Definitions

  • the invention relates to a method for producing a knitted fabric with a cable pattern on a flat knitting machine having the features of the preamble of claim 1.
  • the entire knitted piece is formed in a snap-off technique from a certain width of the braid.
  • a durable knit fabric, knitting threads are processed, which are several times thicker than the knitting threads, which correspond to the machine fineness.
  • a method of manufacturing a braid is known in which only one strand of the braid is subjected to an offset movement in order to cross the strands with one another. Between the offset movements, courses are formed for all strands.
  • the present invention has for its object to provide a new method can be made with the knitted fabric with a cable pattern, the knitting rows in which Um feelingvortician are required to have lower voltages than the knitted fabric produced by the known methods.
  • the object is achieved with a method for producing a knitted fabric with a cable pattern having the features of claim 1.
  • the offset of only one of the strands leads to lower stresses in the knitting rows of the knitted fabric, in which transfer operations are necessary, so that can be dispensed with a Absprengtechnik to produce the knit fabric. Smaller mesh sizes can be achieved and thinner knitting yarns can be used than in the known methods for producing braid patterns, in which both strands of a braid are offset to produce a crossing.
  • the method according to the invention also enables a more favorable, tension-reducing preparation of the crossing of the strands.
  • the preparation consists in forming at least one row of stitches before the lateral offset of the stitches of the one strand, no stitches being formed for the other strand whose stitches are not displaced.
  • the laterally displaceable strand is thereby slightly longer than that which is not displaced, whereby the stresses can be further reduced at the intersection of the strands.
  • Tension at Zopfmustern occur mainly on the two adjacent edge stitches of the strands to be crossed and on the outer edge mesh of that strand, which is not offset on.
  • Another measure for the reduction of thread tensions in the fabric is, prior to the formation of the at least one row of stitches in each case the stitches of the left stitch area which adjoins the strand to be displaced, against the direction in which the strand to be offset is added later to intersect the strands to move laterally. Over one or more rows of stitches, space is thus created in a gentle manner for the stitches of that strand which is not displaced.
  • the links mesh area can preferably be offset by as many needles as the strand has stitches.
  • At least one tuck loop can be formed between the staggered left stitch area and the strand to be offset.
  • the provision of tuck loops is also a well-suited way to reduce thread tension in the needle bed offset.
  • the number of courses to prepare the crossing of the strands depends on the strand width, the yarn quality used and the machine fineness. Preferably, two courses can be formed before crossing the strands.
  • the stitch formation after the first two offset steps reduces the tensions which arise between the outermost loop of the strand which is not staggered and the innermost loop of the adjacent left stitch area and the adjacent stitches of the two strands.
  • the Fig. 1.1 to 1.4 illustrate the knitting sequence for crossing the strands of a two strand braid with each of the strands having six stitches each.
  • This number of stitches is merely exemplary.
  • the strands of the braid can consist of any number of stitches.
  • the more meshes the strands of the braid contain, the greater the advantage of using the braid The method of the invention over the method of the prior art, since the method of the invention must not be avoided even with wide braids on enlarged stitches and the use of thick knitting threads.
  • a knitting machine which is equipped with a transfer device and a needle bed offset device.
  • row R1 the last row of knitting is shown before the beginning of the crossing of the plaits.
  • the width BZ of the braid in the illustrated example comprises twelve needles of the front needle bed, which form right-hand stitches.
  • the first strand ST1 is formed with the needles 12 to 17 and the second strand ST2 with the needles 18 to 23.
  • Each of the two strands thus comprises six needles.
  • the braid is flanked by left-knit areas LR1 (needles 6 to 11) and LR2 (needles 24 to 29).
  • the link mesh areas LR1 and LR2 must each have as many stitches as one of the strands of the pigtail.
  • the repeat region of the braid extends in the example shown via the needles 6 to 29.
  • the further knitting sequence is shown exclusively for this repeat region. It will be appreciated that a plurality of such plait repeat regions can be arranged next to one another over the width of the knitted piece. Or it may be provided in addition to the cable pattern other pattern areas.
  • the offset of the rear needle bed from its basic position by three needles to the left.
  • stitches are formed for the first strand ST1 of the braid.
  • the needles 6 to 11 of the back needle bed form stitches for the left-knit area LR1 and the needles 24 to 29 for the left-knit area LR2.
  • the needle 14 of the rear needle bed is that needle of this needle bed which follows the extreme left needle of the braid. It forms a catching handle. This reduces the thread tension acting on the edge needle 12 of the braid when further offset movement of the rear needle bed occurs to the left.
  • Row R3 shows such an offset movement of the rear needle bed three more needles to the left.
  • needles 12 to 17 of the front needle bed forming the first strand ST1 of the braid are formed into the needles 6 to 11 and 24 to 29 of the back needle bed forming the two left mesh areas and stitches 14 are formed with the needle.
  • the stitches of the first strand ST1 of the braid are transferred from their needles of the rear needle bed to the opposite empty needles of the front needle bed.
  • the loop of the needle 14 of the rear needle bed is transferred to the needle 20 of the front needle bed, which already carries a loop of the strand ST2.
  • stitches for the pigtail portions are formed with the needles 6 to 11 and 24 to 29 of the back needle bed, and stitches for the pigtail are formed with the needles 18 to 29 of the front needle bed.
