Definitions

  • the invention relates to a method and a device for shedding jacquard mustard pile warp threads on a double pile loom with at least two superposed weft insertion zones between each adjacent compartment levels, the pile threads on strands - the Pattern and the selected binding accordingly - each one level assigned and finally after the open subject working in this subject level be moved, the group of non-eye pile threads in an upper and / or lower basic commodity and the mustering Pole threads alternately in the upper base fabric and in the lower base fabric involved and spanned between the two basic goods become.
  • U. a. EP 1 069 218 B1 discloses a device for shedding of warp threads on looms with a single weft insertion zone for each warp has a separate shingles drive.
  • the actuators described for this purpose exist from a motor whose drive wheel is connected to a cord (harness) is.
  • the stroke size can vary depending on the distance of the respective strand from the weft stop edge to secure the required bin opening angle be varied.
  • the object of the present invention is the formation of the shed to modify so that, if necessary, using individual actuators
  • For the control of the pile threads reduces the specialist height of the pile threads can be, without this at constant warp density in the shedding cling to each other.
  • this object is achieved by the method according to claim 1.
  • the differences of the specialist dimensions are compensated by the different integration positions on the different basic goods, that the pile threads, when they set as Totpol or as beginning with the patterning Polfaden, perform a smaller stroke in the outer compartment.
  • the advantages of the individually controlled actuators can also be transferred to double pile looms, on which voluminous pile threads are integrated in high density and which has more than one weft insertion plane.
  • Another advantage of the invention is that in this way reduced shed the use of a clear in their size and in its mass reduced batten allows. This leads to an increase the speed of the loom. Also attached to the batten, in the Shed protruding elements - such as guide teeth for the weft insertion member, Auxiliary nozzles with Airjet weft insertion - can be shorter and thus be made lighter and more stable.
  • the claim 3 specifies the claim 1 with respect to the way how one - by the different strokes into the outer compartment - the specialist height of the Can reduce pile threads.
  • the method defined in claim 6 effectively avoids a temporary Jam of pile threads in the area of the middle compartment and thus bows a stapling of the pile threads effectively before.
  • the claim 7 shows a modified method for solving the problem on. Instead of the differentiated positioning of the pile threads in the outer compartments depending on the last bond in one of the basic goods Here a mechanical remedybegrenzer used, which the movement scope those pile warp threads in the area of the batten in their specialist height Limited, from their own basic commodity to the adjacent outer compartment switch.
  • the device described in claim 8 is used in a simple way Realization of claim 1.
  • the modification according to claim 9 supported the loosening of the warp threads from each other.
  • Claim 11 shows an advantageous design and arrangement the shed limit for the execution of the method according to Claim 7.
  • Fig. 1 the principle of the present invention is according to a first Solution variant shown.
  • the double-pile fabric 6 is placed between the panels of the fabric guide 1, starting at the shot stop edge 11 withdrawn and guided.
  • the Pole threads are either in the upper base fabric 61 or in the lower base fabric 62 tied off.
  • the non-patterning pile threads 71 - Also called Totpole - the top fabric 61 are shown in FIG. 4 regularly between back shots 81 and inner shots 82 of the upper 61 involved. The same applies to the non-patterning pile threads 72 or totpole the lowerware 62 too. These are between the back shots 83 and Inner shots 84 of the lower base 62 integrated.
  • the pile thread 73 spans from his last bond in his Basic goods 61 to the top right and touches the neighboring him Weft insertion zone 51.
  • the eyelet 311 of this pile thread 73 leading strand 31 is located on the additional inner upper level O2, the through the two described points (last binding on its basic commodity 61 and the tangent to weft insertion zone 51) is defined.
  • the forming in the range of movement of the reed 21 shed is significantly smaller than the shed that would form when the Eye of the strand 31 - as usual - would move to the position O1. Compare this in Fig. 1, the levels 730 and 740.
  • the upper and the lower compartment limit becomes the center of expertise by the difference amounts a) and b) shifted by up to 10 mm each.
  • the sley 2 or the reed 21 can be shortened or reduced by about this amount.
  • the batten 2 or The reed 21 becomes lighter and more stable.
  • this pile thread 74 is - according to Fig. 3 - from the Middle compartment M2 coming with the eyelet 321 of his strand 32 first to the shortened stroke H1 'moved to the lower level U2.
  • the plane in the the pile thread 74 extends begins at the last binding site in the lower base fabric 62 and touches below and outside the lower weft insertion zone 52nd
  • FIG. 3 The further course of the movement of the eyelet 321 on the strand 32 is shown in FIG. 3 seen.
