Definitions

  • the invention relates to a weaving machine with a rapier which consists of at least one rapier head and a rapier guide means and slides on a rapier track during the weft insertion, magnetic means for stabilizing the rapier being provided in the rapier track and in the rapier.
  • the gripper guide means has at least one insert made of magnetic material in the immediate vicinity of the gripper track, and consists of plastic with a groove for receiving the insert.
  • the remaining parts of the gripper and the gripper guide means can be made of light metal or plastic by a special section made of magnetic material without magnetic properties.
  • FIG. I seen from the goods side.
  • the gripper drives 4 and 5 are fastened to the frame 2, which rotate according to the arrows shown and move the grippers 100 and 110, consisting of gripper heads 10 and 11 and gripper guide means 15 and 16, into the area along the reed 7.
  • the weft thread would be drawn in by the hook head II from the right between the warp threads and transferred in the middle of the weaving machine to the hook 10 for complete entry over the entire weaving width W.
  • the finished fabric 3 is picked up by the fabric tree 6, which is stored in the machine frame 2 .
  • the gripper guide means 15 and 16 are shown as bands which are supported by the gripper track 8. 2 and 3, two magnets 12 and 13 are embedded in the gripper track 8. They can be made from permanent magnet steel.
  • the grooves are dovetail grooves, as shown in Figs. 3 and 4, into which inserts of magnetic material, e.g. Soft iron with a cross section corresponding to that of the grooves 18 are inserted through the recesses 19.
  • the insert 17 can also consist of plastic with embedded metal particles or a plastic magnet.
  • the track 8 must be made of non-magnetic material. Instead of magnets 12 and 13, pieces of soft iron must then be used.
  • the magnets 12 and 13 and the inserts 17 made of magnetic material are dimensioned and arranged in such a way that the effect of a magnet on the respective insert on the movement range of the grippers 100, 110 is limited shortly before and during their interaction.
  • the recesses 19 can be filled with synthetic resin after inserting the inserts 17. It is expedient to arrange the magnets 12 and 13 or the inserts 17 such that they lie one above the other shortly before the gripper heads 10 and II meet. In this way, the gripper heads 10 and II are at the right moment by ver relatively weak magnetic forces, which act on the inserts 17 from the magnets 12, 13, are aligned with one another.
