  • the angular positions of the Waves known by angle sensors arranged on the shafts Type of detection and by means of the signals emitted by them the power supply to the electric motors that drive the shafts to control so that the desired mutual phase relationships the angular positions of the shafts can be reached.
  • control loops can be used based on the a target / actual comparison. Such control loops are generally known and need not be explained here.
  • a particular advantage of the solutions described above is that the adjustment of the stroke of the horizontal movement of the needle bar while the machine is running and therefore time-saving, without any disassembly, and can be carried out continuously can.
  • the scraper 8 and the pad 9 for the nonwoven web of the horizontal movement component of the Needles take into account.
  • the stripper 8 which consists of a Perforated plate consists of the holes for the passage of the Needles 7 are therefore designed as slots that extend in the direction the horizontal movement component of the needle bar 4 extend.

  • FIG. 5 schematically shows a plan view of the needle bar area a needle machine. Needle machines sometimes have a lot large working widths that can be several meters. To the to avoid adverse influences of inertia, which too elastic deflections of the needle bar could result, if the force attack on the needle bar only at one point 5, it is provided that the horizontal Movement component of the needle bar at several along its Extension is distributed places. 5 are elements corresponding to the examples explained above provided with the same reference numerals so that they are not repeated here need to be explained. You can see that from the hinge point 15 of the coupling bridge 12 starting from the eccentrics 18th and 19 caused movement via a wishbone 25 and several rocker arms 26 and a corresponding number of trailing arms 27 is transferred to the needle beam carrier 4. This construction principle can be easily based on the embodiment Fig. 3 transferred.

  • this tracking movement has a horizontal direction a speed curve that is sinusoidal, i.e. the Horizontal speed of the needle bar gradually decreases from zero increases, reaches a maximum and then decreases again to zero then the direction for the return movement of the needle bar to reverse, etc.
  • speed of the horizontal movement of the needle bar carried needles on the speed of the feed movement the nonwoven web penetrated by the needles, which in particular Cases when, for example, felts of special fineness and Uniformity, such as paper machine felts, to undesirable disturbances in the structure of the manufactured product.
  • the invention proposes a further development before, the servomotors of the second drive device in one to control the cyclically running program in such a way that the aforementioned sinusoidal velocity profile of horizontal movement of the needle bar at least in that horizontal movement stroke, which follows the direction of web advance to a uniform one Speed is smoothed.
  • Modern control electronics allows the speed of rotation of servo motors in this Way to influence.
  • the feed machine directly assigned to the needle machine To dispense with discharge rollers or between the roller pairs formed column wider than the thickness of the nonwoven web to make and therefore the nonwoven web alone with the help of needles pierced into it by the from the second Drive device caused horizontal movement of the To move the needle bar through the needling zone.

  • sinusoidal course of the horizontal movement of the needle bar is even an advantage in this case because it creates a "Plucking" on the nonwoven web through the needles when accelerating is prevented in the horizontal direction.
  • the complete Adjustment of the needle movement in the horizontal direction to the Enabling respective needs will result in a significant increase in quality of the manufactured product.
  • Another Increase in quality by comparing or blurring the stitch pattern can be achieved if the needle bar between successive stitch movements laterally, i.e. across to the fleece feed direction by less than one lateral Needle spacing is offset.

  • the range of motion that must be produced by the actuator 52 is relative small. According to a lateral distance between each other adjacent needles is usually about 3 mm he just a little less than 3 mm. This range of motion is appropriate divided into several, for example two stages, so that each needle is between three lateral positions is adjustable, a left, a middle and a right Position, seen in the direction of web advance. These positions can be used cyclically, for example either after every needle insertion or after a predetermined one Number of needle punctures in the nonwoven web Position is changed using the servomotor 52.

  • the control of the servomotor 52 can expediently via a control generator 53 take place, which processes a cyclically running control program or a stochastic random sequence of control commands for the servomotor 52.
  • FIG. 6 Another possibility, which is shown in Fig. 6, consists of the actuator being driven by an eccentric drive two eccentrics 54 synchronized by independent drive motors 55 are driven and their connecting rods 56 at the ends a coupling bridge 57 are coupled to each other to form.
