Definitions

  • the present invention relates to a method for inserting weft thread ends on a weaving machine with additional weft effects.
  • a method of weaving patterning and a weaving machine for producing fabrics having such auxiliary shot effects show the patent applications WO 2012004021 A2 and DE 10 2010 007 048 A1 .
  • the process for fabric production according to WO 2012004021 A2 Is characterized in that an effect thread is positioned above the weft thread to be introduced and thereby emerges in the vertical direction from a one-sided upwardly open Rietlücke formed by reed teeth. After a shift of the effect thread in the weft direction of this is positioned below a next to be entered weft thread and immersed in another similarly formed Rietlücke.
  • a guide means of the effect thread is moved in the vertical direction and in the weft direction.
  • the loom according to WO 2012004021 A2 includes a displacement drive, which drives a displacement device in the weft direction, on which at least one guide means is provided, with which an effect thread can be moved in the weft direction and positioned vertically.
  • Object of the present invention is to provide a method by which tissue can be produced with additional bullet effects and good quality of the insert edge.
  • the shed is formed by shed-forming means which vertically move warps in a known manner.
  • a weft thread is selected by means of weft selection means before each weft insertion.
  • the weft selection means may be electromechanical or electropneumatic means well known to those skilled in the art.
  • weft insertion means are present on the weaving machine. These may be already known mechanical or pneumatic weft insertion means. The first weft thread is struck by a Webblatt worn to a fabric edge.
  • the damaged first weft thread is then held in a certain position with holding means for the weft thread in the region of the fabric edge.
  • holding means may be, for example, mechanical thread clamps or thread guide elements. However, it can also be used air nozzles that hold the thread in a specific position.
  • the holding means is provided with a mechanical or pneumatic control. These can be, for example, cam gears, linear motors or pneumatic valves for controlling air nozzles.
  • the insert means may be a loading needle with thread hook or thread eyelet. However, it can also be provided an air nozzle, which detects the first weft end by means of an air jet.
  • the first weft thread end is then inserted into the shed.
  • the method further provides that a second weft thread is selected by means of the weft selection means.
  • the second weft thread is entered into the shed with the weft insertion means. Subsequently, the second weft thread is struck by means of Webblatt celebrating together with the first weft end to the fabric edge The battered second weft thread is then held with the holding means for the weft thread in the region of the fabric edge in a certain position. After the weft insertion - ie immediately before or after the reed stop - the position of the warp threads with the help of the shedding means changes from top to bottom - a new shed is formed.
  • the second weft thread reaches a position in which it is cut with the help of the weft cutter. The result is a second weft end, which is then detected by the insert.
  • the second weft end is then inserted into the shed.
  • the method is characterized in that between the two successive weft insertion operations of the first and second weft thread another reed beating takes place by the Webblatt worn, but no weft thread is struck against the fabric edge. This is achieved in that after the previous Webblattanschlag no additional weft thread is entered into the shed.
  • the weft selection means are controlled so that no weft insertion takes place for a cycle of movement of the loom. There is thus a motion cycle with a so-called empty shot in the process. As a cycle of motion of the loom here the period is referred to, which lies between two Webblattanangen.
  • the main drive shaft of the loom makes a full turn.
  • the inventive method further provides that between the two successive weft insertion operations of the first and second weft yarn extending in the warp direction effect yarn is moved in the weft direction of the loom.
  • the weft direction is the direction in which the weft thread is entered.
  • the method according to the invention thus also encompasses a method in which a continuous change between empty shots and normal weft insertion takes place over a large number of weft insertion, wherein no weft thread end is inserted into the sheds into which no weft thread is inserted.
  • a displacement device already known from the prior art can be used with a guide means for the effect thread for the displacement process.
  • the weaving pattern including the shifting operation and the loading operation can be performed by means of data sets via a control of the weaving machine according to, for example, FIG WO 2012004021 A2 be made.
  • the pattern-controlled activation of the holding means for the weft thread can be realized by the insertion of additional data in the sample cartridge of the respective tissue.
  • the holding means are controlled so that the weft thread can not be cut and detected by the insert. This can be done for example by the control of electromagnetic means in the cam gear. It can be lifted, for example by an electromagnet which acts on the roller lever of the cam gear, the roller of the cam gear as needed in the weave pattern of the cam.
  • the weft thread with the holding means remains in a position on the fabric edge, in which it can not be detected by the insert.
  • the insert means itself-for example a cam gear controlled by a loading gear - can thus also run in the empty-shot mode - ie without weft insertion, without a weft end being inserted.
  • FIGS. 1 and 2 show in partial views of a loom for performing the method.
  • the weaving machine includes shed drives 9 for driving shed forming means 4, by the vertical movement of which a shed 1 1.1.1.2 bounded by warp threads 1 is formed.
  • the shingles 9 known to the person skilled in the art can, for example, consist of a group of levers and rods which are arranged below the shed forming means 4 and which transmit the drive movements of a shedding machine 23 to the shed forming means 4.
  • the shed forming means 4 consist in the present example of known heddles with strands, through the Litzenaugen the warp threads 1 are performed. Furthermore, facilities for the entry of a weft thread 3 in the shed 1.1,1.2 in a weft direction 12 are present.
  • a device is shown with grippers, which are pushed in a known manner via not shown gear and two drive wheels from both sides of the loom in the shed 1.1,1.2.
  • the weft thread 3 is fed in this embodiment of a shot coil on a Vorspuler and a selection device for the Schussfadenart 19 one of the two grippers and transferred to the other gripper in the machine center.
  • weft selection device for the type of weft thread 19.
  • the control device 8 of the loom is further equipped with input means 21 and storage means 22.
  • weft insertion devices may also be designed as weft protectors, projectiles or pneumatic weft insertion devices.
  • a Webblatt Nurs 7,7.1,10 for striking the weft thread 3 to a fabric edge 13 is present, which consists of a Webblattlagerung 10 with reed teeth 7 and a Rietbund 7.1.
  • These reed teeth 7 form between one side upwardly open receiving spaces, so-called Rietlücken 14, so that threads in the direction of the warp threads 1 from back to front through the Loom running, dip from above into these Rietlücken 14 and thus can be performed by the reed teeth 7 in the weft direction 12.
  • reed teeth 7 are attached via the reed collar 7.1 to the Webblattlagerung 10 and perform together with this at each cycle of the weaving machine a stop movement 15 - 15.1.
  • a displacement device 5 with a prismatic guide mounted on the frame of the heald are attached to the three guide means 11, with which three effect threads 2 can be moved in the weft direction 12 by the path A.
  • needles with eyelets 18 are used in the present embodiment, one or more of which are attached at one end to a needle bar.
  • This needle bar forms together with a running in the weft direction 12 prism-shaped linear guide the displacement device 5, which is fastened together with an electric motor drive as a displacement drive 6 at the front of a heald.
  • a displacement drive 6 a linear drive is provided, the stator is integrated in the frame of the heald or in the prism-shaped linear guide.
  • displacement drive 6 which drives the displacement device 5
  • displacement paths A of the effect threads 2 can be predetermined in each movement cycle of the weaving machine.
  • the respective displacement A is derived via a control device 8 and the displacement drive 6 for each movement cycle of the loom of a data set.
  • a computer program which runs in the control device 8 calculates the displacement paths A from the data records.
  • Values for controlling the weft selection means and the means for holding and inserting the weft threads can also be stored in the data records.
