Abstract

Machine pour l'extrusion de matières plastiques, qui, au moyen d'une pièce conformatrice comportant une série de canaux triangulaires divergents, permet la formation d'une bande unique de plusieurs couleurs juxtaposées, solidaire par sa partie inférieure formée d'une couche blanche de support et par sa partie supérieure formée d'une couche uniforme plastique transparente; cette machine permet donc la formation de ces bandes de longueur variable, de différentes couleurs, présentant un dégré de finition très élevé; ces bandes de diverses couleurs sont utilisées pour de multiples usages commerciaux.Machine for the extrusion of plastics, which, by means of a shaping part comprising a series of divergent triangular channels, allows the formation of a single strip of several juxtaposed colors, integral by its lower part formed by a white layer support and by its upper part formed by a uniform transparent plastic layer; this machine therefore allows the formation of these bands of variable length, of different colors, having a very high degree of finish; these bands of various colors are used for multiple commercial uses.
