   PROCEDE DE RENFORCEMENT DU CARTON ONDULE. 



   La présente invention a pour objet un procédé de renforcement du carton ondulé utilisé pour la confection des emballages. 



   Après que la feuille de carton a été ondulée par des cylindres   calendreurs   une feuille de recouvrement est collée de part et d'autre de ce cartono Ces feuilles de recouvrement peuvent se déchirer au cours de la fabrication du carton, de la confection ou de l'emploi de l'emballage; le carton ondulé lui-même peut se déchirer dans le sens parallèle aux cannelures et les ondulations peuvent avoir tendance à s'ouvrir sous la pression de la matière emballée, avec comme conséquence une diminution de la rigidité de l'emballageo
La présente invention a pour objet de remédier à ces inconvénients en augmentant la résistance à la déformation des ondulations et en faisant obstacle à la propagation de déchirures amorcées dans le carton d'emballage, sans augmenter sensiblement le poids au mètre carré du carton. 



   Elle se caractérise par   l'intercalation,   entre le carton ondulé proprement dit et les feuilles de recouvrement, de fils textiles de haute ténacité fixés par collage, et solidarisant entre elles les crêtes des ondulations du cartono
Un exemple fera mieux comprendre la portée de l'invention:

  
Si on confectionne une boîte de la manière habituelle à l'aide   d'un   carton ondulé recouvert de feuilles collées sur les ondulations, toute déchirure d'une des feuilles de recouvrement ou du carton lui-même se propagera aisément sur toute la longueur de la face entaméeo En,cas de charge un peu forte, les feuilles de papier auront tendance à céder, les ondulations du carton pourront s'ouvrir et la rigidité de la boîte sera diminuéeo   Si,   suivant   l'invention    des fils textiles de haute ténacité ont été intercalés en travers des cannelures entre les feuilles de recouvrement et le carton ondulé,et adhèrent par collage aux sommets des ondula-   tions,   toute amorce de déchirure sera limitée par la rencontre du premier

   PROCESS FOR REINFORCING THE CORRUGATED BOARD.



   The present invention relates to a method for reinforcing corrugated cardboard used for making packaging.



   After the cardboard sheet has been corrugated by calendering cylinders a cover sheet is glued on either side of this cardboard.These cover sheets can tear during the manufacture of the cardboard, the confection or the packaging. use of packaging; the corrugated cardboard itself may tear in the direction parallel to the grooves and the corrugations may tend to open under the pressure of the packed material, resulting in a decrease in the rigidity of the packaging.
The object of the present invention is to remedy these drawbacks by increasing the resistance to deformation of the corrugations and by preventing the propagation of tears initiated in the packaging cardboard, without significantly increasing the weight per square meter of the cardboard.



   It is characterized by the intercalation, between the corrugated cardboard proper and the covering sheets, of high tenacity textile threads fixed by gluing, and joining together the crests of the corrugations of the cardboard.
An example will better understand the scope of the invention:

  
If a box is made in the usual way using corrugated cardboard covered with sheets glued to the corrugations, any tear in one of the cover sheets or in the cardboard itself will easily propagate along the entire length of the box. face started o If, in the event of a slightly heavy load, the sheets of paper will tend to give way, the corrugations of the cardboard can open and the rigidity of the box will be reduced o If, according to the invention, high tenacity textile yarns have been interposed across the grooves between the cover sheets and the corrugated cardboard, and adhere by gluing to the tops of the corrugations, any initiation of tearing will be limited by the meeting of the first
