Definitions

  • the invention relates at least to a manufacturing plant a knitted band with crocheted rubber threads according to the generic term of claim 1.
  • a bare rubber thread is wound on a wrapping machine. It is a costly process that is carried out on expensive and noisy machines.
  • a Another procedure is a bare rubber thread to crochet using a separate crochet machine. Although this process is somewhat cheaper than the spinning process, however, it is still in terms of the procedure and the device is expensive.
  • there is a major disadvantage of the crochet process in that that the number of stitches per unit length of the pre-crocheted Rubber thread with the corresponding number of stitches of the finished Knitted band should be matched, due to the elasticity of the rubber thread is difficult to reach. Since that Knitting tape and the crocheted rubber thread in time and place are produced separately, there are also problems with the color matching of the crochet thread and the thread of the Warp fringes of the knitting band.
  • a third possibility is given by the fact that knitting tapes Made with bare rubber threads and one at the same time Is melted across the width of the band.
  • the disadvantages of this method include the high one Price of the additional filament, the additional Melting treatment and in that for guiding the filament an additional shot bar is required.
  • the object of the invention is a system of the aforementioned Art so that the disadvantages mentioned be avoided.
  • the task is set when creating the above Kind by the characterizing features of the claim 1 solved.
  • a crochet device with enveloping needles, Coil thread layers and rubber thread layers is assigned, that will Crochet the elastic thread in sync with the same operation the production of the knitting band online on the same Plant carried out.
  • the rubber threads are timely in the necessary for the working of the knitting band Amount and presentation provided, moreover the guidance of the crocheted rubber threads to the band knitting device is done very precisely, so that a high quality Manufacture knitting tape in a simple and inexpensive way leaves.
  • Knitting tape is of optimal quality because it crocheted rubber thread holds non-slip and once through the own crochet of the elastic thread and the additional Connecting fringe.
  • the elastic thread also does not jump inward, but instead essentially remains in its position.
  • the facility is also particularly simple, because for wrapping and working the Same principles apply so that the components and drives in a simple way let combine.
  • the system can be designed so that your only one knitting band is produced, is more advantageous however, the usual embodiment according to claim 2, after which there are several belt knitting devices in one system, which have a corresponding number of active bands at the same time produce.
  • the production the crocheted elastic threads and the knitting bands are done So synchronously, with only the feeding of the crocheted Rubber thread to the belt knitting device around the deflection section staggered.
  • the rubber thread guide of the The crochet device can be attached to a separate laying bar be arranged or according to claim 4 on the same laying bar like the rubber thread guide of the band knitting device, so that both thread guides make exactly the same movements.
  • a separate take-off device can be provided for the crochet device be.
  • an embodiment is particularly advantageous according to claim 5, after which for the band knitting device and the crochet device the same take-off device is used.
  • Claim 6 describes a further advantageous embodiment the system, after which the crochet device of the tape knitting device is upstream.
  • Both devices can be provided with separate drives, preferably have but a common drive.
  • the drive can do so be configured that the crochet device and the tape knitting device work exactly synchronously and therefore the same Make number of stitches per cm. If necessary however, the gear ratio of the drive to the crochet device be changed so that the crochet one different number of stitches per cm than the knitted tape produced having.
  • the feeding of the crocheted rubber threads to the Belt knitting device can be made in direct connection or preferably by means of a transport device according to claim 7. This allows the supply of the crocheted rubber thread to the tape knitting device controlled more precisely and preferably the pretension of the rubber thread is set separately become.
  • the crochet device is advantageous arranged according to claim 9 above the tape knitting device.
  • a configuration of the system according to is particularly advantageous Claim 10, wherein the crochet device is a rubber thread feeder with preferably adjustable belt tension is assigned so that the elastic thread one for the knitting process Suitable pre-tension is given at the belt knitting station can be.
  • the warp threads for the band knitting device and the covering threads for the crochet device can be by means of separate Thread feeding devices are fed. Particularly advantageous is, however, an embodiment according to claim 11, according to the threads are arranged on a common warp beam.
  • Figures 1 and 2 show a rubber thread 2 made of natural or synthetic rubber material. Of the Rubber thread 2 is crocheted with a crochet thread 4. Of the Crochet thread 4 forms a fringe, the stitches 6 the Include rubber thread 2.
  • the elastic thread 2 crocheted in this way is designated as a whole by 8.
  • FIG 3 shows a crocheted rubber threads 8 of the Figures 1 and 2 manufactured knitting tape 10 in the cutout and in cross section.
  • the crocheted rubber threads 8 are by means of Weft threads 12, 14 connected to one another, connecting fringes 16 from warp threads 18 the connection between the Weft threads 12, 14 on the individual crocheted rubber threads 8 produce.
  • a belt knitting device 20 shown in FIG. 4 and one in FIG Figure 5 crochet device each form one Part of a plant for the production of a knitting belt 10 with bound crocheted rubber threads 8.
  • the tape knitting device 20 and the crochet device 22 are in pairs arranged side by side.
  • a system can Production of a single knitting belt 10, then only a band knitting device 20 and a crochet device 22 are present, or for simultaneous Production of several knitting tapes, so that a corresponding one Number of belt knitting devices 20 arranged in pairs and crochet devices 22 arranged side by side are, as in FIG. 6 using the example of a warp beam 24 is indicated that for the simultaneous production of five Active tapes 10, 10a, 10b, 10c, 10d is used.
  • the warp beam 24 provides the band knitting devices arranged in pairs 20 and crochet devices 22 each warp threads 18 for Production of connecting fringes 16 and crochet threads 4 for crocheting the rubber threads 2 according to Figures 1 to 3 Manufacture of the knitting tapes available.
  • the belt knitting device 20 shown in FIG. 4 is more common Construction and includes a reciprocating beam 26, are attached to the knitting needles 28, which are on a Support tee bar 30.
  • the tee bar 30 forms together with a guide bar 32 a guide gap 34 for pulling off the knitting tape 10 by means of a pulling device 36.
  • the take-off device 36 contains two rollers 38, 40 from one of which is driven and via which the knitting belt 10 withdrawn and led to a winder 42.
