Extrusion coating apparatus

摘要

The present invention relates to an extrusion coating apparatus having a structure which is capable of correctly forming and applying a coating layer with a desirable cross-sectional form even when thermal distortion occurs in its extrusion unit. This extrusion coating apparatus comprises an extrusion unit extruding a thermoplastic resin while heating the resin, a coating unit providing a coating layer of the thermoplastic resin from the extrusion unit around a linear body pulled at a predetermined tension, and various distortion-absorbing structures absorbing the distortion in the extrusion unit caused by heating the thermoplastic resin.
