Definitions

  • the invention relates to a method for entering a Weft into a row shed loom with a Feed nozzle and a weft distributing device, wherein the weft thread by means of a fluid flow fed continuously and in successive Shed is entered as well as a device for Carrying out the method with a feed nozzle and an entry nozzle and one Weft distributing device.
  • weft threads are made using a weft distributing device entered.
  • a such a device is described in WO 96/38612.
  • a weft thread is by means of a continuous air flow into a connecting duct inserted between the weaving rotor and a ring part and entered into a shed via a shooting tube.
  • a Cutting device and a clamp are the Subsequent shooting tube. Immediately after The weft is stopped by the clamp a loop due to the continuous delivery of yarn formed in the connecting channel after cutting the weft is stretched.
  • the invention as characterized in the claims is the object, a method and a device for inserting a weft into a Row shed weaving machine to improve.
  • a Weft thread 1 is based on a thread store a metering device and the one in question here Weft insertion device 2 in one Weft distributing device 3 initiated and then past a cutting device 5 and one Thread clamp 6 in a formed on a weaving rotor 7 Shed entered.
  • the weft insertion device comprises a feed nozzle 11, a nozzle arrangement 12 and an entry nozzle 13 which in the Weft distributing device 3 is arranged.
  • Of the Entry device is also a guide member 14 and Auxiliary nozzle 15 assigned.
  • the nozzle arrangement 12 is with a rotary slide valve 16 via lines 17 with the Compressed air system connected to the weaving machine.
  • the nozzle arrangement 12 has a body 21 with a through hole 22 and two seat surfaces 23 and two nozzle needles 24, 25, which are arranged so that the mouths face each other.
  • the Nozzle needles are designed as hollow needles, so that a continuous conveyor channel for a weft in the Nozzle arrangement is present.
  • On one nozzle needle 24 is an inlet funnel 26 for the weft trained while the other nozzle needle 25 directly with the insertion nozzle 13 in the weft distributing device 3 connected is.
  • the weft thread 1 is fed by means of the feed nozzle 11 continuously withdrawn from the metering device and in introduced the nozzle needle 24. At this time due to the setting of the rotary slide valve 16 Compressed air through line 17 of the nozzle arrangement supplied so that an air flow in the through hole 22nd is generated, which detects the weft and for Entry nozzle 13 transported. The weft is then in the shed and shot in a known manner of the traveling field generated by the relay nozzles promoted the shed. Before inserting the Clamping takes place by means of the rotary slide valve the reversal of the air flow in the nozzle arrangement 12, so that a thread pull in the opposite direction to Direction of conveyance is generated.
  • the weft continues into the shed registered. If the weft thread is clamped, it is omitted Power share of the hiking field, so that the of the Entry nozzle in the conveying direction and the nozzle arrangement cancel thread tension generated in the opposite direction, i.e. the weft feed into the shed interrupted. Because of this interruption and continuous weft feed from the feed nozzle 11 is a thread loop between the feed nozzle 11 and the nozzle assembly 12 generated. After clamping, the Cut the weft and use the injector nozzle blown the connection channel 4 and the Weft tip essentially stretched and to the Entry in the weft distributing device 3 ready held. By means of the rotary slide valve 16, the Flow direction in the nozzle arrangement 12 again vice versa, so that the thread loop is lifted and the Weft thread is entered in the next shed.
  • the Weft insertion device 31 comprises the feed nozzle 11, a deflecting member 32, an insertion nozzle 33 and one Auxiliary nozzle 34.
  • the deflection member 32 is rod-shaped formed and pivotable about an axis of rotation 35 arranged.
  • the weft thread 1 is fed by means of the feed nozzle 11 continuously deducted from the metering device and on the deflection element 32 past into the entry nozzle 33 introduced. At this point the entry nozzle Compressed air supplied and from the weft into that Shed shed. The weft is then in known manner by means of the relay nozzles through the Shed promoted. With the actuation of the thread clamp 6 the weft is held and the Weft feed interrupted in the shed. Because of this interruption and the continuous Weft feed from the feed nozzle is positive Deflection by means of the deflection element, a thread loop between the feed nozzle 11 and the feed nozzle 33 generated.
  • the weft is made using the cutting device 5 cut and the formed Thread tip through the air flow in the Blown in connection duct 4.
  • the through the Air flow on the weft applied force acts on the one hand as a restraining force with regard to the Loop formation and on the other hand as a stretching force for the Thread tip.
  • the weft thread 1 clamped and held by means of the thread clamp 42 so that on the one hand between the feed nozzle 11 and the thread clamp 42 forms a thread loop and on the other hand means the cutting device 5 generated thread tip stretched for entry in the weft distributing device is kept ready.
  • the loop formation can be done by means of an active or passive deflection movement become.
  • a weft thread is made using a Fluid flow continuously supplied and in successive web subjects entered.
  • the flow direction or deflection of the weft becomes a thread loop outside the Weft distributing device formed, whereby the Weft thread inside the weft distributing device stays stretched.
  • a nozzle arrangement is used to carry out the method 12 provided, the flow direction is reversible.
