Description

  

  Filtre pour article<B>à</B> fumer et procédé pour la confection d'un tel filtre    La plupart des filtres connus dont sont munis les  cigares ou les cigarettes sont faits au moyen     d!une     bande d'un matériau plissé longitudinalement, cette  bande     passa-nt    dans un entonnoir collecteur servant  <B>à</B> la comprimer pour en faire un cylindre qui sera  ensuite gainé et découpé<B>à</B> la longueur voulue. Du  fait du plissement longitudinal du matériau les cons  tituant, ces filtres ne retiennent pas plus<B>de 10 à</B>  <B><I>15</I> %</B> des goudrons.  



  Les     fig.   <B>1</B> et<B>3</B> représentent respectivement la  bande de matériau et le dispositif pour comprimer  cette bande.  



  Dans<B>le</B> but de remédier<B>à</B> ces inconvénients, la  présente invention a pour objet un filtre pour arti  cles<B>à</B> fumer, caractérisé par le fait que le matériau  <B>le</B> composant est torsadé.  



       Uinvention    a également pour objet un procédé  pour la confection d'un tel filtre, caractérisé par le  fait que la bande du matériau destinée,<B>à</B> former le  filtre subit une torsion au voisinage d'un entonnoir  collecteur de ce matériau d'une machine<B>à</B> fabriquer  les filtres.  



  Le dessin annexé représente, aux     fig.    2 et 4,<B>à</B>  titre d'exemple, une forme d'exécution de l'objet de  l'invention.  



  La     fig.    2 est une vue schématique d'une baguette  servant<B>à</B> la confection de filtres selon l'invention.  La     fig.    4 est une vue schématique d'un disposi  tif servant<B>à</B> la confection<B>de</B> la baguette de la     fig.    2.  Les     fig.   <B>1</B> et 2 permettent de comparer une ba  guette servant<B>à</B> former des filtres usuels dont le     ma-          téri,au    présente des plis longitudinaux et une ba  guette servant<B>à</B> former des filtres selon l'invention,  dans lesquels<B>le</B> matériau est torsadé. L'expérience a  démontré qu'un tel filtre offrait une rétention aux  goudrons nettement supérieure<B>à</B> celle d'un filtre  usuel.

      Pour     conféotionner    un filtre dont le matériau est  torsadé, on fait usage d'une machine<B>à</B> fabriquer les  filtres pourvue d'un entonnoir collecteur<B>1</B>     (fig.    4).  Une bande de matériau 2 provenant d'un rouleau  non représenté et présentant des plis longitudinaux<B>3</B>  passe<B>à</B> travers une fente<B>7</B>     dun    disque<B>6</B> placé entre  le     rouleauct    l'entonnoir. En faisant tourner le disque  <B>6</B> sur son axe, on provoque la torsion de la bande  de matériau 2 qu'on tire simultanément hors de l'en  tonnoir<B>1</B> dans le sens de la flèche<B>8.</B> Le matériau 2  se présente alors sous la forme d'une baguette torsa  dée<B>9.</B>  



  <B>Il</B> est prévu -de placer le disque<B>6</B> avant l'entrée  de l'entonnoir<B>1,</B> ou<B>à</B> l'intérieur dudit entonnoir.  Le disque<B>6</B> peut être animé     d#un    mouvement  rotatif alternatif ou continu<B>;</B> dans ce cas, il<B>y</B> a éga  lement lieu de faire tourner simultanément le rouleau  de matériau, afin d'éviter la -torsion dudit matériau  entre<B>le</B> rouleau et le disque.  



  On pourrait également torsader le matériau 2 en  effectuant la torsion<B>à</B> la sortie<B>de</B> l'entonnoir.



  Filter for smoking articles and method for making such a filter Most of the known filters with which cigars or cigarettes are fitted are made by means of a strip of material pleated longitudinally, this band passes through a collecting funnel serving <B> to </B> compress it into a cylinder which will then be sheathed and cut <B> to </B> the desired length. Due to the longitudinal wrinkling of the material constituting them, these filters do not retain more than <B> from 10 to </B> <B> <I> 15 </I>% </B> of the tars.



  Figs. <B> 1 </B> and <B> 3 </B> respectively represent the strip of material and the device for compressing this strip.



  With <B> the </B> aim of remedying <B> to </B> these drawbacks, the present invention relates to a filter for <B> </B> smoking articles, characterized in that the <B> the </B> component material is twisted.



       The invention also relates to a process for making such a filter, characterized in that the strip of material intended to <B> to </B> form the filter is subjected to a twist in the vicinity of a collecting funnel of this material of a <B> </B> filter making machine.



  The accompanying drawing represents, in FIGS. 2 and 4, <B> to </B> by way of example, one embodiment of the object of the invention.



  Fig. 2 is a schematic view of a rod serving <B> for </B> the making of filters according to the invention. Fig. 4 is a schematic view of a device serving <B> for </B> the preparation <B> of </B> the rod of FIG. 2. Figs. <B> 1 </B> and 2 make it possible to compare a bay window serving <B> to </B> form usual filters, the material of which has longitudinal folds and a bay window serving <B> to < / B> forming filters according to the invention, in which <B> the </B> material is twisted. Experience has shown that such a filter offers significantly greater tar retention <B> than </B> that of a conventional filter.

      To make a filter of which the material is twisted, use is made of a <B> </B> machine making the filters provided with a collecting funnel <B> 1 </B> (fig. 4). A strip of material 2 coming from a roll not shown and having longitudinal folds <B> 3 </B> passes <B> through </B> through a slot <B> 7 </B> of a disc <B> 6 </B> placed between the roller and the funnel. By rotating the disc <B> 6 </B> on its axis, it causes the torsion of the material strip 2 which is simultaneously pulled out of the funnel <B> 1 </B> in the direction of the arrow <B> 8. </B> Material 2 is then in the form of a twisted rod <B> 9. </B>



  <B> It </B> is planned -to place disk <B> 6 </B> before the entry of funnel <B> 1, </B> or <B> to </B> l 'inside said funnel. The disc <B> 6 </B> can be driven with an alternating or continuous rotary motion <B>; </B> in this case, it is also <B> </B> necessary to rotate simultaneously the roll of material, in order to avoid the -torsion of said material between <B> the </B> roll and the disc.



  We could also twist the material 2 by performing the twist <B> at </B> the outlet <B> of </B> the funnel.
