Definitions

  • the invention relates to a pneumatic weaving machine.
  • the reed is composed of lamellae with recesses, which together delimit a tunnel that is open sideways to the stop line for guiding the air flow that supplies the weft feed.
  • the edges of the slats of the auxiliary comb facing the reed together form a slightly curved end wall, by means of which the lateral opening of the guide tunnel delimited by the reed is closed during the shooting phase.
  • the invention now aims to further improve this known weaving machine and in particular to further improve the design of the guide tunnel for pneumatic weft conveying.
  • this goal is achieved in that the lamellae of the reed moving back and forth in the warp direction together with an auxiliary comb arranged on the stop side and consisting of lamellae profiled in their plane, create a tunnel for pneu limit the conveyance of the weft threads and in which the auxiliary comb can be moved with respect to the reed between a closed position taken during the weft phase, in which the conveyor tunnel is closed all around, and an open position, taken during the reed stop phase, in which the weft threads emerge from the side of the tunnel can, the reed being composed of straight reed rods.
  • pneumatic weaving machines in which a right reed is used together with an auxiliary comb are generally known. In these known cases, however, it is a comb in which the reed does not contribute to the formation of a weft tunnel in that the auxiliary comb is composed of annular lamellae with an exit gap for the weft threads.
  • 1 shows the shed delimited by the upper and lower warp threads 2.
  • the reed 3 composed of straight reed rods works with an auxiliary comb 4 composed of profiled lamellae.
  • the straight reed bars together with the slats of the auxiliary comb 4 form a completely closed guide tunnel 5 for the air flow by means of which the weft threads are inserted into the shed.
  • This air flow is supplied in a known manner by a blowing nozzle (not shown in the drawing), as is the reed on the blowing nozzle (see FIG. 2) which can be moved back and forth about the axis 6.
  • the shooting process which is already has already been started during the preceding movement of the reed 3 from the stop position to the retracted position shown, it will end shortly after the reed has started to move again in the direction of the stop line 8 according to the arrow I.
  • the reed stop phase takes place.
  • the weft thread entered in the shed must be cleared from tunnel 5.
  • the auxiliary comb 4 can be moved in relation to the reed 3 according to the arrow II, so that a space is created between the reed and the auxiliary comb 4, via which the inserted weft thread can emerge from the tunnel.
  • the auxiliary comb 4 with its lamellae passes between the warp threads out of the shed so that the inserted weft thread can hit the cloth unhindered.
  • the auxiliary comb with its lamellae is brought back into the shed between the lower warp threads in such a way that as soon as possible together with the reed a tunnel closed around it to promote the next weft.
  • the mechanism used for this will now be explained in more detail with reference to FIG. 2.
  • This mechanism is shown with solid lines, which of the The stop position of the reed corresponds.
  • the auxiliary comb 4 is attached to the free end of a support arm 9, which is mounted with its other end pivotable about an axis 10 on a fixed but adjustable part 11 of the machine frame.
  • a hinge point 13 is formed on the drawer by means of a socket 12, which is connected to an intermediate hinge point 14 of the support arm 9 by means of a connecting rod 15.
  • the articulation points 10, 13 and 14 are arranged in relation to the axis of rotation 6 of the drawer 7 in such a way that in the first phase of the backward movement of the drawer with the reed from the stop position, the auxiliary comb 4 moves rapidly relative to the reed 3 in the direction of a closed weft conveying tunnel , while in the next phase of the receding movement of the reed until the retracted position is reached, there is only a slight movement of the auxiliary comb with respect to the reed. All of this emerges from the comparison of the most left-hand, retracted position and the intermediate layer in FIG. 2. As can be seen, the conveyor tunnel 5 is already practically closed in the intermediate layer shown, so that the shooting phase can begin with this intermediate layer of the reed .
  • auxiliary bale nozzles distributed over the weaving width.
  • auxiliary blowing nozzles which are not shown in the drawing, could be parts of the auxiliary comb 4, in a manner known per se and described, for example, in the above-mentioned European patent application.
