Abstract

Instruments de dessin tels que règles, équerres, pistolets, etc.. en matière plastique moulée. L'une au moins, référencée 3, de ses faces est rendue rugueuse de façon à ne pas renvoyer la lumière incidente dans les veux de l'utilisateur. C'est la surface du moule utilisé pour la fabrication en matière plastique qui est rendue rugueuse. Matériel pour bureaux de dessin.Drawing instruments such as rulers, squares, guns, etc. made of molded plastic. At least one, referenced 3, of its faces is roughened so as not to reflect the incident light in the wishes of the user. It is the surface of the mold used for plastic manufacturing which is roughened. Equipment for design offices.
