Definitions

  • the device according to the invention for introducing a weft thread into a shed of a weaving machine comprises a thread store, a conveying device for inserting the weft thread into the shed, and one or more measuring sensors.
  • the conveying means includes at least one accelerating nozzle to accelerate and feed the weft yarn drawn from the yarn store to the shed, and a plurality of auxiliary nozzles to feed the weft yarn in the shed.
  • the acceleration nozzles comprise a main nozzle 3 and a tandem nozzle 4, which are each supplied with compressed air via a control valve 13, 14, for example a solenoid valve.
  • a control valve 13, 14, for example a solenoid valve for example a solenoid valve.
  • the main and tandem nozzles 3, 4 may also be provided only a single main nozzle, or it may be several consecutive nozzles, often referred to as pre-nozzles and main nozzles, arranged one behind the other to accelerate the weft.
  • a plurality of juxtaposed and / or superimposed main nozzles 3 may be provided to alternately enter different weft threads 2, which may differ in color, fineness, texture and material.
  • optical and electrostatic methods are also known in which each of the signals of two arranged along a thread spaced sensors are evaluated and from the distance of the transducer and the time shift between the two signals, the speed of the thread is determined.
  • Such an electrostatic process is for example in GB 1 249 610 disclosed.
  • One suitable electrostatic transducer for correlation method is eg in DE 44 08 312 A1 described.
  • the values determined during the weft insertion are used to control and / or control the weft insertion, advantageously the current weft insertion, for example by controlling a yarn brake and / or controlling the on and off timing of the acceleration and / or auxiliary nozzles in an air jet loom and / or, for example, in the case of deviations of a measured velocity profile from a desired profile, a pressure with which the nozzles are acted upon is varied.
