ECRITEAU EN MATIERE PLASTIQUE
Comme on le sait, la matiere plastique présente les mames inconvénients que le verre quand il s'agit d'y inscrire des caracteres, cela surtout à causa de sa surface polie et non poreuse,la présente invention a pour but de remédier à ces inconvénients.
Le procédé consiste à dépolir'la face ou les faces du moule servant à la production des objets destinés à recevoir des inscriptions telles que étiquettes pour étalages, ardoises d'écoliers etc @
Ce dépolissage s'obtient tres facilement par jet de, sable sur le métal du moule à l'endroit désiré 1
<Desc/Clms Page number 2>
Les pièces produites dans un tel moule présentent une.
surface légèrement rugueuse permettant une inscription facile
EMI2.1
k la craie ou à la touche décoliertees-inscrîptions peuvent s'effacer aussi facilement que sur les matières employées précédemment pour ce genre d'écriture
La matière plastique destnée à cet usage sera naturelle- -ment de couleur foncée
Le dessin annexé présente une étiquette à surface rugueuse,11 doit etre entendu que l'invention n'est nullement - limitée a ce genre d'objet 1

PLASTIC MATERIAL
As we know, plastic has the same drawbacks as glass when it comes to inscribing characters, especially because of its polished and non-porous surface, the present invention aims to remedy these drawbacks. .
The process consists in roughening the face or faces of the mold used for the production of objects intended to receive inscriptions such as labels for displays, school slates etc @
This roughening is very easily obtained by sandblasting the metal of the mold at the desired location 1
<Desc / Clms Page number 2>
The parts produced in such a mold have a.
slightly rough surface for easy registration
EMI2.1
k chalk or with the touch of decoliertees-inscriptions can be erased as easily as on the materials previously used for this kind of writing
The plastic material intended for this use will naturally be dark in color.
The accompanying drawing shows a label with a rough surface, 11 should be understood that the invention is by no means limited to this kind of object 1
