Abstract:
An extrusion coating apparatus comprising:an extrusion unit for extruding a thermoplastic resin while heating said resin; a coating unit provided at a predetermined position so that a linear body pulled at a predetermined tension penetrates therethrough, thereby applying a coating layer of said thermoplastic resin around said linear body; a connecting tube having a first opening connected to a resin inlet of said coating unit, and a second opening opposing said first opening and being connected to a resin-extruding orifice of said extrusion unit; and a distortion-absorbing structure for absorbing a distortion in said extrusion unit caused by heating said thermoplastic resin, said distortion-absorbing structure including a structure for making said extrusion unit movable with respect to said coating unit, wherein said distortion-absorbing structure includes a structure for making said extrusion unit movable with respect to said coating unit, wherein said extrusion unit is provided such that an angle formed between a pass-line direction of said linear body and an extruded direction of said heated thermoplastic resin is not less than 0Â° but less than 90Â°, and wherein said connecting tube has such a form that is bent at a predetermined portion thereof from said first opening toward said second opening.
