Abstract

La invencion se relaciona con un procedimiento de fabricacion continuo de lapices para escribir o colorear, el cual consiste de: coextruir un primer material termoplastico cargado, denominado material de la mina, y alrededor de este, una capa intermedia, llamada capa de proteccion en un material termoplastico exento de agente de expansion, y un segundo material termoplastico que contiene un agente de expansion, denominado material similar a la madera, y de enfriar dichos materiales termoplasticos coextruidos. La invencion se caracteriza porque el material termoplastico que constituye la capa de proteccion es seleccionado de manera que permanezca deformable durante la retraccion del material de la mina, durante el proceso de enfriamiento. El lapiz (1) esta formado por la superposicion de un nucleo (1) de un primer material termoplastico cargado, denominado material de la mina, de una capa de proteccion de un material termoplastico no expandido (2) y de una capa (3) de un segundo material termoplastico expandido, denominado material similar a la madera. La invencion esta caracterizada porque el material termoplastico que forma la capa de proteccion (2), tiene un punto de solidificacion menor que aquel del material termoplastico que forma el material de la mina (1).
