Definitions

  • the invention relates to a method for producing a patterned warp knitted fabric according to the preamble of claim 1 and to a warp knitting machine for executing the method according to the preamble of claim 6.
  • US Pat. No. 3,999,407 describes a method for producing a patterned warp-knitted fabric of the type mentioned at the beginning.
  • the pattern threads are each introduced into only one slip stitch.
  • This has the disadvantage that such a pattern is very narrowly limited to the slip stitch and that a relatively large amount of non-patterned basic knitted fabric of the warp knitted fabric appears between adjacent patterned slip stitches, which adversely affects the pattern.
  • such a warp knitted fabric has the disadvantage that the warp knitted fabric tends to unravel when a stitch is destroyed.
  • this patterned fabric has the disadvantage that the pattern from row of stitches to row of stitches must always be the same for all stitches, i.e. all slip stitches that have a pattern thread can only be patterned together or not in a row of stitches. As a result, the pattern of the warp knitted fabric has narrow limits.
  • the object of the invention is to provide a method and a warp knitting machine with which patterned warp knitted fabrics can be produced, in which the pattern threads enable better coverage of the basic knitted fabric, in particular between patterned slip stitch stitches, and which moreover has a lower tendency to rub when a stitch is destroyed.
  • the stated object is achieved by the method having the characterizing features of claim 1 and the warp knitting machine, such as a crochet galloon machine, having the characterizing features of claim 6.
  • the pattern thread in the case of the pattern is placed over at least two, possibly also three or more knitting needles creates a connection between two, possibly also three and more patterned slip stitches, which provides better coverage of the basic fabric of the patterned warp knitted fabric.
  • the pattern threads like the warp threads, are fed and processed continuously and the patterning is done only by means of the controllable thread retainer, a particularly simple method and a correspondingly simple warp knitting machine, e.g. Crochet gallon machine that can deliver high performance accordingly.
  • the process can be carried out with various knitting needles, such as latch needles or sliding needles.
  • the laying direction of the warp threads and the pattern threads can be selected and changed as desired.
  • a method according to claim 3 which allows very high production speeds is particularly advantageous.
  • the thread retainer can optionally be arranged over the extended knitting needles.
  • an embodiment according to claim 4 is particularly advantageous since the thread retainer is then outside both the knitting needles and the thread guide for the warp threads and the pattern threads, and is therefore not hindered by these components and, conversely, does not hinder their functions.
  • An electronic pattern control device is particularly simple.
  • the pattern thread guide can be guided simultaneously over at least two knitting needles per knitting process and cause simultaneous action in at least two slip stitches.
  • an embodiment according to claim 7 is more advantageous which effects an action in only one slip stitch per knitting process, the slip stitches changing from knitting to knitting.
  • the pattern thread guides can have any configuration, for example tube thread guides.
  • an embodiment according to claim 8 is particularly advantageous.
  • Claim 9 describes a particularly expedient embodiment of the warp knitting machine. Such an embodiment is particularly suitable for tongue-less knitting needles according to claim 10.
  • a warp knitting machine enables particularly operationally reliable conditions.
  • the position of the thread retainers can be as desired, but a design according to claim 12 is particularly preferred.
  • the thread retainer can be arranged directly in the area of the knitting needles and can be moved up and down.
  • An embodiment according to claim 13 is more expedient, however, since here the individual components do not interfere with one another and, moreover, the thread retainer can be made more stable. This configuration also allows the thread retainer to be moved laterally if this should be necessary.
  • the warp knitting machine shown schematically in Fig. 1 e.g. Crochet gallon machine has a knitting needle bar 2, in which a row of knitting needles 4 are arranged in parallel.
  • the knitting needle bar 2 moves the knitting needle 4 back and forth in its longitudinal direction.
  • the knitting needles 4 are guided in a knock-over comb 6.
  • the knock-off comb 6 is preceded by a guide plate 8, which forms a guide gap 10 with the knock-off comb 6, through which the finished warp knit 12 is guided to a take-off roller 14, around which it is guided by means of a pressure roller 16.
