Definitions

  • the invention relates to a shedding device for circular weaving of high-weave fabrics according to the preamble of claim 1, as is the general state of the art.
  • the number of shafts of a weave is limited by the number of frames or harness frames.
  • the number of harness frames cannot be increased arbitrarily, since the stroke of each additional harness frame would be extraordinarily large for a given angle of the compartment opening.
  • the invention is therefore based on the object of providing a shedding device for circular weaving of high-weave fabrics.
  • the invention further relates to the use of this shedding device for circular weaving of high-weave fabrics, as specified in claim 3.
  • the advantages that can be achieved by the invention are, in particular, that only as many dish frames are required as if the fabric were woven open, namely the number of layers times the number of warp threads of a layer per weave repeat. Since warp threads of the lower and the upper fabric half are drawn into each dish frame, the same dish frames serve for weaving both the lower and the upper fabric half.
  • the application of the invention is not limited to double-layer or multi-layer sieves, but also relates to single-layer round-woven fabrics.
  • the shedding device has 14 harness frames, which have two strands per binding rappor-t of the chain, namely one strand each for each weave repeat of the upper and lower halves of the sieve 25 and 26 respectively.
  • the harness frames therefore contain twice the number of strands 24 as usual. Instead, however, each strand can also have two strand eyes or two warp threads can be passed through one strand eye.
  • a thread divider 20 is arranged, which in the simplest case consists of a rod that extends over the entire width of the weaving machine.
  • the thread divider 20 is displaceable between an upper and a lower position and is in its upper and lower position at the edge of the opening angle of the compartment. With each change of subject it is moved from one position to the other position, for example by pneumatic, hydraulic, other mechanical or electromagnetic devices which essentially correspond to the devices which serve to raise and lower the dish frames 1 to 14. As can be seen in Fig.
  • the warp threads shown in the drawing by a solid line of the upper sieve half 25 are drawn in such that they run over the thread divider 20 and the warp threads represented by a broken line of the lower sieve half 26 are drawn in such that they run under the thread divider 20.
  • the thread divider 20 In its low position, the thread divider 20 therefore presses down all the warp threads of the lower half of the sieve 26, including those warp threads that run through a raised dish frame. Conversely, in its high position, the thread divider 20 lifts all the warp threads of the upper half of the sieve 25, including those that run through a just lowered dish frame.
  • the 28 warp threads of the selected exemplary embodiment are shown in section as small circles, the warp threads of the upper two lines are numbered 1 to 14 and belong to a weave repeat of the upper half of the sieve 25, while the warp threads of the lower two lines are numbered la to 14a and belong to a weave repeat of the lower half of the sieve 26.
  • the warp threads of a row each belong to a specific position of the fabric. If now a weft thread to be pulled through 28 as shown in FIG. 2, the corresponding G eschirrahmen be raised or lowered, as shown in Fig. 3, wherein the warp wires 1 and la of F ig. 2 run through the harness frame 1 of Fig. 3, the warp wires 2 and 2a of Fig.
  • FIG. 2 run through the harness frame 2 of Fig. 3, etc.
  • a warp thread of the upper 25 and a warp thread of the lower half of the sieve 26 are thus alternately drawn into each harness frame .
  • the weft wire is to pass 28 through the warps 1 to 4, 6, 8, 12 and 14 D A in FIG. 2, these heald frames are shown in FIG. Lowered 3, while the remaining heald frames are raised, as the weft wire 28 under the corresponding warp threads should run.
  • the warp threads 5a, 7a, 9a, etc. of the lower sieve half 26 run through the harness frames 5, 7, 9 etc. raised in FIG. 3, but the weft wire 28 does not run underneath these warp wires, since the thread divider 20 in FIG. 3 is in its deep position so that all the warp wires of the lower half of the sieve 26 are pressed down and the weft wire 28 runs over all the warp wires of the lower half of the sieve 26.
  • FIGS. 4 and 5 show the subsequent passage of the weft wire 28 through the lower half of the sieve or the position of the dish frame and the thread divider 20.
  • the subject is now according to that desired course of the weft wire 28 is formed in the lower half of the sieve 26.
  • the thread divider 20 is in its high position and thus presses all the warp threads of the upper half of the sieve 25 upward, so that the weft wire 28 inevitably runs under all the warp wires of the upper half of the sieve 26.
  • the weft wire 28 is now inserted into the upper half of the sieve 25.
  • the weft wire 28 should run as shown in FIG. 6, for which purpose the position of the dish frame shown in FIG. 7 is necessary.
  • the thread divider 20 is again in its deep position and presses all the warp threads of the lower half of the sieve 26 downwards. The thread divider 20 is thus in its deep position when the weft thread is inserted into the upper fabric half 25 and is in its high position when the weft thread is inserted into the lower fabric half 26.
  • Each harness frame is equipped with twice the number of strands - one half of the strands for the upper fabric half 25, the other half of the strands for the lower fabric half 26.
  • Fig. 8 shows the passage of a weft wire 28 when weaving a three-layer fabric. Only the warp wires 2, 3, 4 and 7 are pulled up over the corresponding harness frames and form the upper side of the shed. The remaining warp wires form the lower side of the compartment opening 22 when the weft wire 28 is pulled through. The position of all the dish frames is shown in FIG. 9.
  • the thread divider 20 presses all of the warp wires that are only required when weaving the lower fabric half 26 downward outside the compartment opening 22. In this way, the warp wires 2a, 3a, 4a and 7a of the above harness frames are displaced from the compartment opening 22.
  • the thread divider 20 is shown with a round cross section. However, it expediently has an oval cross section, the long axis being vertical, in order to give the thread divider 20 stability in the vertical direction and to prevent bending as far as possible.
  • the thread splitter 20 is preferably mounted within a stable support frame, as shown in FIG. 10.
  • the carrier frame surrounds the shed and the thread splitter 20 is held in the carrier frame by steel wires or the like. The carrier frame moves with the thread divider up and down with each change of subject.
  • FIG 11 shows the entire course of the warp threads from the warping roller via the shedding device, the weaving reed 27 (weaving point) to the fabric tree.
  • the path described by the individual warp threads is of different lengths, the path being the longest of those warp threads which run through the low dish harness with the thread divider 20 standing up. Since the thread divider 20 is in the opposite position with each change of subject , it can happen that other warp wires describe the longest path after the next change of subject. The different lengths of the paths described by the individual warp threads can lead to differences in tension in the individual warp threads.
  • the compensator 30 shown in FIGS. 12 to 14 which largely corresponds in construction to the thread divider 20, but is arranged behind the last harness frame, i.e. between this harness frame and the paper roller.
  • the warp wires are drawn in such that the warp wires of the lower half of the screen 26, which run under the thread splitter 20, are also drawn in under the compensator 30.
  • the warp threads of the upper half of the screen 25, which run over the thread splitter 20, are also guided over the compensator 30.
  • the compensator 30 is moved in counter-clockwise fashion to the thread divider 20 in this guiding of the warp threads, i.e. when the thread divider 20 is in its high position, the compensator 30 is in its low position and vice versa.
  • the warp threads can also be guided in such a way that the warp threads that run over the thread splitter 20 are passed under the compensator 30 and vice versa.
  • the compensator 30 is then raised and lowered not in push-pull, but in time with the thread divider 20.
