  • Fig. 1 shows schematically the weft entry in a Row shed weaving machine.
  • Four weft threads 7; 71, 72, 73, 74 are made up of four storage units 2a-2d and four Metering devices 1a-1d in the Weft distributing device 9 promoted.
  • the Weft distributing device 9 distributes the delivered Weft threads 71-74 on the respective open shed of the Weaving rotor 100, the weft threads being stationary Fluid nozzles 91, 92, 93, 94 in the rotating weaving rotor 100 can be entered.
  • a sensor 46d monitors this Shooting the weft 74 into the weaving rotor 100
  • Weft threads 71, 72 and 73 were in ascending order Sequence in time in the web rotor 100 shot and are therefore accordingly against the weft arrival end 100b of the weaving rotor 100 registered.
  • the weft 71 is completely in the weaving rotor 100 entered what is recognized by the sensor 46c.
  • a Drive device 104 which drives the weaving rotor serves, is via an axis 106 with the weaving rotor 100 and connected to an angle sensor 105.
  • a fluid line 121 feeds the fluid nozzles 91-94, the fluid flow can be interrupted by valves 120a-120d.
  • All sensors 46c, 46d, 105 and sensors of the metering devices 1a-1d are connected to a control and regulating device 200. Also all actuators like the valves 120a-120d, the drive device 104 or the metering devices 1a-1d via signal lines with the control and Control device 200 connected.
  • the weft 71-74 by the metering device 1a-1d continuously withdrawn from the weft supply 2a-2d and promoted to the weft distributing device 9, which the Weft 71-74 in an open shed 103a-103d directs.
  • the conveying speed of the Weft thread 71-74 when entering the shed 103a-103d determined by the metering device 1a-1d.
  • Thread tip caused by the weft distributing device 9 or the fluid nozzles 91-94 in a new, open one Shed 103a-103d is redirected.
  • the Entry speed of the weft 71 in the shed 103a-103d is in turn replaced by metering device 1a certainly.
  • the control or regulation of the weft thread entry is carried out by the control device 200, which Actuators, for example, the speed of the weaving rotor 100, the insertion speed of the weft, the On and off time of the fluid nozzles, as well as the Fluid pressure determined.
  • the tax or Control device requires a reference value or Guide value, regarding the behavior of the rest Components is matched.
  • the embodiment is, for example, the Angle of rotation or the angular velocity of the weaving rotor 100 as a guide value.
  • This guide value can be from the tax and Control device 200 itself can be specified to Example as a clock signal with respect to which all Components are synchronized. Such a leading value is also referred to as an artificial guide wave.
  • the row shed weaving machine can be controlled by the control and Control device 200 with different methods operate.
