Definitions

  • the present invention relates to an air weaving machine with a device for forming a fabric alley or the like according to the preamble of claim 1.
  • Such fabric alleys are required, for example, to produce an insert edge from this fabric alley by cutting the weft thread in this area.
  • the fabric lane is formed by saving the warp threads at the location of the desired fabric lane in the fabric, so that only weft threads are present at this point when the weft is inserted.
  • the disadvantage of the known device is that) a reed extending over the entire width of the weave is relatively expensive. If a reed is damaged at a certain point, it must be replaced as a whole.
  • Another disadvantage of the known device is that the mechanics of the insertion device must be arranged so that it can be moved and driven over the fabric web in order to accommodate the mechanics when the sheet is stopped to bring outside the area of the reed.
  • the invention is therefore based on the object of developing an air-jet weaving machine of the type mentioned at the outset in such a way that a simpler insert can be provided at lower production costs.
  • the technical teaching according to claim 1 serves to solve the problem.
  • An essential feature of the invention is that there is no longer a reed that extends over the entire width of the fabric, but that this reed is divided into any number of sub-reeds, which are mounted together on a sheet bar, with the sub-reeds each at the location of the reed there is a gap in the desired fabric alley.
  • a reed filler piece is arranged in the reed gap, which simulates the ventilation properties of the air inlet duct in this area.
  • the weft thread can also be inserted undisturbed through the entry channel over the entire width of the weave.
  • the reed filler is fixed to the weaving machine in such a way that it comes into alignment with the reed pieces (partial reed) in the rear leaf position in which the weft is inserted. Only in this position must the reed filler simulate the weft insertion channel in the area of the reed gap in order to ensure undisturbed insertion of the weft thread over the entire width of the weave. In all other reed positions, such a simulation is not necessary, and it is therefore sufficient if the reed filler piece remains in the stated position when the blade stops and only fills the reed gap there.
  • the reed filler In the forward position of the reed, the reed filler remains in its rear position and the insert with its insertion mechanism reaches through the reed gap.
  • This has the essential advantage that the entire insertion mechanism of the insert does not have to be brought outside the area of the pivotable reed, because - as shown above - the insertion mechanism can reach through the gap of the reed.
  • tissue processing units can also be provided instead of the insert.
  • the arrangement of an insert which essentially consists of a clamp, scissors and corresponding insert needles, is preferred.
  • other edge mechanisms can be used instead of the insert with needles, e.g. B. welding or gluing devices, which could then also have a clamp and scissors, but do not insert the cut weft, but z. B. weld or glue.
  • the struck weft thread is thus reliably gripped and clamped and can subsequently be cut and inserted by known insertion needles to form an insert edge.
  • the reed filler only in the area of the specialist disclosure, i.e. must simulate the ventilation characteristics of the reed when entering the weft.
  • the reed filler is designed in the same design as the other part reed.
  • the reed filler is designed as a simple plate, in which an entry channel is incorporated.
  • a relay nozzle is connected to the reed filler is to ensure a corresponding carrying and guiding function for the weft thread to be entered in the area of the reed filler.
  • the type and design of the reed filler also depends on the width of the desired fabric lane.
  • the reed filler If a relatively wide lane of fabric is desired, then it is necessary to make the reed filler as identical as possible to the rest of the reed in order to avoid disturbing the weft thread. If only a narrow fabric lane is required, then the ventilation properties of the reed filler are not so important and it is therefore sufficient, for example, in this case to design the reed filler as a solid plate with an air inlet channel incorporated into it.
  • Another advantage of the technical teaching according to the invention is that the manufacturing costs for a reed according to the present invention are significantly lower. It is no longer necessary to produce a reed that spans the entire width of the weave, but it is sufficient to attach appropriate reeds. If one part of the reed is damaged, it is sufficient to replace this individual part of the reed, the other part reeds remain unaffected.
  • the reed of the air-jet weaving machine consists of two partial reeds 1, 2, which are arranged in alignment with one another on a common sheet bar 11.
  • the two partial reeds 1, 2 form a reed gap 8 which, in the rear position of the sheet bar 11, is formed in alignment by a reed filler 9 when the weft is inserted.
  • the reed filler 9 is designed in the same way as the partial reed 1, 2, ie the number and spacing of the individual reed rods in the reed filler 9 approximately equal to the number and spacing of the reed rods in the partial reeds 1,2.
  • Figure 1 it is shown that the compartment 5 is open and that in this position a weft thread is inserted into the entry channel 10 of the partial reeds 1, 2, the entry channel 10 of the reed filler 9 (see FIG. 3) with the rest of the entry channel 10 of the partial row 1,2 is aligned.
  • the open compartment according to FIG. 2 is formed by the warp threads 6, the fabric 7 being formed beyond the leaf stop.
  • the reed filler 9 is fastened to a machine-fixed holder 13, to which the insert 12 can also be fastened. Below the holder 13, the fabric alley extending in the fabric 7 in the longitudinal direction of the warp threads 6 is formed.
  • FIG. 2 shows that the sheet 11 previously pivoted backward in the direction of the arrow 3 is pivoted forward in the direction of the arrow 4 up to the sheet stop and that the aforementioned gap 8 then forms.
  • the reed filler 9 remains in the front leaf position (at the leaf stop) of the partial reed 1,2 in its rear position, so that the insert 12 engages with its insertion mechanism in the reed gap 8 that is now forming, which - as described above - is stationary is arranged.
  • the individual actuating parts of the individual insertion mechanism can be pivoted and, if necessary, displaced in a manner known per se. In any case, the entire mechanism no longer has to be displaceable in the direction of the longitudinal axis of the warp threads, as in the prior art be trained.
  • each insertion needle 15 being assigned a rotatable and, if appropriate, displaceable shaft 16.
