<p>The present invention relates to an extrusion die for coating a coating material on an outer circumference surface of yarn which is continuously transferred. The extrusion die comprises: an internal die integrally having a coating pipe in which a through-hole is formed at the center to transfer the yarn, and a finishing plate in which a supply hole is formed to supply the coating material inside on an outer surface in the middle of the coating pipe; an external die forming a screw hole interlocked with one end of the coating pipe and inducing detachment and attachment, and a space in which the coating material is supplied by being interlocked with the finishing plate; and a coating unit forming a coating hole which brings the coating material supplied to the space into the through-hole on the coating pipe, and a coating section which is integrally coated as the brought coating material is united with the yarn. Accordingly, as the coating section integrally coated as the coating material and the yarn are united is formed in the internal die, overall quality of coating yarn is improved, and manpower and costs occupied in manufacture can be reduced.</p> |
