Description

  

  <B>Fil métallique ondulé et procédé pour sa</B>     fabrication.       La     présente    invention a pour objet un fil  métallique du     genre    de ceux destinés à rece  voir un plomb de     scellement    que l'on emploie  pour     sceller    des     colis,    des     appareils,    etc.  



  Ces fils doivent présenter une surface of  frant une bonne prise au plomb qui, sur un  fil lisse,     glisserait    et n'offrirait     aucune    sécu  rité. On utilisait     jusqu'à        présent    à cet effet  du fil dit      perlé ,    constitué par une âme en  fil rond sur laquelle     est        enroulé    en hélice à       pas    serré un second fil dont les spires forment       les    perles ou sinuosités du fil perlé.

       Celui-          ci    a     toutefois        l'inconvénient    d'être coûteux en       raison    du faible rendement des     machines    en  rouleuses     servant    à sa fabrication.  



       L'invention    a pour objet     un    fil ondulé,  dont la     section        transversale        est    de forme géné  rale     rectangulaire,    caractérisé en ce qu'il est:  ondulé dans le plan contenant le grand axe  de     sa    section     transversale.    On appelle plan  d'ondulation le plan contenant l'axe longitu  dinal du fil qui a été ondulé.

   La     fabrication     d'un     tel    fil     est    notablement plus rapide et  moins coûteuse que celle du fil perlé, dont il  constitue cependant un excellent élément de       substitution.    Ce fil convient aussi remarqua  blement bien à la confection d'éponges métal  liques et     d'ustensiles    ménagers     analogues.     



  Le fil ondulé suivant l'invention s'obtient  en ondulant préalablement un fil     lisse    et en  laminant     ensuite    ce fil ondulé pour fixer     ses          ondulations,    les     axes    des cylindres du lami  noir     étant        parallèles    au plan dans     lequel    se    développent les ondulations.

   Contrairement à  un fil simplement ondulé, qui redevient     lisse          soins    l'effet d'une traction, le fil laminé con  serve     ses        ondulations.        Aussi        convient-il    par  faitement au but     proposé.     



  Le dessin annexé représente, à titre d'exem  ple, une forme d'exécution de l'objet de l'in  vention.  



  La     fig.    1 montre, à     grande        échelle,        un    fil  perlé.  



  La     fig.    2     représente        un    fil ondulé, et  la     fig.    3 montre     un    fil plat ondulé, ob  tenu par laminage du fil ondulé.  



       Fig.    4 et 5 montrent schématiquement des  dispositifs     employés    pour onduler et     laminer     le fil.  



  Le fil perlé     représenté    à la     fig.    1 est du  type usuel comprenant une âme 1 en fil     lisse     sur     laquelle    est     enroulé    en     spires        hélicoïdales     un second fil     lisse    2. On conçoit que l'enroule  ment de ce dernier mer l'âme constitue     canne     opération lente, ne pouvant être exécutée       qu'avec        un        médiocre    rendement de la ma  chine     utilisée    à cet effet.  



  lia     fig.    2 montre un fil 3, par exemple  rond, qui est ondulé. Un tel fil ne convien  drait pas pour retenir un plomb, car ses     ondiz-          lations        cèderaient    à la traction et le plomb       glisserait    sur le fil redevenu     lisse.     



  Tout autre     est    le comportement du fil plat  ondulé 4, représenté à la fis. 3, qui est obtenu  par laminage du fil rond     ondulé    de la fis. 2,  les axes des cylindres du laminoir étant pa-           rallèles    au plan dans lequel se développent  les ondulations, fixées par le     laminage,    les       ondulations    du fil plat résistent à la trac  tion     sans    subir de     déformation    sensible, rete  nant avec     sécurité        im    plomb fixé sur ce fil,  tout comme le fil perlé de la     fig.    1.  



  Les     ondulations    5 du fil plat peuvent  avoir toute     conformation    voulue,     résultant    de       celles    données au fil ondulé dont elles     pro-          viennent.     



