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.
