    • D03D47/34—Handling the weft between bulk storage and weft-inserting means

Definitions

  • the invention relates to a weaving machine with a weft supply bobbin remaining outside the shed and an entry element which penetrates the shed during the weft insertion, e.g. Projectile.
  • the weaving machine is to be operated at high speed and, if necessary, sensitive yarns are to be processed, the disadvantage can arise that the weft yarn must be subjected to particularly high acceleration and thus thread stress at the start of entry.
  • the yarn at Entrysenae must be braked strongly and therefore subjected to special stresses.
  • the thread tip can be torn out of the clamp of the entry element under the suddenly occurring high tensile force (thread loser), at the end of the entry, the thread can be crushed in the thread brake under the influence of the relatively high mass force that quickly sets in during braking. In both cases, the web operation can be disrupted.
  • the invention has for its object to provide a particularly improved machine in this regard.
  • the invention consists in that a compressed-air-fed device for influencing the weft movement during the insertion is provided between the supply spool and a point of transfer of the weft thread to the insertion member.
  • the thread can be slowed down in a particularly gentle manner.
  • the device for influencing the weft movement only has to be fed and controlled accordingly with compressed air. In this case too, the thread stress can be reduced.
  • the weft thread 1 is drawn off from a stationary supply bobbin 4 that remains outside the shed 3 formed by the warp threads 2. It first arrives at a drum store 5, then through a delivery device 6 consisting of two rollers running one on top of the other and from here into a blow store 7. This contains a pipe 9 standing transversely to the entry direction 8 and an air nozzle 11 blowing the thread 1 into this pipe a thread loop 12 is blown out.
  • the weft thread 1 is then passed through a deceleration nozzle (brake nozzle) 13 blowing against the entry direction 8, an acceleration nozzle 14 blowing in the entry direction 8, a thread clamp 15, a thread tensioner 17 movable in the direction of arrow 16 and a thread transfer nozzle 18 through which the weft thread 1 with its end 19 aer weft clamp 21 of the projectile 22 is presented.
  • the projectile 22 can by the impact lever 23 in the shed 3 (Web wide W) can be shot.
  • the fabric that arises at the stop 24 is designated by 25, the projectile brake located on the catch side 41 by 42.
  • a control device of the weaving machine now emits a short air pulse from the thread transfer nozzle 18, whereby the thread end 19 is blown into the opened projectile clamp 21.
  • the thread transfer point is designated 20.
  • the thread clamp 21 is then closed and the air pulse of the nozzle 18 is turned off.
  • the impact lever 23 is pivoted clockwise in FIG. 1 and the projectile 22 is shot into the shed 3.
  • an air pulse is given in the acceleration nozzle 14 and the thread tensioner 17 is moved into the position 17a.
  • the projectile 22 flies through the shed 3, the weft 1 is pulled under acceleration through the nozzle 14, the thread loop 12 in the store 7 being used up more or less. If necessary, thread is drawn from the memory 5.
  • the air pulse in the nozzle 14 is switched off and a pulse is given through the nozzle 13 in the direction of entry 8 in the opposite direction. This will slow down the weft.
  • the thread brake 15 is then closed, causing the thread 1 to come to a complete standstill.
  • the projectile 22 is then defined in a Thread release position pushed back, which is exactly the same with every weft insertion.
  • the thread tensioner is moved from the position 17a back to the starting position 17, as a result of which the weft thread is kept tensioned in the shed 3.
  • the thread 1 is cut by a shear 26 on the weft side. Then the sheet of the inserted weft is struck against the tissue 25 by means of the reed 27.
  • a thread guide tube 31 which is only indicated schematically, is arranged instead of the acceleration nozzle 14 and the deceleration nozzle 13.
  • the thread 1 By feeding compressed air into a nozzle 32, the thread 1 can be accelerated, and by feeding compressed air into the nozzle 33, it can be reversed (braked).
  • a controllable thread clamp 34 is installed between the drum store 5 and the blow store 7. It can be closed, for example, during the weft insertion, so that the weft thread length to be entered is removed from the blow memory 7 or the loop 12.
  • terminal 34 is opened and terminal 15 is closed.
  • the nozzle 11 now receives an air pulse, whereby a new loop 12 is formed in the memory 7.
  • nozzle 18 receives an air pulse for thread transfer and a further air pulse when the thread is inserted into shed 3.
  • the device according to Fig. 1 can e.g. are controlled such that the piece of thread that is released when the thread tensioner 17 moves in position 17a is blown back into the loop 12 through the nozzle 13.
  • the drum store 5 can be omitted and only one blow store 7, 11 can be provided.
  • a whole number of different combinations of compressed air-controlled thread influencing parts in the area between the supply spool 1 and the thread transfer point 20 are possible.
  • a compressed air-fed device for influencing the weft thread movement in the described or a similar form can also be used, for example, in a belt rapier weaving machine in which, instead of a free-flying projectile 22, a rapier attached to an insertion banana moves through the compartment 3.
  • the compressed air-fed device is to be used for influencing the weft thread movement during entry for a two- or multi-weft machine, a corresponding plurality of parts 4, 5, 1, 17, 18 shown in FIG. 3 will be installed, such an arrangement for each thread type Corresponding to FIG. 3.
  • the type of thread to be entered in the compartment 3 is then presented to the projectile 22 at the thread transfer point 20 by a multi-shot device.
