   PROCEDE DE FABRICATION DE   PLAQUES,   BANDES OU TUBES EN MATIERES PLASTIQUES 
PRODUISANT DIVERS EFFETS OPTIQUES. 



   On a déjà fabriqué' des feuilles, plaques ou tubes de couleur en matières plastiques d'apparence transparente ou opaque en mélangeant des co- lorants aux mélanges de matières premières servant à leur fabrication ou en traitant les produits finis en appliquant ces colorants au pinceau, par im- mersion au par projectiono 
Ces deux   p rocédés   ont de graves inconvénientso Si la coloration s'effectue dans la masse, on est obligé d'avoir à sa disposition un équipé- ment spécial pour chaque teinte, etco ou bien on est obligé de nettoyer l'é- quipement après chaque nouvelle opérationo Aucun de ces procédés n'est éco- nomiqueo 
L'application au pinceau, l'immersion et la projection donnant lieu à toute une série de difficultés,

   dont la plus grande consiste dans   l'obtention   d'une régularité suffisante de la couche de couleur sur des sur- faces étendues 
En outre les objets colorés superficiellement sont très sensi- bles aux actions mécaniques et chimiques. 



   Un procédé de fabrication connu depuis longtemps de feuilles, plaques et bandes d'épaisseur supérieure à 0,1 mm et de tubes consiste à as- sembler sous forme définitive plusieurs couches ou enroulements de feuilles plus minces à l'aide de solvants ou de matières adhésives en faisant inter- venir éventuellement la chaleur et la pression.

   Cette opération peut s'effec- tuer lorsqu'il s'agit de bandes de feuilles et de plaques avec des calandres ou machines analogues et lorsqu'il s'agit de tubes sur des machines à en- rouler les douilleso 
Or il a été découvert qu'il est possible aussi de fabriquer des plaques, bandes ou tubes en matières plastiques produisant des effets opti- ques divers d'une manière extrêmement simple en ajoutant les colorants, pig- ments, bronzes métalliques et/ou autres éléments en poudre ou en paillettes 

 <Desc/Clms Page number 2> 

 non aux masses plastiques, mais aux solvants ou matières adhésives qui ser- vent à assembler les diverses couches. 



   Les avantages particuliers de ce procédé sont les suivants: 
Il permet de fabriquer les objets ainsi obtenus par la main- d'oeuvre la plus modeste sans dépense d'équipement supplémentaire. 



   La couche productrice d'effets optiques se trouve entre les di- verses couches de l'objet fini et par suite est complètement protégée con- tres les détériorations. La couche de couverture transparente rend les cou- leurs encore plus éclatantes. 



   Le procédé permet aussi de choisir des colorants solubles dans la feuille de support mais solubles seulement dans le solvant ou matière ad- hésive. 



   Il est possible suivant l'invention d'obtenir dans des feuilles, bandes, plaques ou tubes se composant de plusieurs couches des effets dont le nombre est illimité en choisissant pour les diverses couches des feuilles, plaques ou bandes de surface brillante ou mate, estampée ou modifiée d'une manière quelconque. On peut aussi assembler par exemple deux feuilles au moyen d'un solvant transparent coloré en rouge, assembler la double feuille rouge ainsi obtenue avec une feuille opaque blanche au moyen d'une colle dans laquelle les pigments ou le bronze métallique sont irrégulièrement ré- partis. On peut encore ajouter au solvant ou à la colle des éléments soli- des de forme et dimensions les plus diverses, mais de diverses transparen - ces et/ou divers indices de réfraction par rapport au matériau qui consti- tue les feuilles ainsi que par rapport à la colle.

   On peut aussi introduire entre les feuilles du papier ou du tissu en même temps que les additions aux solvants. 



   On constate avec surprise qu'on obtient suivant   l'invention   des objets dont la stabilité est satisfaisante et dont les effets optiques sont extrêmement réguliers.

   PROCESS FOR MANUFACTURING PLATES, STRIPS OR TUBES IN PLASTICS
PRODUCING VARIOUS OPTICAL EFFECTS.



   Colored sheets, plates or tubes of transparent or opaque appearance have already been manufactured by mixing dyes with mixtures of raw materials used in their manufacture or by treating the finished products by applying these dyes with a brush, by immersion at by projectiono
These two processes have serious drawbacks o If the coloring is carried out in the mass, we are obliged to have at our disposal special equipment for each shade, etc. or else we are obliged to clean the equipment after each new operationo None of these processes is economicalo
Application with a brush, immersion and projection giving rise to a whole series of difficulties,

   the greatest of which consists in obtaining a sufficient evenness of the color layer over extensive surfaces
In addition, superficially colored objects are very sensitive to mechanical and chemical actions.



   A long-known manufacturing process for sheets, plates and strips with a thickness greater than 0.1 mm and of tubes consists in assembling in final form several layers or windings of thinner sheets using solvents or materials. adhesive, possibly involving heat and pressure.

   This operation can be carried out in the case of webs of sheets and plates with calenders or similar machines and in the case of tubes on case-winding machines.
Now, it has been discovered that it is also possible to manufacture plastic plates, bands or tubes producing various optical effects in an extremely simple manner by adding dyes, pigments, metallic bronzes and / or the like. powder or glitter elements

 <Desc / Clms Page number 2>

 not to plastic masses, but to solvents or adhesive materials which serve to assemble the various layers.



   The particular advantages of this process are as follows:
It makes it possible to manufacture the objects thus obtained by the most modest manpower without the expenditure of additional equipment.



   The optical effects producing layer is between the various layers of the finished article and is therefore completely protected against damage. The transparent cover layer makes the colors even more vibrant.



   The method also allows the selection of colorants soluble in the carrier sheet but soluble only in the solvent or adhesive material.



   It is possible according to the invention to obtain in sheets, strips, plates or tubes consisting of several layers of effects of which the number is unlimited by choosing for the various layers sheets, plates or strips of glossy or matt surface, stamped or modified in any way. One can also assemble for example two sheets by means of a transparent solvent colored in red, assemble the double red sheet thus obtained with a white opaque sheet by means of an adhesive in which the pigments or the metallic bronze are irregularly distributed. . It is also possible to add to the solvent or to the glue solid elements of the most diverse shapes and sizes, but of various transparencies and / or various refractive indices with respect to the material which constitutes the sheets as well as with respect to the film. with glue.

   Paper or fabric can also be introduced between the sheets at the same time as the solvent additions.



   It is surprisingly found that, according to the invention, objects are obtained whose stability is satisfactory and whose optical effects are extremely regular.
