 .;#';# L'invention cet relative dispositif servant à diviser ##une feuille en matière synthétique en bandes étroites. i1e tels disposi- ..titr pauea étre utilisés par exemple, pour réaliser des !fil* déplia 'dei ieuiJ 148 en matière synthétiques ..

   ' V Lorsque les feuilles en matière synthétique sont dirigées par.=.nombre de couteaux disposée les une l c6t des autres et en ti- ..reat les fouillée au moyen d'une paire de cylindres entre cette rangée 
 EMI1.3 
 de couteaux il est fréquent que la bande en matière synthétique dévie légèrement dans la zone située devant Ion couteaux et tome de légères ondulations  

 <Desc/Clms Page number 2> 

 De ce fait la division en bandes peut être rendue plue   difficile.   



   L'invention   vise   à éliminer   ces     difficultés.   



     Conformément   à l'invention, ceci   cet   obtenu du faitque devant les oouteaux   (vu   dans le sens de   l'avancement   de la   feuille)   cet également prévue une paire de cylindrée qui acheminent la feuille, tandis que la paire de cylindrée située derrière les couteaux et qui tire donc la feuille entre la rangée de oouteaux, présente une vites- se périphérique qui est légèrement plue élevée, par exemple de quel- quee pourcents, que celle de l'autre paire de cylindrée.

   Cette dis- position   cet   particulièrement avantageuse lorsqu'il   s'agit   de disposi- titi dans lesquels la feuille en matière synthétique est divisée par un nombre de couteaux circulaires fixes et dans lesquels la feuille est tirée entre ces couteaux et une bas. fixe. 



   Une forme d'exécution, donnée à titre d'exemple non limita- tif, est représenté* au dessin annexé. 



   Une feuille 1 en matière synthétique, par exemple une feuil- le en polyéthylène ayant une épaisseur de 0,04 mm, est déroulée depuis un rouleau 2 au moyen d'une paire de cylindrée 3, 4 à une vitesse de 4 m/minute ;la vitesse périphérique de ces deux   cylindrée   étant éga- lement de 4 m/minute. Derrière la paire de cylindrée 3, 4 est prévu un nombre de couteaux circulaires 5 qui   cent   fixée sur un axe non- rotatif 6 de manière à ne pas tourner, Sous la rangée de   couteaux 5   est prévue une base fixe 7.

   La base 7   cet   constituée, par exemple, par une plaque métallique 7a sur la surface plane de laquelle est fixée, par exemple collée, une couche de matière élastique 7b, par exemple en caoutchouc et présentant, par exemple, une épaisseur d'un millimètre, tandis que sur la oouohe 7b est   collée   une mince feuille métallique 7c. La   base 7   est pressée au moyen de   ressort.   contre les couteaux 5. 



   La feuille1 en matière synthétique est divisée en   bandes   1a, b,   etc...   entre les couteaux 5 et la base 7 prenait depuis le bas contre ces derniers. Une paire de cylindres   8,   9 achemine les bandes a une vitesse de 4,12    /minute    La vitesse périphérique des   cylindres   8, 9   est   donc de 3 pourcents supérieure à   celle   des cylin- dres 3,4. Le diamètre des cylindres 3,   4,   8, 9 peut être compris, par exemple, entre 50 et 200 mm.

  On * pu constater avec surprise que grâce à ce dispositif   Simple,   on obtient avec certitude une orientation absolument uniforme   et' lisse   de la feuille 1 dans la   sone   qui précède immédiatement les   'couteaux 5   et   quoi   de cette manière, il était également   possible   de
