Definitions

  • the invention relates to a method for producing a leno base fabric according to the Features of the preamble of claim 1 and a weaving machine Method implementation according to the features of the preamble of claim 4.
  • a weaving machine with a first heddle frame and a second heddle frame, of which each heddle frame is accommodated in a vertically displaceable manner in the shaft guides of the weaving machine.
  • a heddle-supporting subframe is accommodated, which is accommodated so that it can be moved back and forth within the first heddle frame, for example, in the direction of the weft thread insertion.
  • the subframe is slidably received within the heddle frame in supports of the heddle frame together with an axis running in the weft direction.
  • the strands of the subframe alternately consist of short and long strands, each short strand having a strip-like shape, the free end of which has a twisted head part with a strand eye for passing a leno thread.
  • the known solution requires a relatively high one Construction work to next to the execution of the usual oscillating vertical Sequence of movements of the at least two heddle frames is a transverse one oscillating back and forth movement of a so-called underframe enable.
  • EP 0 369 525 B1 discloses a method for producing a lathe or Cross weave with at least one heald frame for the upright threads and two heald frames for the leno threads. In this version, too, the relatively high construction costs are not too great misjudge.
  • a leno selvedge device for producing firm edge edges on fabrics, which consists of two lifting healds, which lifting healds are arranged on two reciprocally moving heald frames of a weaving machine.
  • the device for forming a leno edge also comprises a half heald which is alternately carried along by the lifting healds in accordance with the movement of the heald frames.
  • the half-strand has two legs which converge at their upper end to form a head with an eyelet for guiding the standing thread.
  • the object of the invention is a method for producing a leno base fabric and to specify a weaving machine for its implementation, after which while maintaining the the tissue manufacturing process known by means of at least a first and of a second strand frame, a lathe base fabric can be produced.
  • the object is achieved according to the method in that lifting strands with half-strands known per se according to DE 197 50 804 C1 are used as shedding agents in combination with at least two strands known per se. So instead of the usual healds, one of the at least two heald frames is equipped with a plurality of first lifting healds for half healds and the other heald frame is equipped with the same plurality of second lifting healds for the half healds.
  • the device known per se for forming a leno selvedge in its multiple arrangement over the desired weaving width of a weaving machine is an excellent means of producing a leno weave.
  • the use according to the invention of the known lifting strands with half-strand as shedding means enables an increase in performance in the production of leno base fabrics by more than double compared to the prior art. If, according to the prior art, a leno base fabric of about 2400 mm width could be reached at a machine speed of about 200 rpm, the solution according to the invention achieved a machine speed of more than 450 rpm on air jet looms.
  • the nominal thread tension of the vertical thread chain is greater than the nominal thread tension of the Leno thread chain, namely the nominal chain tension of the leno thread chain corresponds approximately to that Half of the nominal chain tension of the vertical thread chain.
  • a loom known per se is used to carry out the method, e.g. a Weaving machine with fluidic (air, water) or mechanical weft insertion means, whose shedding means consist of stranded frames known per se, which according to the invention can be combined with a large number of lifting strands known per se with half strands.
  • the shedding means can consist of a jacquard device known per se in combination with a large number of lifting healds with half heddle known per se.
  • the invention provides that the wiping roller over its Working width has a first cam, which is effective on the leno thread chains and that the coating roller over its working width, diametrically opposite the first cam, has a second cam, which causes the length compensation in the vertical thread chain.
  • the length compensation for maintaining the desired constant warp tension both in the leno thread chain and in the standing thread chain takes place in such a way that the coating roller is operatively connected to an eccentric drive, with a length compensation alternately in the sense of maintenance in the stand thread and in the leno thread chain there is an almost constant tension in the two chains.
  • At least one warp tension sensor for detecting the respective actual warp tension is arranged in the run of the respective chain between the coating roller and a first deflecting means of the chain in question.
  • the one tension sensor is connected to the program control of the weaving machine in a signal-transmitting manner.
  • a setpoint / actual value comparison of the warp tension of the leno thread chain and the standing thread chain takes place in the program control.
  • the warp let-off drive of the relevant warp beam is controlled accordingly and the warp tension is readjusted.
  • This procedure is known and so far is not the subject of the solution according to the invention.
  • at least one tension sensor can be arranged in the area of the finished fabric between the binding point of the fabric and a first means for deflecting the fabric, which indirectly detects the warp tension of both chains. This at least one tension sensor is also connected to the weaving machine control in a signal-transmitting manner.
  • the schematically illustrated weaving machine 1 comprises at least a first heddle frame 14 and a second heddle frame 15, wherein in each case one heddle frame 14 and the other heddle frame 15 are moved alternately vertically up and down by drive means, not shown, for the purpose of forming a shed 2.4.
  • a plurality of first lifting strands 14.1 of a leno selvedge device known from DE patent 197 50 804 is accommodated in the heddle frame 14.
  • the same plurality of second lifting strands 15.1 is accommodated in the heddle frame 15.
  • Each first and second lifting heald 14.1, 15.1 works alternately with a half heald 21.
  • the shed forming means do not consist of heald frames with a plurality of healds, but instead of at least two heald frames, with a first plurality in the first heald frame 14 and in the second heddle frame 15 a second plurality of lifting heddles 14.1, 15.1 with half heddles 21 are received.
  • the weaving machine 1 provides according to the invention that the coating roller 6 has a first cam 6.1 and a second cam 6.2 arranged diametrically opposite the first cam 6.1.
  • the leno thread chain 2.1 is guided over the cams 6.1 and the vertical thread chain 2.2 is guided over the cams 6.2.
  • a suitable means according to the invention is the coating roller equipped with the cams 6.1, 6.2, which in turn is operatively connected according to the invention via coupling members 22 to an eccentric drive 18 connected to the main drive shaft 17 of the weaving machine 1.
  • the eccentric is set in such a way that the cams 6.1, 6.2 alternately in one of the chains compensate for the chain elongation resulting from the reduction of the tensile stress in the chains.
