Definitions

  • the invention relates to a tufting needle, consisting of a piston which can be at least partially molded into a needle module, and a shaft which has a needle tip provided with an eye and a thread guide groove on one side and a chamfer on one edge of the looper side opposite the thread guide groove having.
  • a large number of such tufting needles are molded into needle modules, which in turn are attached to a needle bar.
  • the needle modules have a contact surface which can be provided with a projecting strip.
  • the bar can be designed as a molding bar which engages in a groove of the needle bar. It can also be designed as a contact strip which bears against the lower edge of the needle bar when it is fastened.
  • a needle module is already known from WO 95/23 253, the two sides of which are designed as contact surfaces. Accordingly, a contact strip is formed on both contact surfaces.
  • German utility model 295 06 819.1 shows a needle module with likewise two contact surfaces and molded strips on both contact surfaces, which engage in a groove in the needle bar.
  • the module can thus also be used in a position rotated by 180 °.
  • the number of tools required can be halved in this way. This has the following technical background:
  • the needles on this side surface are chamfered at a certain angle to the direction of movement of the looper.
  • the number of variants required can be halved, since one module can be twisted for both loops arranged on the left and right of the needle bar. This leaves two variants for looper engaging on the left or right side surfaces of the needles.
  • the invention has for its object to provide further simplifications in the system of tufting needles and needle modules, so that the needle modules can be used for all constellations of looper designs.
  • the object is achieved in that a chamfer is likewise provided on the second edge of the looper side.
  • the tufting needle can be designed symmetrically with respect to a plane dividing the thread guide groove and the looper side in the middle.
  • FIG. 2 shows a needle module corresponding to FIG. 1 in side view
  • FIG. 3 is an enlarged view of a module with the tufting needles according to the invention from below,
  • FIG. 4 shows the side view of a needle module with previously known tufting needles
  • Fig. 5 is an enlarged view of the needle module corresponding to FIG. 4 in the view from below.
  • 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 for attachment to a needle bar.
  • a contact strip 6 is formed on both sides of the base body 2. With one of the contact strips 6, the needle module 1 then bears against the lower edge of a needle bar during operation of a tufting machine.
  • the shaft 7 of the tufting needles 3 has a thread guide groove 8 for thread guidance, as is clear in the view according to FIG. 3. From the view of FIG. 2, 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, the looper of which is not shown here to a position of the needle module as shown in FIG. 2, from a direction from the left towards the needle module 1 and to the right past the needles or from a direction from the right towards the needle module 1 and past the needles.
  • the looper intervenes between the needles and the threads moving up and down to the left, and in the other case between the needles and the threads moving up and down to the right.
  • the needle module 1 When the needle module 1 rotates on the needle bar, the needle module is suitable for tufting machines whose loopers are moved from the left towards the needle bar and to the left past the needles or from the right towards the needle bar and right past the needles.
  • 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 of which, in the view of FIG. 4, are moved towards the needle module from the left and grip the thread on 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, the looper of which, analogous to the view in FIG. 5, but now with a needle module rotated by 180 °, is moved from the right toward the needle module and the Grab the thread to the right of the needles.
  • a needle module For tufting machines, whose looper grips the thread to the left of the needles, viewed from the direction of movement of the looper, a needle module would be necessary, the needles of which are chamfered on the opposite edge.
  • a needle module equipped with the needles according to the invention can, provided that it is also designed in such a way that it can also be used in a position rotated by 180 °, can be used for all variants of tufting machines.

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.
