Comme le montrent les figures 2 à 5, l'élément de ,{  <EMI ID=22.1> 

  
Chacun des espaces creux précités 13 est circulaire lorsque l'arête 11 et la cannelure 12 ont chacune une forme

  
 <EMI ID=23.1> 

  
ment de fixation A de la présente invention comporte des  arêtes et des cannelures sur ses deux faces. De plus, dans  <EMI ID=24.1> 

  
arêtes et les cannelures sont disposées en quinconce suivant uns relation mutuelle fixe. En ce qui concerne une bande

  
 <EMI ID=25.1> 

  
dans chaque intervalle entre des cannelures 12. En outre,  ,dans le groupe de bandes ondulées disposées méthodiquement  en parallèle, chaque 'bande individuelle est réunie à sa 

  
 <EMI ID=26.1> 

  
lesdits points étant disposés en ligne droite-dans le sens . 

  
de la largeur de l'élément de fixation" -En conséquence,  l'élément de fixation peut être plié le long de ces pointa  d'assemblage sans déformer les arêtes et les cannelures, de  sorte que l'élément de fixation possède une flexibilité  suffisante. 

  
Lorsqu'on plie un élément de fixation sous forme  d'une bande sans fin pour pouvoir tourner ses faces opposées 

  
 <EMI ID=27.1> 

  
le montrent les figures 6 et 7, de façon que les cannelures

 <EMI ID=34.1>   <EMI ID=35.1>

Etant donné que la distance comprise entre des  adjacentes dans urne 'bande ondulée donnée peut

 <EMI ID=39.1> 

  
une saillie 14 sous forme d'un grain de part et d'autre de  chaque arête et/ou cannelure de la 'bande ondulée. Du point  de vue pratique, étant donné que l'élément de fixation est

En ce qui concerne la position des saillies 14, il

les arêtes du presser élément de fixation sont placées de façon à reposer sur les cannelures du second élément comme le Eontre la. figure 9. Tenu le cas de la figure 10 dans

  
 <EMI ID=49.1> 

  
de part et d'autre de la base des cannelures.

  
les saillies précitées 14 pèsent avoir la forme

 <EMI ID=51.1>  Après leur passage, les cornes ou crochets 15 reprennent

  
 <EMI ID=52.1> 

  
tique tandis qu'ils viennent s'accrocher par derrière sur les arêtes de l'autre élément de fixation, formant ainsi

  
 <EMI ID=53.1> 

  
!sa. figure 13 illustre un élément de fixation comportant des bandes formées uniquement par une répétition

  
 <EMI ID=54.1> 

  
arêtes (ou des cannelures) courbes 21 ayant la même forme et disposées d'une manière continue. Lesdites 'bandes ondulées réalisées en matière plastique sont disposées l'une par rapport à l'autre de telle sorte que les sommets des arêtes d'une 'bande soient alignés avec les points de fonction des arêtes de l'autre bande.

  
En conséquence, l'élément de fixation réalisé de la

  
 <EMI ID=55.1> 

  
dire sa face ou son dos par suite de la présence du groupe

  
de bandes ondulées, tandis qu'il comporte des cavités 22 épousant la forme desdites arêtes prévues sur l'autre face.

  
En prévoyant, sur une face d'un ruban, des arêtes disposées en alignement avec des cavités 22 pratiquées dans l'autre face dé l'autre ruban, on peut obtenir une fermeture par le  même principe que celui de 1.' élément de fixation des figures 

  
 <EMI ID=56.1> 

  
 <EMI ID=57.1>  

  
 <EMI ID=58.1> 

  
fabrication plus aisée.

  
Les éléments, de fixation des formes de réalisation illustrées dama les figures 15 à. 24 comportent plusieurs  bandes ondulées d'une largeur fixe a qui sont réunies 1.'une  <EMI ID=59.1> 

  
lèle à l'extrémité inférieure des arêtes et à l'extrémité ' des parties planes.

  
Toutefois, lorsque la longueur des parties planes

  
 <EMI ID=60.1>   <EMI ID=61.1> 

  
former les arêtes. Dans l'un ou 1* autre case vu dans la :  sens de l'épaisseur perpendiculairement à la. direction des  bandes ondulées, le plan constitué des parties planes forme

  
 <EMI ID=62.1> 

  
de réalisation précitée comporte des arêtes faisant saillie sur la surface frontale avec un groupe de 'bandes ondulées 

  
 <EMI ID=63.1> 

  
planes de cette dernière ou en des pointa situés légèrement  <EMI ID=64.1>  pénètrent dans les espaces creux formés par les arêtes 31'

  
 <EMI ID=65.1> 

  
 <EMI ID=66.1>  <EMI ID=67.1>  <EMI ID=68.1> 

  
 <EMI ID=69.1> 

  
élément de fixation en appliquant la face dorsale du premier sur la face frontale du second, de façon à. pouvoir superposer n'importe quel nombre d'éléments de fixation en une série. 

  
On peut également plier un élément de fixation sous forme d'un ba.nde sans fin et engager mutuellement ses, deux extrémités

  
en plaçant leurs faces opposées l'une contre l'autre, formant ainsi une 'boucle.

