ABSTRACT:
An extrusion die for adhering a tape on a rubber article which is extruded is composed of a die base fixed to an outlet port of an extrusion head to form a nozzle for allowing the article to extrude, a tape supply member connected with the die base which is oriented at adjacent a first surface of the article to partially supply the tape toward the first surface for allowing to mate the both so as to form a lamination, and a pressurizing member movably connected with the die base oriented at adjacent a second surface of the article to pressurize the article toward the tape for adhering the both. The pressurizing member is slidably reciprocated with respect to the direction of the article extruded to keep a distance from the article when the tape is not supplied thereto.
