Abstract

Dans ce procédé de gainage d'un crayon, on introduit le crayon dans un tube d'un diamètre légèrement supérieur à celui du crayon et réalisé en une matière plastique thermorétractable. Puis on chauf­ fe l'ensemble tube-crayons de manière à provoquer la rétraction de la matière plastique et son application contre la surface externe dudit crayon. In this pencil sheathing process, the pencil is introduced into a tube with a diameter slightly higher than that of the pencil and produced in a heat-shrinkable plastic. Then we heat fe the tube-pencil assembly so as to cause the plastic shrinkage and its application against the outer surface of said pencil.
