Definitions

  • the invention relates to a module with tufting tools, in particular needles, in which the tufting tools are cast into a base body, the length of which corresponds to a multiple of the center distance of the cast-in tufting tools, which on its rear side, which can be connected to a bar, with a contact strip and recesses and on its front side is provided with a receiving shoulder and projections and has an elongated hole running in the longitudinal direction of the module and going from the back to the front.
  • Such a module for a tufting machine is known from DE-PS 2 828 278.
  • the modules can be screwed onto a needle bar.
  • Each base body has on its rear side facing the needle bar two conical recesses which are spaced apart in the longitudinal direction of the module.
  • two projections which are also at a distance, are provided on the front of the base body. The recesses and the projections are dimensioned such that the projections of one module can engage in the recesses of another if the two modules joined together are offset by half a needle pitch.
  • the object of the present invention is now to avoid this disadvantage of the known module.
  • it is to be achieved without reducing the number of required basic bodies to be designed differently without sacrificing the precision of the modules to be joined together.
  • the recessed row of teeth allows the rear of the module to be easily attached to a bar, e.g. Needle bar, too.
  • the teeth of the rack on the front of one module can be easily inserted into the spaces between the teeth of another module. This results in automatic alignment in the longitudinal direction. It is possible to move the connection between two modules that interlock in this way by one or more additional teeth. As a result, the relative position of the tufting tools of adjacent rows can be changed in two or more stages.
  • the module according to the invention can also be designed such that the center distance of the tufting tools is n times the distance between the teeth, where n is an integer> 1.
  • the module according to the invention can also be designed such that the spaces between the row of teeth are offset with respect to the teeth of the rack, this offset 1 / n of the center distance between the tufting tools and n being an integer> 1.
  • the module according to the invention can also be designed such that the row of teeth of the contact strip and the toothed strip of the receiving shoulder is adjacent.
  • the system bar and the mounting shoulder serve to simplify the alignment of the modules on the bar or on the neighboring module row.
  • the module according to the invention can be designed such that the tooth flanks of each tooth form an angle with one another of 35 ° to 50 °.
  • the tooth flanks of each tooth form an angle with one another of 35 ° to 50 °.
  • the module shown in the figures has a base body 1, in which the pistons are cast by tufting needles 2 arranged in parallel and equidistantly.
  • the base body 1 has a rear side 3 and a front side 4 running parallel thereto. From the back 3, a system bar 5 projects. This contact strip 5 is adjacent to a row of teeth 6 sunk in the rear 3.
  • a receiving shoulder 7 is provided on the front 4 at the level of the contact bar 5. This is one from the Front 4 protruding rack 8 adjacent.
  • An elongated hole 9 is also provided in the base body, which extends through the base body 1 and has its longer axis in the longitudinal direction of the module.
  • the diameter of the elongated hole 9 widens from the front 4 towards the rear for demolding reasons
  • the sunk row 6 has equidistant teeth 10 with straight flanks.
  • the profile of the teeth 10 corresponds to the profile of the spaces 11 between the teeth 10.
  • the toothed rack 8 on the front side 4 has teeth 12 and spaces 13 which correspond in their profile to that of the row of teeth 6.
  • one tooth 12 of the toothed strip 8 lies opposite an intermediate space 11 of the row of teeth 6.
  • the teeth 12 of the toothed strip 8 can consequently be inserted into the intermediate spaces 11 of the toothed row 6 of a further module of the same design, the front side 4 then on the Back 3 comes to rest.
  • Two modules joined together in this way can be joined together in a plurality of positions displaced relative to one another in the longitudinal direction of the module.
  • FIGS. 5-8 show two modules joined together in this way.
  • the contact strip 5 of one module lies on the receiving shoulder 7 of the other module, while the toothed strip 8 of the one engages in the tooth row 6 of the other.
  • the elongated holes 9 are not completely aligned with one another, but each elongated hole projects above the other in the longitudinal direction. Both slots of the stacked modules leave a common passage through which a screw, not shown, can be passed to fix the modules on the bar.
  • the module can be used to form a row of needles, by placing two rows of modules together to form two rows of needles, and also to form three or four rows of needles. Only the length of the elongated holes 9 is to be selected in accordance with the maximum offset of the two modules lying on one another.

Abstract

Un module avec des instruments de tufting, en particulier des aiguilles, où les instruments de tufting (2) sont coulés dans un corps de base (1), dont la longueur correspond à un multiple de la distance moyenne entre les instruments de tufting (2) qui y sont insérés, est doté en sa face arrière (3), qui peut se fixer sur une barre, d'un rebord de fixation (5) et d'évidements et, sur sa face avant (4), d'un épaulement de logement (7) et de parties saillantes. Ce module est traversé sur sa longueur par un orifice allongé (9) allant de sa face arrière (3) à sa face avant (4). Les évidements de la face arrière (3) sont formés par les interstices d'une série de dents (6), ces dents (10), agencées en retrait, étant identiques et équidistantes entre elles et présentant des flancs droits. Les parties saillantes de la face avant sont formées par un rebord de dents (8) saillantes, les dents (12) et les interstices (13) du rebord de dents (8) correspondant aux interstices (11) et aux dents (10) de la rangée de dents en retrait (6).