  • warp thread guides 18 In front of the knitting needles 2 are warp thread guides 18, which are designed as perforated needles and are fastened to a warp rod 20.
  • the warp thread guides 18 carry out a back-and-forth movement in the direction of the kettle rod 20 as well as a swiveling movement from a high position above the knitting needle plane (FIG. 1) to a low position below the knitting needle plane by means of the kettle rod 20.
  • the warp thread guide 18 can thus insert a warp thread 22 into the knitting needle 4 in a movement encircling the knitting needle 4.
  • Pattern thread guides 24 are arranged above the warp thread guides 18 and are also designed as perforated needles.
  • the pattern thread guide 24 is fastened to a pattern thread laying rod 26 which, like the warp thread laying rod 20, carries out an axial movement over at least two knitting needles and a pivoting movement, so that the pattern thread guide 24 is brought from a high position above the knitting needle plane (FIG. 1) to a low position below the knitting needle plane can be.
  • Each pattern thread guide 24 serves to feed and insert a pattern thread 28 into the knitting needles 4.
  • thread retainers 30 are arranged, which can be moved back and forth from a high position shown in FIG. 1 above the knitting needle plane to a lower position indicated by dash-dotted lines.
  • the thread retainers 30 are fastened to guide rods 34 by means of clamping members 32.
  • Such a guide rod 34 is shown excellently in FIG. 1, further guide rods are indicated by dash-dotted lines.
  • a plurality of thread retainers 30 can be arranged on each guide rod and moved up and down in each case by the distance X.
  • the thread retainers 30 In the high position, the thread retainers 30 enable a pattern thread 28 to be inserted into the knitting needle 4.
  • the thread retainers 30 prevent the pattern thread 28 from being inserted into the knitting needle 4, as will be explained in more detail below.
  • the thread retainers 30 are guided up and down in a fixed guide 36.
  • the pattern control device 38 shown in FIG. 2 is used to control the thread retainer 30.
  • FIG. 2 also shows a guide bar 40 in which the guides 36 for the thread retainer 30 are arranged.
  • the guide rod 34 is held via tension members 42 and connected to a control box 44 which, according to a predetermined program, pulls or releases the tension members 42 so that the guide rod 34 can be moved up and down against the force of prestressing springs 46.
  • a front weft guide 48 and a rear weft guide 50 can also be seen in FIG. 1, between which a further thread guide 52 for inserting a rubber thread can be seen.
  • FIG. 3 shows a further pattern control device 54, in which thread retainers 56 are axially displaceably mounted in a guide rod 58.
  • a biasing spring 60 holds the thread retainer 56 against a stop 52 in the illustrated high position.
  • a rocker 66 is connected to the thread retainer 56 via a bolt 64 and is pivotably mounted in the machine frame 68 on an axis 70.
  • a harness cord 72 is attached to the side facing away from the thread retainer 56 and leads to a programmable control device 73, e.g. a jacquard device is guided.
  • the warp knitted fabric consists of individual slip stitches 74 1 to 74 8 , which are each formed from a warp thread 22.
  • the individual slip stitches in each row of stitches are connected to one another by weft threads 76, which are inserted into the stitches of the slip stitches.
  • the slip stitches can also contain inserted rubber threads 78, as is shown for the slip sticks 74 i , 74 2 , 74 3 , 74 7 , and 74 8 .
  • the warp knitted fabric includes a patterned area 79 and unpatterned areas.
  • Pattern threads 28 are used for the patterning, which are inserted into the stitches of a slip stitch where they should not appear, and are therefore covered by the warp stitch stitches, as is shown, for example, for the non-patterned section 80 of the slip stitch 74 4 in FIG. 4 .
  • the individual pattern threads 28 between two Kettmaschenstäbchen such departures are 74 4 and 74 5 and brought hither and each acting in the Kettmaschenstäbchen.
  • the individual stitches of the pattern thread 28 lie above the stitches of the warp thread 22 and thus appear as a pattern on the surface of the warp knitted fabric.
  • the pattern thread 28 forms a stitch 84 and on the slip stitch 74 5 a stitch 86.
