Definitions

  • the innovation relates to a module for tufting tools, in particular needles, in which the tufting tools are cast at one end in a plate-shaped base body, the length of which corresponds to a multiple of the center distance of the cast-in tufting tools, which has a front and a rear contact surface, the The front contact surface is provided with a projecting contact strip on its longitudinally extending edge in the region of the exit of the tufting tools from the base body, and which has a continuous opening between the front and the rear contact surface.
  • Such a module for a tufting machine is known from EP 0 446 215.
  • the base body has on its front side a contact strip, which comes into contact with a needle bar or a part thereof in the assembled state and enables an exact alignment of the module with respect to the needle bar.
  • This needle module can therefore only be fixed in one orientation on the needle bar.
  • the tufting tools accommodated in such a module can consequently only be used in a single rotary setting for the bar. If it is therefore necessary to use the tufting tools in a different rotary setting with respect to the bar, which is changed by 180 °, it is necessary to use modules in which the rotary setting of the needles is changed accordingly. Two types of modules must then be kept ready, in which the tufting tools deviate from one another in their rotational position by 180 °. This requires various modules to be kept available and is consequently expensive.
  • Each base body is provided with an opening in the form of a through hole through which a screw to attach the module to the bar or the like can be passed.
  • the insertion and removal of such a module requires that the screw is first completely removed from the hole for this purpose.
  • the task on which the innovation is based is, in particular, to create a module which can be installed and removed easily and quickly with a simple construction.
  • this object is achieved in a module of the type mentioned at the outset in that the opening is formed by at least one cutout starting from the upper edge of the base body.
  • the new module can be designed so that the cutout has the shape of an elongated hole open at one end.
  • the module according to the innovation can also be designed such that the cutout is continuously open to a side edge of the base body. In this case, a cutout that is open toward the side edge is then expediently provided on both side edges of the base body. These cutouts can accommodate a screw to fix the module. When two modules lying next to one another interact, the cutouts can have the shape of an elongated hole through which a screw can be passed, in order in this way to fix two modules in the region of one side edge. Each module is expediently locked in the same way on both side edges.
  • the module according to the invention can also be designed such that it has at least two rows of tufting tools arranged in parallel, the tools of one row being offset from those of the adjacent row. In this way, finer divisions can be achieved in the tufting process.
  • the new module can also be designed so that the tufting tools of the different rows are arranged in a common one-piece base body.
  • the module according to the innovation can also be designed such that the tufting tools are arranged in sections which form a base body and are detachably connected to one another.
  • the module according to the innovation can be designed such that the base body is also provided with a contact strip on its rear contact surface.
  • This training can make it possible to use the tufing tools cast in the module optionally in two positions rotated 180 ° relative to one another. This means that the number of tools required can be halved compared to the practice previously required for this.
  • FIG. 1 is a view of the front contact surface of a module according to the innovation, which is equipped with tufting needles,
  • FIG. 2 is a side view of the module of FIG. 1,
  • FIG. 3 shows a view of the front contact surface of a further module according to the invention with two rows of tufting tools
  • 4 shows a side view of the module according to FIG. 3
  • FIGS. 3 and 4 show a plan view of the module according to FIGS. 3 and 4,
  • FIG. 6 is a view of the front contact surface of a further module according to the invention with two rows of tufting tools and two elongated holes,
  • FIG. 7 is a side view of the module of FIG. 6,
  • FIGS. 6 and 7 are plan views of the module of FIGS. 6 and 7,
  • FIG. 9 is a view of the front contact surface of a further module according to the innovation, each with a cutout on the two side edges,
  • FIGS. 9 and 10 shows a side view of the module according to FIGS. 9 and
  • FIG. 11 shows a plan view of the module according to FIGS. 9 and 10.
  • the module shown in FIGS. 1 and 2 has a base body 1 with a front contact surface 2 and a rear contact surface 3 running parallel thereto.
  • the pistons of tufting needles 4 are cast into the base body 1.
  • the base body 1 is formed symmetrically with respect to a plane of symmetry 5 running centrally between the front contact surface 2 and the rear contact surface 3. In the area in which the tufting needles 4 emerge from the base body 1, it has one contact strip 6, 7 projecting over the two contact surfaces 2, 3. These contact strips 6, 7 each have a stop shoulder 8 which, in the assembled state, is struck against a needle bar or parts thereof and thus align the module with respect to the needle bar. tet.
  • the axes of the tufting needles 4 lie parallel to one another in the plane of symmetry 5 of the base body 1.
  • the base body 1 is provided with an elongated hole 9 which extends normally to the contact strips 6, 7. It is open at the edge 10 of the base body 1 opposite the contact strips 6, 7.
  • the elongated hole 9 extends from the front contact surface 2 to the rear contact surface 4.
  • the base body 1 and thus the entire module can thus be placed in the area of the elongated hole 9 on the shaft of a screw or the like. be postponed or withdrawn from it.
  • this module can be fixed in two rotational positions on a bar, the rotational position of the needles being changed accordingly.
  • the embodiment of the module according to the invention described in FIGS. 3 to 5 has two parallel rows of tufting needles 4, which are offset by half a pitch.
  • the module has a base body 11 with a front contact surface 12, a rear body surface 13, an upper edge 14 and a lower edge 15.
  • a contact strip 16 is provided which is in contact with the front contact surface 12 forms a shoulder 17.
  • the base bodies 11 formed in this way can be arranged side by side in any number, the needle spacing in each row remaining the same across the dividing line between adjacent modules.
  • the base body 11 forms a shoulder 23 in its upper, rear region 22, which can be used as a stop surface.
  • the module according to the embodiment according to FIGS. 6 to 8 differs from the embodiment according to FIGS. 3 to 5 only in that here two parallel elongated holes 25 are provided in a base body 24 which are open towards the upper edge 14.
  • FIGS. 9 to 11 differs from the embodiments previously described with reference to FIGS. 3 to 8 only in that a base body 26 is provided here, which is open from its upper edge 14 and is continuously open to the side edges 27 Cutouts 28 has. If modules according to this embodiment are now lined up, the cutouts 28 of adjacent modules then complement one another to form an elongated hole. A screw passed through such an elongated hole then acts simultaneously on the two abutting modules. In this case, each module is expediently held on its two side edges by a screw, this screw in turn acting simultaneously on two adjacent modules.

Abstract

L'invention concerne un module comportant des outils de tufting, notamment des aiguilles (4), dans lequel les outils de tufting sont scellés à une de leurs extrémités dans un corps de base (1) se présentant sous forme de plaque. La longueur du corps de base (1) correspond à un multiple de la distance centre à centre séparant les outils de tufting scellés. Le corps de base (1) comporte au moins une perforation se présentant sous forme de trou oblong (9) perpendiculaire à la /aux barre(s) d'appui et ouverte au niveau du bord (14) supérieur du corps de base (1). Ce dernier (1) peut être symétrique et comporter une barre d'appui (6, 7) tant au niveau de sa surface d'appui avant qu'à celui de sa surface d'appui arrière (2, 3). Cette barre d'appui (6, 7) sert à placer avec précision le module sur une platine. Le module, et par conséquent les outils de tufting qui y sont scellés, peuvent de ce fait s'utiliser dans deux différentes positions de rotation.
