Definitions

  • the invention relates to a weaving machine for producing leno fabrics and a needle bar for such a weaving machine.
  • the element for the leno threads can be, for example Laying rail or leno heald frame (see DE-A-23 53 658) his.
  • the element for the upright threads can, for example, be a needle bar or be an upright thread element that also functions as a Webblatts (see. DE-A-466 340).
  • a leno tableware which a number of Includes standing needles; between two adjacent standing needles a stop slat for a safe change of the leno threads arranged.
  • the standing needles and stop slats are on their lower one End clamped in a beam; at the top are the Standing needles free, the stop slats loosely guided.
  • the object of the invention is to produce a weaving machine To create leno fabrics with a handicap between the standing round Leno threads are defused. This object is achieved by the in claim 1 defined weaving machine solved. In addition, funds should be created to eliminate the mentioned consequence of thread obstruction. This additional task is solved by the weaving machine according to claim 5.
  • the weaving machine for producing leno fabrics has one element Standing needles, in particular a needle bar. Form the standing needles a row in the direction of the longitudinal extension of the element. The Side surfaces of the standing needles close with a normal to the above Longitudinal extension an acute angle that is greater than 1 °.
  • claims 2 to 6 relate to advantageous embodiments the weaving machine according to the invention.
  • Subject matter of claims 7 to 10 is a needle bar to a weaving machine according to one of claims 1 until 6.
  • a leno fabric 1 is made Weft threads 12 and warp threads, namely upright threads 13 and leno threads 14.
  • the upright threads 13 with a needle bar 3 and the leno threads 14 are guided with an insert element 4.
  • the needle bar 3 carries needles 31 with eyelets 32, which are relatively stiff eyelet rods.
  • the Insert element 4 contains an insert rail 41 which has a perforated rail Holes 42 is.
  • a sequence of regularly arranged holes 42 is dash-dotted lines indicated as strips 42 '.
  • the Transport direction 10 of the warp threads 13 and 14 (arrows 10a and 10b) and the Fabric 1 (arrow 10c) from the back to the front.
  • the transport direction 10 runs from right to left.
  • a reed is used to strike a freshly inserted weft thread 12 ' 2 operated between the needle bar 3 and the tissue 1: double arrow 20.
  • Die Needle bar 3 and the insert element 4 are up and down in opposite directions moved: double arrows 30 or 40a.
  • the first movement component 40a the insertion rail 41 is a second movement component Offset movement 40b overlaid.
  • the stroke of the offset movement 40b is so chosen that the leno thread 14 each from a first gap, the between adjacent standing needles 31 and 31 'to a second Gap that is adjacent to the first is moved. After a shot entry this change of position of the leno thread 14 is again in reverse Direction.
  • the stroke is at least equal to the distance between the adjacent needles 31 and 31 '.
  • stop lamellae 34 are arranged between the standing needles (see FIG. 3), which protrude above the standing needles 31 and so the immersion of the Force leno thread 14 into the correct gap 34. So the first Movement component 40a of the insert element 4 outside the area of the upright threads 13 can be done via a deflecting rod 53 deflected downwards.
  • Insert element 4 and the needle bar 3 move so that the for Upright and leno threads 13 and 14 necessary movement sequence for Formation of a shed for the weft insertion results.
  • the needle bar 3 is on a first toggle lever 54a, 54b between a first axis of the Swivel arrangement (not shown) and a fixed joint 54 arranged. By an up and down movement 30 'of the lever arm 54b results the movement 30 of the needle bar 3.
  • a second axis 71 that is parallel is arranged to the first axis, a second toggle lever 71a, 71b and an up and down movement 70 'which is reciprocal to the movement 30' in an opposite pendulum rotation 70 with respect to the first axis is offset.
  • a Connection 74 between the second axis 71 and the insert element 4 transfers the swivel movement to it and thus generates the vertical one Movement component 40a of the insertion rail 41.
  • the horizontal Movement component 40b is not shown with another Mechanism manufactured.
  • the needle bar 3 shown in detail in FIG. 3 comprises a large number of standing needles 31 which a row in the direction of the longitudinal extension A of Form bar 31.
  • the inclination of the needles 31 is in relation to the upright threads 13 manufactured in such a way that the double deflection of the upright threads 13 reduced when passing through the eyelets 32.
  • the standing needles 31 and stop lamella 34 are in one known manner attached to the base in a base 5.
  • the Stop slats 34 are elastic and resiliently thin, so that a lateral deflection in the direction of the Can exercise barrel extension A.
  • the inclined standing needles 31 and stop plates 34 are included Advantage aligned parallel to each other.
  • the Cross sections each have the shape of a segment of a circle.
  • the lower part the base 5 is a profile rod 50 with a longitudinal groove into which the or individual standing needles 31 are inserted for anchoring.
  • the upper ends of the stop slats 34 are through a wire 35 or another linear element, for example a fine chain, connected. This is a measure to take one over the stop slat prevent the leno threads from soaring upwards.
  • the wire or the element is each in an opening 35 of the Stop slat 34 inserted loosely, so that the stop slats 34 laterally remain deflectable.
  • FIG. 4 shows a cross section through the standing needles 31, 31 'and Stop slats 34 of a known needle bar 3, the section through the eyelets 32 is placed.
  • the needles 31 are perpendicular to Barrel extension A.
  • the alley width, d. H. the distance a between Standing needle 31 and stop lamella 34 is drawn so that a Change of position of the leno thread 14 - indicated by the arrow 40c - seems to be able to be carried out unimpeded by the upright thread 13.
  • the space is narrower and / or it is done Transverse vibrations of the threads, so that there is usually a mutual disability between the threads 13 and 14 results.
  • the solution according to the invention is shown by which the disability can be defused or eliminated: the standing needles 31 and - in Example shown - the stop slats 34 are at an acute angle ⁇ inclined relative to the barrel extension A (see Fig. 4).
  • the leno thread 14 is inclined by the outer edge 310 (or 310 'for the dot-dash position of the leno thread 14) of the Upright thread 13 pushed away.
  • the tendency has the consequence that the alley width is smaller than that original distance is a. Thanks to the resilience of the stop plate 34 this can be deflected laterally by the leno thread 14 (arrows 340), so that the alley width becomes sufficiently large.
  • Figures 6 to 7 show two side views and a top view of one second embodiment of the needle bar 3.
  • the two Base rods 51 a and 51 b are designed such that the standing needles 31 and stop lamellae 34 can be inserted into grooves 510. The distances are no longer determined by a wire 52 (Fig. 3), but by the location of the grooves 510.
  • the arrangement of the standing needles 31 and stop lamellae 34 are terminated at each end by a stop rod 37. These are each arranged adjacent to a standing needle 31 and form a largely rigid stop for the terminal leno threads 34 terminal streets are therefore somewhat wider than the inner streets Lanes trained.