  
L'élément de fixation de la construction décrite ci-dessus est fermé par la force d'engagement exercée sur

  
les 'borda latéraux des arêtes ou sur les parties planes d'un autre élément de fixation. Lorsqu'on utilise deux éléments 

  
 <EMI ID=70.1> 

  
s'avère insuffisante pour obtenir la fermeture désirée,

  
on surmonte cette difficulté en utilisant un élément de fixation modifié suivant la forme de réalisation illustrée dans 

  
 <EMI ID=71.1> 

  
de chaque arête . Lors de la fermeture, les saillies sont 

  
comprimées lorsqu'elles passent par les espaces ménagés  <EMI ID=72.1> 

  
dernier. Apres le passage des arêtes, elles reprennent leur forme initiale.. 

  
Des lors, les saillies 34 servent à presser vers le'bas les arêtes sur la face supérieure des parties planes . sur lesquelles sont passées ces arêtes. Les saillies appliquent ainsi, en plus de la force de contact et de friction, une force permettant de maintenir l'élément de fixation dans la position de fermeture. Dès lors, pour ouvrir l'élément-de fixation, il faut une importante force qui doit non seulement surmonter 2a force de contact et de friction, mais également déformer par compression le groupe

  
 <EMI ID=73.1> 

  
L'élément de fixation destiné a être serré sur

  
 <EMI ID=74.1> 

  
 <EMI ID=75.1> 

  
ment de fixation dépourvu desdites saillies. 

  
Les saillies 34 peuvent être en forme de crochets inclinés vers les parties planes 32 comme le montre la figura

  
 <EMI ID=76.1>  fabrication d'un élément de fixation du type précité en se

  
 <EMI ID=77.1>  semblés latéralement face à face, ainsi que deux rouleaux  supports 46 assemblée chacun au disque extérieur 44 de ladite  section de formation d'élément de fixatifs 45* Entre les deux rouleaux supports 46, est disposé un arbre support 47 destiné

  
 <EMI ID=78.1> 

  
immobilisés ensemble en une série.- Chaque disque. 44 a la 

  
 <EMI ID=79.1> 

  
circonférence ondulée 48. 

  
Ladite circonférence ondulée 48 a la même forme 

  
 <EMI ID=80.1> 

  
Chaque paire de disques adjacents sont disposés l'un par  rapport à l'autre de telle sorte que les arêtes (cannelures)  d'un disque s'étendent à proximité immédiate des cannelures 
(arêtes de l'autre disque. 

  
Etant donné que les deux disques adjacents de chaque  pairesont disposés de telle sorte que le sommet des arêtes

  
 <EMI ID=81.1> 

  
adjacent, les ondulation de chacun des autres - disques sont parfaitement alignées.

  
 <EMI ID=82.1> 

  
disques -utilisés dans ce rouleau.- 

  
Les rouleaux-de la construction précitée sont disposés l'un derrière l'autre à de courts intervalles pour constituer le groupe de rouleaux 43.

  
Ledit rouleau est opposé, en travers d'un petit

  
 <EMI ID=83.1> 

  
dans les cannelures (arêtes) des ondulations au second rouleau. Lorsque la feuille souple sortant du dispositif  d'extrusion 41 est dirigée dans l'espace libre :ménagé entre

  
 <EMI ID=84.1> 

  
feuille. Après le passage de la feuilla dans les espaces ménagés entre les différentes paires de rouleaux opposés" lesdites 'bandes d'ondulations sont stabilisées en donnant,

  
à un ruban d'élément de fixation, une forme défini tire suite

  
à la déperdition progressive de chaleur. Ledit ruban d'élé-  ment de fixation est alors amené dans l'espace ménagé entre  un rouleau de garniture de carde 49 dans la surface duquel des picots sont implantés d'une manière dense, et un rouleau presseur 50 maintenu légèrement en contact avec ledit rouleau
49, tandis qu'il en est déchargé de telle sorte que les ondu-

  
 <EMI ID=85.1> 

  
description donnée à ce propos couvre uniquement un élément  de fixation dont la fermeture est assurée par la force de  contact et de friction entre des arêtes et des cannelures.

  
 <EMI ID=86.1> 

  
 <EMI ID=87.1> 

  
pratiquées latéralement au sommet des arêtes dans les ondula-  tions de chaque disque 44 constituant un rouleau 42. Lors-  qu'on fait passer une feuille souple dans une série de ces  rouleaux, des saillies de base 15' sont formées sur le plan 

  
 <EMI ID=88.1> 

  
cannelures 12 de chaque bande d'ondulations comme le montre  la figure 30. 

  
Dans ce cas, si l'on élargit légèrement l'espace  en travers duquel les paires de rouleaux sont opposés, les  'bandes ondulées formées sur la feuille sous la pression exer- 

  
 <EMI ID=89.1>

Hence, the protrusions 34 serve to press down the ridges on the upper face of the planar parts. over which these edges have passed. The protrusions thus apply, in addition to the contact and frictional force, a force to keep the fastener in the closed position. Therefore, to open the fastener requires a large force which must not only overcome the contact and friction force, but also compress the group.