  • the same process is repeated in row R7.
  • the knitting course R7 is not necessarily required by the knitting process, but also takes tension out of the fabric and thereby simplifies the subsequent transfer operation in row R8 in which all the loops of the braid are transferred from their needles of the front needle bed to opposite empty needles of the back needle bed. so that in series R9 a displacement of the rear needle bed can be done back to its basic position. Subsequently, all stitches of the braid are transferred from the needles of the rear needle bed to their opposite empty needles of the front needle bed. Thus, the stitches of the braid are back on their original needles.
  • stitches for the plait stitches are formed with the needles 6 to 11 and 24 to 29 of the back needle bed stitches for the left stitching areas and with the needles 12 to 23 of the front needle bed stitches.
  • the knitting R10 is repeated until the next crossing of the strands of the braid must be done.
  • Fig. 2 illustrates the production of a braid with three strands, which in the example shown again each have six stitches.
  • the crossing of the strands is done in the example shown in that each of the outer strands are passed behind the middle strand by lateral displacement movements of the needle bed. Of course, they could also be passed before the middle strand.
  • the width BZ of the braid in the illustrated example comprises eighteen needles of the front needle bed which form right-hand stitches.
  • the first strand ST1 of the braid is formed with the needles 9 to 14, the second strand ST2 with the needles 15 to 20 and the third strand ST3 with the needles 21 to 26.
  • the braid is bounded by left-knit areas LR1 and LR2, each also comprising six stitches.
  • the mesh size of the link mesh areas LR1, LR2 must be at least the same as the mesh count of a strand.
  • a first row of stitches is formed in order to prepare the crossing of the strands by reducing stresses in the fabric, but no stitches are formed for the middle strand ST2.
  • the needles 3 to 8 for the left-hand side mesh area LR1 and the needles 27 to 32 for the right-hand side mesh area LR2 and on the front needle bed the needles 9 to 14 and 21 to 26 for the two outer strands ST1 and ST3 knit ,
  • the stitches of the right-hand side knit area LR2 are transferred to opposite empty needles of the front needle bed so that these stitches do not take part in the subsequent offset movement of the back needle bed three rows to the left shown in row R4. After the offset, the stitches of the left stitch area LR2 are reloaded onto the back needle bed.
  • a second row of stitches is then formed, again forming no stitches for the middle strand ST2.
  • the needles 9 to 14 and the needles 21 to 26 for the outer strands ST1 and ST3 are knitted on the front needle bed.
  • the needles 3 to 8 of the back needle bed form stitches for the left-knit area LR1 and the needles 30 to 35 for the left-knit area LR2.
  • a tuck is formed on needle 11 of the rear needle bed following the extreme left needle of the braid. This tuck lessens the thread tension acting on the edge needle 9 of the braid when the rear needle bed is again offset to the left.
  • the stitches of the left-knit area LR2 which are not to participate in the offset process, are relocated to the front needle bed, as row R6 shows. Only then does the offset of the rear needle bed by three more needles to the left take place in row R7. Subsequently, the stitches of the left stitch area LR2 are hung back onto the back needle bed. Thereafter, a stitch course again formed, again for the middle strand ST2 no stitches are formed. The occupied with the tuck looper needle 11 of the rear needle bed also forms a mesh.
  • the stitches of the first strand ST1 and the third strand ST3 are transferred from their needles of the front needle bed to the opposite empty needles of the back needle bed. Subsequently, the rear needle bed in row R10 is returned to its basic position. The loops of the third strand ST3 of the braid are hung back on opposite empty needles of the front needle bed. Between the needles of the second strand ST2 and the needles of the third strand ST3 are now six free needles. Since the stitches of the left-hand knit edge LR2 are not intended to undergo any further offsetting movements, they are transferred to the opposite needles 33 to 38 of the front needle bed before the back needle bed is shifted from the basic position by six needles to the right in row R11.
  • the loops of the first strand ST1 of the braid are transferred to their opposite empty needles 21 to 26 of the front needle bed.
  • the stitches of the first strand ST1 are now to the right of the original middle strand ST2 of the middle pigtail, d. H. the intersection of strands ST1 and ST2 is complete.
  • the loop of the needle 11 of the rear needle bed is transferred to the needle 17 of the front needle bed, which already carries a loop of the rope ST2.
  • the stitches of the left stitch area LR2 are hung back onto the back needle bed.
  • row R16 stitches are again formed for all areas of the braid and the two left-hand stitch areas, before another row of stitches follows in row R17, in which no stitches are formed for the middle strand ST2. From row R17, the crossing of strands ST2 and ST3 is thus prepared.
  • the stitches of the left stitch area LR1 that are not to be moved are transferred to the front needle bed.
  • the stitches of the third strand ST3 of the braid are transferred to the opposite empty needles of the front needle bed.
  • the meshes of the third strand ST3 are now located between the meshes of the strands ST1 and ST2, d. H. the intersection of strands ST3 and ST2 has taken place.
  • the loop of needle 24 is transferred to needle 18 of the front needle bed, which already carries one loop of rope ST2, and the stitches of the left mesh section LR1 are hung back onto the back needle bed.
  • the Zopfnchung begins with the left strand ST1. If the Zopfnchung done with the right strand ST3, the knitting processes are carried out from the series R17 before the knitting sequences from the series R2.
