Abstract

Method of attaching by crimping sheets of paper, especially a sheet of paper folded on itself, characterised in that it consists of producing on each edge two series of parallel tongues which interpenetrate in respect of thickness and are offset relative to each other so as jointly to provide an approximately continuous crimping, with the edges of these tongues, parallel to the edges of the sheets, resulting from a clean cut, whereas their end results from a tearing of the paper.

Description

Parmi les procédés de scellement pour billets destinés aux jeux de hasard, le plus simple consiste à glisser une feuille dans une enveloppe fermée par collage. Toutefois, ce procédé est relativement onéreux car il nécessite l'utilisation d'une  Among the sealing methods for tickets intended for games of chance, the simplest consists in sliding a sheet in an envelope closed by gluing. However, this process is relatively expensive because it requires the use of a

O On connaît aussi un procédé de scellement d'une feuille de papier repliée sur elle-même consistant à délimiter en bordure d'une feuille de papier, au moyen d'une perforation périphérique, une zone de collage permettant de sceller la feuille repliée sur elle-même. Pour ouvrir la feuille, il suffit de déchirer les bords scellés le long de la ligne de perforation. Ce procédé présente également l'inconvénient d'être relativement coûteux car il nécessite l'encollage du bord de la  O There is also known a method of sealing a sheet of paper folded over on itself consisting of delimiting at the edge of a sheet of paper, by means of a peripheral perforation, a bonding zone allowing the sheet folded to be sealed on herself. To open the sheet, simply tear the sealed edges along the perforation line. This method also has the disadvantage of being relatively expensive since it requires the gluing of the edge of the

La présente invention a pour but de proposer un procédé :0 d'assemblage peu onéreux qui permet d'obtenir un scellement  The object of the present invention is to propose a method: inexpensive assembly which makes it possible to obtain a seal.

Le procédé d'assemblage selon l'invention consiste à réaliser sur les bords d'une feuille de papier préalablement repliée sur elle-même deux séries de languettes parallèles s'interpénétrant en épaisseur et décalées l'une par rapport à l'autre de manière à créer ensemble un scellement approximative  even. The assembly method according to the invention consists in producing on the edges of a sheet of paper previously folded back on itself two series of parallel tabs which interpenetrate in thickness and offset one with respect to the other so to create an approximate seal together

L'interpénétration en épaisseur des languettes résulte en IO une solidarisation efficace et irréversible des épaisseurs de la  The interpenetration in thickness of the tabs results in IO an effective and irreversible joining of the thicknesses of the

feuille de papier.sheet of paper.

Cette solidarisation s'obtient, conformément à l'invention, au moyen de languettes dont les bords parallèles à ceux de la feuille résultent d'une coupe franche, mais dont l'extrémité résulte d'un arrachage du papier. Ces languettes sont réalisées, conformément à l'invention, au moyen de dents de perforation de forme prismatique usinées sur une roue, à raison de deux couronnes de perforation par roue, ces couronnes de perforation coopérant avec un contre-outil constitué T de trois disques parallèles séparés par deux entretoises et dont  This joining is obtained, according to the invention, by means of tongues whose edges parallel to those of the sheet result from a straight cut, but whose end results from tearing off the paper. These tongues are produced, in accordance with the invention, by means of prismatic perforation teeth machined on a wheel, at the rate of two perforation rings per wheel, these perforation rings cooperating with a counter-tool made up of three discs parallel separated by two spacers and of which

l'écartement est égal à la largeur des dents de perforation.  the spacing is equal to the width of the perforation teeth.

Le dispositif permettant la mise en oeuvre du procédé selon l'invention se caractérise essentiellement en ce qu'il comprend deux jeux de roues mobiles en rotation, chaque roue comportant deux couronnes de perforation munies de dents de perforation présentant approximativement la forme d'un prisme à base triangulaire, les dents de perforation étant inclinées par rapport aux rayons de la roue dans le sens de rotation de cette dernière et opérant entre trois disques parallèles portés par une roue servant de contre-outil et séparés l'un de l'autre par un  The device allowing the implementation of the method according to the invention is essentially characterized in that it comprises two sets of wheels movable in rotation, each wheel comprising two perforation rings provided with perforation teeth having approximately the shape of a prism with a triangular base, the perforation teeth being inclined relative to the spokes of the wheel in the direction of rotation of the latter and operating between three parallel discs carried by a wheel serving as a counter-tool and separated from each other by a

espace égal à la largeur des dents de perforation.  space equal to the width of the perforation teeth.

En raison de la forme des dents de perforation et de la disposition du contre-outils, les épaisseurs de papier insér'ées entre ce dernier et les roues portant les couronnes de perforation sont découpées en forme de languettes dont les bords parallèles à ceux de la feuille, résultent d'une coupe franche mais dont  Due to the shape of the perforation teeth and the arrangement of the counter-tools, the thicknesses of paper inserted between the latter and the wheels carrying the perforation crowns are cut in the form of tongues whose edges parallel to those of the leaf, result from a clean cut but whose

l'extrémité résulte d'un arrachage du papier.  the end results from tearing off the paper.

En effet, les dents de perforation coopérant avec les disques servant de contre-outil réalisent des coupes franches latérales mais effectuent entre les disques, et en raison de l'absence à cet endroit de contre- surface de coupe, un arrachage du papier sur une longueur correspondant à la longueur de  Indeed, the perforation teeth cooperating with the discs serving as a counter-tool make lateral clear cuts but perform between the discs, and due to the absence at this location of counter cutting surface, tearing off the paper on a length corresponding to the length of

l'extrémité des dents de perforation.  the tip of the puncture teeth.

L'invention sera mieux comprise à la lecture de la  The invention will be better understood on reading the

Sur la figure unique du dessin annexé, on voit la roue 1 mobile en rotation portant deux couronnes de perforation 2 et 3 munies chacune de dents de perforation identiques 4 et 4', les  In the single figure of the appended drawing, we see the wheel 1 movable in rotation carrying two perforation rings 2 and 3 each provided with identical perforation teeth 4 and 4 ', the

Ces découpes franches sont suivies d'un arrachage du papier dû au fait que les extrémités des dents 4 et 4' opèrent  These straight cuts are followed by a tearing off of the paper due to the fact that the ends of the teeth 4 and 4 'operate

sans contre-outil, mais à l'intérieur d'un espace vide.  without a tool, but inside an empty space.

Les languettes ainsi formées s'interpénètrent en épaisseur, et ce d'autant plus efficacement que l'extrémité de chaque languette ne résulte pas d'une découpe franche: on peut en effet admettre que la formation par arrachage des extrémités des languettes provoque une interpénétration en épaisseur des fibres de papier résultant en une solidarisation particulièrement efficace. L'ouverture de la feuille scellée ainsi obtenue provoque une désolidarisation par arrachage des languettes qui 'rend  The tongues thus formed interpenetrate in thickness, and this all the more effectively since the end of each tongue does not result from a sharp cut: it can indeed be admitted that the formation by tearing off the ends of the tongues causes interpenetration in thickness of the paper fibers resulting in a particularly effective joining. The opening of the sealed sheet thus obtained causes separation by tearing off the tabs which 'makes
