<p>In the manufacture of a pencil for cosmetic use, the pencil core or stick (4) is obtained by injecting a melted cosmetic mixture into a stiffening tube (5) of plastic material which, after being optionally closed at the ends, is fitted between the two half cases (2a, 2b) of wood forming the external body (2) of said pencil (1). By the use of said stiffening tube (5) an automatic handling of the cores (4) is allowed even when the mixture injected into the tube, once cooling has occurred, still exhibits a high malleability. <IMAGE></p> |