  • the pile thread 74 is in the following tours each in the outer compartment levels O1 and U1 moved.
  • the shed in the area of Reed 21 is not larger in this case, because the previous Binding site of the pile threads 74, 75, 76 in each opposite Basic product 62, 61 is located.
  • Reducing the shelf height as shown could be special Polmaterialien for clamping the pile threads together and thus lead to the prevention of the compartment opening. This case occurs when a new one for patterning selected pile thread from the same over a long time binding Totpolstrang must be drawn. This usually takes place from the middle compartment from in the each own basic commodity assigned outer compartment.
  • Actuators or motors 37 each associated with a pile warp thread or its strand (compare FIGS. 10 and EP 1 063 326 B1).
  • the motors 37 described therein are received by the central controller corresponding differentiated control program with a shortened Hub, with a staggered start position and with a time-differentiated Middle passage.
  • Fig. 5 is a second variant of the method for limiting the compartment height represented in the range of movement of the sley 2.
  • shed limiters 4 arranged. These shed limiters 4 are located in one the levels that are different from the last bond to the own basic product 61, 62 as an outer tangent to the adjacent weft insertion zones 51, 52 extend upwards or downwards.
  • the shed can also in this embodiment in the range of motion Reed 21 can be kept small.
  • the dimensions of the batten 2 are reduced and allow a high-speed operation of the weaving machine.
  • the shed limiters 4 are formed as tension wires 41, both sides the shed using clamping elements 410, 420 Be anchored frame-fixed (See Fig. 7 and Fig. 8).
  • tension wires 41 are at intervals along the shed with Help of strands 43, which are equipped with eyelets 44 and 45, out. These in turn are fixed to the frame on upper support rails 47 and over Feathers 46 fixed to lower clamping rails 48.
  • the tension wires 41; 42 Be along their axis by means of clamping elements 410; 420 pretensioned, so that the number of trunnions 43 is limited.
  • This arrangement of the shed limiters 4 is sufficiently stable for the intended subject limitation and hinders the insertion of pile threads 71 to 76 in the eyelets 311, 321 of Strands 31, 32 are not.
  • FIG. 9 While in the description of Figures 1 and 5, the staggering of individual end positions and passages of the pile threads in the middle compartment and in the outer compartments has been shown only very schematically, is shown in FIG. 9 on a scaled slightly stretched example of a shed staggering the eyelet positions in the middle compartment M shown.
  • the left triad the strands 31 is associated with the pile warp threads of the upper fabric 61, while the Litzenelle 32 of the lower basic product is associated.
  • the marked eyelet positions 311 M, 321 M in the middle section M1 are on the one hand those positions of the eyelet 311, 321, the pile threads at a Totpolitati in the middle compartment M1 as a temporary end position taking. Pattern these pile threads, then these positions are about those the respective pile threads during the technical assistance to a uniform Take time.
  • Fig. 10 is again schematically the way the drive of the Strands 31 for the pile threads by means of an actuating element - here a Motor 37 - shown.
  • the strand 31 in the lower region leads in its eyelet 311st the pile thread.
  • One of the strand 31 up leading rope 33 is over a loose roller 34 and is fixed to the frame-fixed bar 49.
  • the Axis of the loose roller 34 is replaced by another cable 35 with the cable drum 36 of the actuating element 37 is connected.
  • the cable drum 36 has spiral grooves in which the rope 35 filed filed and released can be.
  • the size of the cable drum 36 kept to a minimum.
  • the required drive torque is increased. That in turn leads to a significant increase in the dimensions of the motors 37. It remains up to the expert, whether he is the double-sided looms required larger compartment dimensions with or without loose roll 34 realized.
  • FIGS. 11 and 12 once again show the movement diagrams, after which the pile threads during the suvertrittes by the Actuators are controlled to be moved.
  • the specialist takes place in essential in the period from leaving the shed by a Weft insertion element S in a first tour and the reentry of Weft insertion element S1 into the shed in a second tour instead
  • the motion diagrams F and F1 show the usual ones Movement form. It begins and ends in the respective prescribed level.
  • the motion diagrams F3 and F4 so changed, at least in the region of the end position of the movement a temporary overtravel H3 is performed before the pile thread remains permanently in its new technical level.
  • An overrun H4 can too be carried out before a specialist.
  • polystyrene used can thus be a pile thread better removed from a threadline become.
  • FIG. 12 shows movement diagrams F5 to F7 of pile threads which at different times the center of expertise in the area E and others Cross pile warp threads. It goes without saying that even in these cases with an overstroke, as described with reference to FIG. 11 has been described.
