigned to the relevant main nozzle within a short period of time. It is therefore essential to the invention that with the alignment of a single pre-nozzle on the main nozzle in question, all other pre-nozzles are inevitably aligned with their associated main nozzles.
  • the weaving reed 1 which is only partially shown, is mounted on the so-called leaf bar 2, a weaving machine 11, which is not shown here.
  • a main nozzle arrangement 5 is shown detachably connected to the blade strip 2 in front of the reed 1.
  • the blade bar 2 periodically swings together with the reed 1 for the purpose of attaching weft threads 3 to the stop edge of a fabric (not shown here) about the longitudinal axis 4a of a drive or blade shaft 4.
  • the main nozzle arrangement 5 consequently also swings about the axis 4a in the movement rhythm of the blade strip 2.
  • the main nozzle arrangement 5 forms a main nozzle block 6.
  • the main nozzles 5a are arranged in the main nozzle block 6 according to a certain system. Such a particular system is shown in Figures 4, 6 and 8.
  • the main nozzles 5a are equipped with a blow pipe 5b.
  • a thread guide channel 5b runs through the main nozzles 5a and the associated blow pipe 5b over their length.
  • the main nozzle block 6 and the free ends of the blowpipes 5b are carried by a cooler 13, which establishes the connection to the sheet bar 2.
  • the connecting means 14 are shown symbolically.
  • a pre-nozzle arrangement 8 is positioned in front of the main nozzle arrangement 5 in the weft direction 7.
  • the pre-nozzle arrangement 8 is stationary connected to a machine-fixed support 12.
  • a holder 15 accommodates a pre-nozzle block 9, in which pre-nozzles 8a with a blowpipe 8b are integrated according to the invention, namely according to an order system which corresponds to that of the main nozzles 5a in the main nozzle block 6.
  • the cooler 15 is connected to the carrier 12 via symbolically represented connection means 16.
  • the arrangement system of the pre-nozzles 8a in the pre-nozzle block 9 is shown in FIGS. 3, 5 and 7.
  • the sheet bar 2 with the superstructures 1, 5 and 13 is in the insertion position of the weft thread 3.
  • the pre-nozzle arrangement 8 is permanently in this position, as a result of which the thread guide channels 5b 'and 8b' then lie flush with one another.
  • Such an arrangement has the advantage, inter alia, that deflections of the weft threads at the outlet of the blowpipes 8b and at the inlet of the main nozzles 5a are excluded at the time of the weft thread insertion and that, as already mentioned above, due to an identical ordering system between the main and pre-nozzles and the combination of all pre-nozzles in one pre-nozzle block, the effort for aligning the pre-nozzles on the main nozzles is minimized.