       Un.    moyen simple d'onduler le fil     con-          este    à le faire passer entre deux galets den  tés. 6, 7,     comme    le montre la     fig.    4. On peut  aussi enrouler le Men     boudin    sur une broche  et     l'étendre    ensuite pour     former    les ondula  tions, .ou encore employer tout autre moyen  approprié.  



  Le     fil    ondulé 3     (fig.    5)     est        passé    entre les  cylindres de     laminage    8, 9, les :axes de ces    derniers étant parallèles au plan dans lequel  se développent les ondulations du fil. On ob  tient     ainsi    un     fil    de section droite     rectang@u-          laire    et ondulé 4. Ce fil ondulé     convient        aussi     à la     fabrication    d'éponges et tampons métal  liques destinés au     neUoyage.  



  <B> Corrugated metal wire and process for its </B> manufacture. The present invention relates to a metal wire of the type of those intended to receive a sealing lead which is used to seal packages, apparatus, etc.



  These wires must have a surface offering a good lead grip which, on a smooth wire, would slip and offer no safety. Until now, so-called beaded wire has been used for this purpose, consisting of a core of round wire on which is wound in a tight-pitch helix a second wire, the turns of which form the beads or sinuosities of the beaded wire.

       However, this has the drawback of being expensive because of the low efficiency of the rolling machines used in its manufacture.



       The subject of the invention is a corrugated wire, the cross section of which is generally rectangular in shape, characterized in that it is: corrugated in the plane containing the major axis of its cross section. The plane containing the longitudinal axis of the wire which has been corrugated is called the wavy plane.

   The manufacture of such a thread is notably faster and less expensive than that of pearl thread, for which it nevertheless constitutes an excellent replacement element. This yarn is also remarkably well suited for making metal sponges and similar household utensils.



  The corrugated wire according to the invention is obtained by corrugating a smooth wire beforehand and then rolling this corrugated wire to fix its corrugations, the axes of the cylinders of the black laminate being parallel to the plane in which the corrugations develop.

   Unlike a simply corrugated yarn, which becomes smooth again after pulling, the rolled yarn retains its undulations. So it is perfectly suited to the proposed purpose.



  The appended drawing represents, by way of example, an embodiment of the object of the invention.



  Fig. 1 shows, on a large scale, a pearl thread.



  Fig. 2 shows a wavy wire, and FIG. 3 shows a corrugated flat wire obtained by rolling the corrugated wire.



       Fig. 4 and 5 schematically show devices employed for corrugating and rolling the wire.



  The pearl thread shown in fig. 1 is of the usual type comprising a core 1 of smooth wire on which is wound in helical turns a second smooth wire 2. It is understood that the winding of the latter mer the soul constitutes a slow operation cane, which can only be carried out. with a mediocre performance of the ma chine used for this purpose.



  lia fig. 2 shows a wire 3, for example round, which is wavy. Such a wire would not be suitable for retaining a lead, because its corrugations would give way to traction and the lead would slide on the wire which had become smooth again.



  Quite different is the behavior of the wavy flat wire 4, shown at fis. 3, which is obtained by rolling the round corrugated wire of the yarn. 2, the axes of the rolls of the rolling mill being parallel to the plane in which the corrugations develop, fixed by the rolling, the corrugations of the flat wire resist the traction without undergoing appreciable deformation, retaining with security im lead fixed on this thread, like the pearl thread of fig. 1.



  The corrugations of the flat yarn can have any desired conformation resulting from those given to the corrugated yarn from which they originate.



       A simple way of waving the yarn is to pass it between two toothed rollers. 6, 7, as shown in fig. 4. You can also wind the Men sausage on a spit and then extend it to form the waves, or use any other suitable means.



  The corrugated wire 3 (FIG. 5) is passed between the rolling rolls 8, 9, the axes of the latter being parallel to the plane in which the undulations of the wire develop. This gives a wire of rectangular cross section and corrugated 4. This corrugated wire is also suitable for the manufacture of sponges and metal buffers intended for cleaning.
