  • Rotary devices are used to form fabric edges: One Pierced needle, which runs a warp thread in an eyelet, and a driving needle in combination with a weft thread form a leno weave (see e.g. B. EP-A 0 737 764).
  • the needles are moved with drive units, the cables, control cams, rollers and levers in known weaving machines include. These mechanical components are expensive and weary. In the event of changes in operating parameters (strand stroke, sugeometrie u. a.) Time-consuming manual adjustments be made.
  • the object of the invention is to provide a further device with which Warp threads - especially to form fabric edges - by means of a punctual forced control (i.e. with selective means) controlled are movable and in which the disadvantages mentioned are eliminated.
  • This task is solved by the device defined in claim 1.
  • This device moves in a controlled manner by means of selective forced guidance a warp thread between three positions, namely a middle one upper and a lower position. It includes one around an axis pivoting pendulum, in which an electrical coil is integrated, and fixed permanent magnets. Through equilibrium of the pendulum the specified positions are given, in which positions forces, that act on the pendulum are in equilibrium.
  • the Equilibrium positions for the upper and lower positions are by means of Forces between the permanent magnets and the current-carrying coil producible; the equilibrium position for the middle position is through that Given pendulum with de-energized coil.
  • Objects of Claims 10 to 12 are a loom with such a device and uses of this device for a lathe device and for a jacquard shedding device.
  • a device 1 for the controlled movement of a warp thread 9 comprises the following components: a pivotable about an axis 20 Pendulum 2, in which one on a non-ferromagnetic sheet 21 or Electrical coil 3 arranged between two such sheets 21 is integrated is; Permanent magnets 4 on a fixed support plate 7; vertical Slidable elements 5 and 5 ', the flexible bands 6 and 6' in Operational connection with a bracket 22 of the pendulum 2; and springs 65.
  • the straps 6 and 6 'serving as traction means can also be used as ropes be trained.
  • the middle position is due to gravitational forces and on the other hand, tensile forces of the springs 65 are given.
  • the one direct current leading coil 3 generates together with the permanent magnet 4th in addition magnetic forces, through which the equilibrium position changes right or left shifted. By reversing the polarity of the current in coil 3 the pendulum 2 changes from one to the other of these two Equilibrium positions.
  • the tape 6, which is on the lower side 23 of the The bracket 22 can partially rest on the side with a screw 62 Pendulum 2 is attached and that via a roller 61 in the vertical direction is deflected, the pendulum movement sets in a linear movement of the Elements 5 ⁇ m.
  • the equilibrium positions of the pendulum 3 are transferred thus to three stable positions of the eyelet 50 through which the three named Positions of the warp thread 9 are given. Sensors for a regulation these positions are not necessary.
  • the strip-shaped or groove-shaped contact surface 23 for the traction means 6 advantageously lies on a curve that is at least approximately a circle around the Pendulum axis 20 is. In particular, on the center of this circle the pendulum axis 20 are.
  • the stroke of the eyelet 50 i. H. the Distance between their middle and upper (or lower) position, proportional to the radius of the named circle.
  • the hub is also proportional to the swivel angle of the pendulum 2, which is determined by the position and Shape of the magnets is fixed.
  • the device according to the invention In contrast to linear motors, the device according to the invention must the weight of the movable part, namely the pendulum 2, not by electromagnetic forces are absorbed.
  • the pendulum 2 is a segment plate made of a non-ferromagnetic Material in which the coil 3 (with connecting wires 30) is embedded.
  • the Deflection rollers 61, 61 ' have horizontally displaceable axes.
  • a second Pair of rollers 63 has axles with fixed positions.
  • a side view of a pendulum 2, as in the device 1 of FIG. 1st 4 shows a configuration of permanent magnets 4, 4a for this pendulum 2, which are arranged on the carrier plate 7, is in FIG. 5 shown; and a horizontal cross section through this pendulum 2 with the Permanent magnets 4, 4a arranged on both sides is shown in FIG. 6 shown.
  • the electrical coil 3 is designed as a flat ring.
  • the one with the coil 3 The magnetic field that can be generated is at least approximately parallel in the center of the ring oriented to the pendulum axis 20.
  • the permanent magnets 4, 4a are disc-shaped and arranged parallel to the coil 3.
  • the Magnetizations of the permanent magnets 4, 4a are the same as the one mentioned Magnetic field of the coil or oriented opposite to this.
  • the Permanent magnets 4, 4a are advantageously on both sides of the pendulum arranged ferromagnetic carrier plates 7 and each form the same Configuration. 6 are the magnetizations of the permanent magnets 4, 4a indicated by arrows 41, 42. Arrows 47 represent a magnetization of the ferromagnetic carrier plates 7.
  • the two neighboring Permanent magnets 4 and 4a are in the reversal area of the pendulum 2 arranged; they have oppositely oriented Magnetizations.
  • the smaller partner 4a of this permanent magnet pair serves as a brake magnet for the pendulum 2. With this it is achieved that the Pendulum 2 quickly into the upper due to a dampening effect Balance positions remain calm. This also ensures Permanent magnet pair 4 and 4a a more precise reversing or end position of the pendulum 2.
  • the sheets 21 are made made of a material that conducts electricity well but not ferromagnetic is.
  • Aluminum for example, can be selected as the material. Eddy currents in these sheets 21 when moving in the magnetic field Permanent magnets 4, 4a are induced, dampen the movement of the Pendulum 2.
  • a gap 24 is provided so that not by induction when switching the coil current on or off Ring current forms, which would mean unnecessary energy dissipation.
  • an eyelet 50 is provided Strand 5 controlled, at both ends of the tapes 6 and 6 'attack.
  • the Band 6 ' is deflected by rollers through 180 °.
  • the not shown warp thread (or group of warp threads) with a Element 51 moves, its weight increases when the middle position is set is taken into account.
  • the springs 65 and 65 ' can be selected and adjusted in this way be that the pendulum 2 in a non-energized coil 3 in one Equilibrium is in which, for example, the focus of the Pendulum is located vertically under axis 20.
  • Half-turn devices 8 and 8 ' By means of a first device 1 Warp thread 9 'moved with a needle 5.
  • a hook needle 5b (with a Double hook 51) with the perforated needle 5 in a known manner cooperates, is operated with a second device 1 '.
  • This second device 1 ' are simultaneously elements 5a and 5a' which Wear auxiliary edge shafts 55, 55 ', up and down in an opposite manner emotional.
  • the pendulum 2 'of the device 1' comprises two segment plates 2a, 2b with different radii.
  • the hook needle 5b stands with the segment plate 2b associated with the larger radius. Accordingly there is a greater stroke than for the auxiliary edge shafts 55, 55 '.
  • a fixed Plate 80 - see also the oblique image in Fig. 10 - is between the Half-turn elements 8 and 8 'arranged. By edging this plate 80 necessary deflections of the warp threads 9 result in a known manner and 9 '.
