Abstract

Mejoras introducidas en moldes para la fabricación de cubiertas de neumáticos que se utilizan para aplicar un diseño de banda de rodamiento a la superficie de una cubierta mientras se vulcaniza la cubierta, teniendo dichos moldes de cubierta unos respiraderos destinados a dar paso al aire que quedaría aprisionado cuando se introduce caucho no vulcanizado en la sección de dibujo de banda de rodamiento del molde, caracterizadas porque consisten por lo menos en un clavo que tiene un vástago introducido en un respiradero de molde, teniendo el clavo una cabeza, estando la cabeza situada en el interior de la cavidad del molde, y atravesando el vástago del clavo del respiradero, estando cada clavo sujeto en su sitio de modo que cada vástago pueda desplazarse a lo largo de respiradero con un recorrido variable entre 0 y 0,125 mm.
