Definitions

  • the invention relates to a method and an apparatus for weaving fabrics in general and airbag fabrics in particular.
  • Weaving machines which only allow one method for the insertion of the weft thread into the shed for the production of fabric, in particular airbag fabric.
  • Such methods are based, for example, on air nozzle, belt gripper, rod gripper, double gripper (rod or belt), rifle, projectile or water jet entry technology.
  • the methods offer various advantages, for example high speed and thus high output, the possibility of automating process sequences, for example weft breakage elimination and the like.
  • they also have disadvantages, such as high energy requirements.
  • the so-called "air friendliness" of the yarn also has a strong influence on the production speed.
  • rapier weaving machines cannot achieve the production speeds that are possible with air-jet weaving machines due to the masses to be moved.
  • the entry element in rapier weaving machines is in constant contact with the warp threads and can damage them, particularly with sensitive warp thread materials.
  • the invention is based on the object of proposing a method and a device for weaving and also a woven fabric with which the disadvantages of the prior art are avoided or at least greatly reduced.
  • the object is initially achieved by a method according to claim 1.
  • the method according to the invention advantageously allows weft thread materials to be entered as economically as possible in accordance with their characteristics using the weaving method which is favorable for this purpose. For example, very light materials can be woven at high speed via air entry, while heavy materials can be woven easily, for example, by a gripper entry system.
  • the same advantages result when distinguishing sensitive or robust materials. It is therefore possible to select the optimum entry method in the production of a wide variety of articles and possibly different weft insertion materials arranged therein, and this even during the weaving process with the weaving machine running.
  • an air nozzle and a gripper entry system are used for the method according to the invention for the weft insertion.
  • a device which is characterized in that it has an air nozzle and a rapier insertion system for the weft insertion, which are arranged such that the weft insertion during the weaving process with the loom running from one weft insertion system to the other Weft insertion system can be changed.
  • This "combined" weaving machine is obvious: The previous system-related restriction due to the weft material to be woven is no longer required.
  • this device can be used to weave light, resistant weft threads at very high speed, on the other hand, heavy and / or sensitive weft thread materials can be woven more slowly but equally safely with the looper insertion system during the same weaving process.
  • the device according to the invention when using the device according to the invention, one can see that compared to known devices significantly improved economy. In addition, there is no need to maintain a number of weaving machines with only one weft insertion system. The machine park and the associated costs are lower. The machine utilization of the existing machines is higher. However, it is also possible with the device according to the invention to work with only one of the two systems arranged thereon, for example if the goods to be processed thereon require the use of only one of the two systems. The device according to the invention thus actually represents three machines. First, an air jet weaving machine, then a rapier insertion machine and finally the combination of these, an air nozzle / rapier insertion machine.
  • Figure 1 shows a very schematic view of a weaving machine with a device according to the invention in a perspective view.
  • Figure 2 shows a very highly schematic, top view of the assignment of two weft insertion systems on a weaving machine to one another in the two operating positions, viewed in the weft direction.
  • FIG. 1 shows a weaving machine 1 on which elements for the air and rapier insertion weaving methods are arranged.
  • a weft thread can optionally be used with the machine 1 running .
  • a weft cutter 13 cuts all the inserted weft threads 23 and 43, respectively.
  • the weft thread 23 remains in position for the gripper entry after insertion and cutting after the sheet stop, it is held by a weft thread clamp 26.
  • the gripper 22 remains in its outer position shown in FIG. 1.
  • a holder 45 for the air intake is shown cut off in Figure 1. It carries main nozzles 41 for the air entry, wherein in FIG. 1 a weft thread 43 which has already emerged from one of the main nozzles 41 over a short distance can be seen for the air entry. When air is introduced, the weft thread 43 further conveying relay nozzles 42 are shown mounted on the weaving machine 1. As can be seen from FIG.
  • the holder 45 for the air intake can be rotated in an exemplary manner with an axis that penetrates vertically about a plane of the drawing, connected to a sheet drawer 12 with a drive, into the two positions shown in FIG. 2.
  • the holder 45 for the air entry and the main nozzles 41 thus held for the air entry in the rest position are shown, while the main nozzles 41 and with them the holder 45 for the air entry are on the right side in the working position.
  • FIG. 2 does not show the gripper 22, but a gripper guide 25 in which the gripper 22 runs.
  • the gripper 22 remains outside the weaving area of the weaving machine 1 during the working phase of the air nozzle entry system 4, that is to say the working position of the holder 45 for the air entry.
  • FIG. 1 shows a thread transmitter 21 for the gripper entry, which presents a weft thread 23 for the gripper 22.
  • the weft thread 23 is held in position by a weft clamp 26 for the gripper insertion.
  • a fabric 50 is shown schematically on the right side of FIG. For reasons of clarity, only the first two pairs of warp threads are fully executed. However, it is easy to see the compartment opening into which the respective weft insertion system delivers the corresponding weft. With the device according to the invention just described, it is now possible for the first time that two weft insertion systems can be used alternately or in parallel on a weaving machine 1.
  • the use can be changed when the weaving machine 1 is standing or running.
  • the weaving machine 1 described here can be operated in three different ways of working, firstly as a pure air jet machine, secondly as a pure rapier machine and thirdly as a combined air jet and rapier machine.
  • weft insertion systems can be used on a weaving machine, using the example of an air nozzle entry system 4 and a rapier entry system 2.
  • the range of different weft insertion systems that can be used is larger than the present device in the exemplary embodiment shows.
  • the gripper machines are belt grippers, bar grippers and Double grippers (rod or belt) are also conceivable, as in the other systems contactor, projectile or water jet entry systems could be combined.
  • the combination or the possibility of sensible use of different weft insertion systems depends on the goods to be produced and the weft materials required for this.

Abstract

L'invention concerne un procédé et un dispositif de tissage en général, et en particulier pour fabriquer des tissus pour sacs gonflables. L'invention est caractérisée en ce que les fils de trame (23, 43) sont insérés dans le métier à tisser (1) par différents systèmes d'insertion de trame (2, 4) montés sur le métier à tisser (1), le passage d'un système à l'autre se faisant pendant le tissage, lorsque le métier à tisser (1) est en fonctionnement.
