Definitions

  • the invention relates to a tufting needle, consisting of a piston that at least can be partially molded into a needle module, and a shaft that has an eyelet Needle tip and a thread guide groove on one side and on one edge of the the looper side opposite the thread guide groove has a chamfer.
  • the needle modules have a contact surface which is provided with a projecting strip can be.
  • the bar can be designed as a molding, which in a groove of the needle bar intervenes. It can also be designed as an abutment bar that is attached to the the needle bar rests on the lower edge.
  • German utility model 295 06 819.1 shows a needle module with two contact surfaces and molded onto both contact surfaces, which in a groove of the needle bar intervention.
  • the module can thus also be rotated by 180 ° Position can be used.
  • the number of tools required can be done this way be halved.
  • the needle module When the needle module is in operation, it penetrates after piercing a basic tissue on one side of a tufting needle a looper between the side surface of the needle and the Thread and hold the thread. This way, when moving up again the needles formed loops.
  • the needles on this side surface at a certain angle to the direction of movement Chamfered looper.
  • the invention has for its object in the system of tufting needles and needle modules to provide further simplifications so that the needle modules for all constellations of looper versions can be used.
  • the object is achieved in that on the second edge of the looper side a chamfer is also provided.
  • the tufting needle can guide the thread guide groove and the looper side in the middle dividing plane be formed symmetrically.
  • a needle module 1 shows a needle module 1, consisting of a base body 2 and the tufting needles 3, which are molded into the base body 2 with part of their piston 4.
  • the base body 2 is provided with a bore 5 on a needle bar.
  • the shaft 7 of the tufting needles 3 has a thread guide groove 8 for thread guidance, as is clear in the view of FIG. 3. From the perspective of Fig. 2 is the Thread guide groove 8 is located on the back of the needles 3. At the tip of the needles 3 there is an eye 9 through which the thread is passed.
  • the needle module 1 can be used for tufting machines, which are not here Looper shown, based on a position of the needle module, as shown in Fig. 2, moving from a direction from the left towards the needle module 1 and past the needles on the right be or from a direction from the right to the needle module 1 and left to the Needles over.
  • the loopers tap between the left of them upward moving needles and threads and in the other case between the right of the needles and the threads moving them up and down.
  • FIGS. 4 to 6 show a needle module 1 with needles 3, as are previously known.
  • the needles 3 are provided with a chamfer 10 on only one edge. They are therefore only suitable for tufting machines, the looper from the view of FIG. 4 from the left on the needle module to be moved and grab the thread to the right of the needles.
  • the needle module 1 When the needle module 1 is rotated by 180 °, the needle module 1 is suitable for tufting machines, their looper, analogous to the view in FIG. 5, but now with one rotated by 180 ° Needle module, is moved from the right to the needle module and the thread to the right of grab the needles.
  • a needle module would be necessary, the needles of which are on the opposite edge are chamfered.
  • a needle module equipped with the needles according to the invention can, if it is also is designed so that it can also be used in a position rotated by 180 ° for all variants of tufting machines are used.

Abstract

L'invention concerne un type d'aiguilles de tufting qui sont moulées en grand nombre en modules à aiguilles, montés à leur tour sur une barre d'aiguilles. Sur une face, ces aiguilles de tufting présentent un canal guide-fil, ainsi qu'un biseau sur un bord du côté boucleur opposé audit canal guide-fil. Selon l'utilisation voulue et le type de boucleur, différentes variantes doivent être mises à disposition. L'invention vise par conséquent à simplifier davantage le système d'aiguilles de tufting et de modules à aiguilles, de manière que les modules à aiguilles puissent s'utiliser pour tous les types de boucleurs. Selon l'invention, il est également prévu un biseau sur le deuxième bord du côté boucleur de l'aiguille de tufting.