  • the knitted threads are always guided in the same direction around the knitting needle 4, which is particularly important in the manufacture of the warp knitted fabric with tongue-less knitting needles, such as crochet needles in particular, is required.
  • FIGS. 5a to 5f show the action of a pattern thread that should be visible on the front of the warp knit
  • FIGS. 6a to 6e show the insertion of the pattern thread if it should not be visible in the warp knit.
  • FIGS Figures 5a and 5c shows the knitting phase in which the knitting needle 4a has been withdrawn and a stitch 88 has knocked off.
  • the thread retainers 30a and 30b are in the up position and the warp thread guide 18 and the pattern thread guide 24 are in the down position below the knitting needle level.
  • the knitting needle 4a is advanced and the warp thread guide 18 and the pattern thread guide 24 move into the high position above the knitting needle level and over the knitting needle 4a and on the other side (in the figures on the right side) again into the low position, as in FIGS Figures 5b and 5c emerges.
  • the warp thread 22 and the pattern thread 28 are pulled through the stitch 88, i.e. knitted into the warp knit.
  • the pattern thread 28 is then visible on the front 90 of the warp knit 12.
  • the warp thread guide 18 again circles around the knitting needle 4a, while the pattern thread guide 24 is shifted to the right to the knitting needle 4b and circles around this knitting needle, as can be seen in FIGS. 5e and 5f.
  • the pattern thread 28 is now inserted into the knitting egg 4b, in which the warp thread 22 (not shown) of the adjacent slip stitch is also located. While the knitting needles are being pulled back and the stitches are knocked off, the pattern thread guide 24 is moved back to the first knitting needle 4a in the lower position and a new knitting phase cycle can begin.
  • FIGS. 6a to 6e show how insertion of the pattern thread 28 into the knitting needles 4a and 4b is prevented.
  • Figures 6a and 6b initially correspond to the active phases of Figures 5a and 5b.
  • the thread retainer 30a is lowered and thus prevents the pattern thread 28 from being superimposed on the knitting needle when the warp thread guide 18 and the pattern thread guide 24 are placed around the knitting needle 4a and are brought into the low position, as can be seen from FIG. 6c.
  • the superior movement of the pattern thread guide 24 compared to the movement of the warp thread guide 18 can be delayed, as indicated in FIG. 6b.
  • the thread retainer 30a is held in the low position shown in FIG. 6c.
  • the warp thread guide 18 is again brought from below around the knitting needle 4a to the left and further into the high position, the pattern thread 28 being inserted into the stitch 88 on the back of the warp knit 12.
  • the pattern thread guide 24 is simultaneously moved to the right to the knot 4b and into the up position, as can be seen in FIG. 6b.
  • the thread retainer 30b is lowered below the knitting needle plane, so that the pattern thread cannot move into the knitting area of the knitting needle 4b when the pattern thread guide 24 moves further around the knitting needle 4b, as shown in FIG. 6e emerges. Since the pattern thread 28 is not gripped by the knitting needle 4b, the pattern thread 28 is also not bound into the slip stitch, which is formed by the knitting needle 4b. When the pattern thread guide 24 returns, the pattern thread 28 is tightened again and guided to the slip stitch, which is formed by the knitting needle 4a, as is indicated for the unpatterned section 80 of the slip stitch 74 4 of FIG. 4.
  • the two knitting cards of FIGS. 5a to 5f and 6a to 6e are combined with one another on the wheels of the patterned area 79, it then being possible for the pattern thread 28 to act on the knitting needle 4a, as shown in FIGS. 5a to 5d.
  • an action of the pattern thread on the knitting needle 4b can be prevented if the warp knitting machine or pattern control device is controlled according to FIGS. 6d and 6e, ie the thread retainer 30b is to be lowered, so that insertion of the pattern thread 28 on the knitting needle 4b is prevented.
  • the pattern thread can be laid one after the other over three or more knitting needles. It is also possible to guide the pattern thread per knitting process simultaneously over two or more knitting needles and to act in the slip stitches in the pattern areas. In particular, features of individual exemplary embodiments can also be interchanged and combined with one another.
