PROBLEM TO BE SOLVED: To provide a technique for preventing a resin passing through the inside of a resin flow path from contamination due to foreign matters.SOLUTION: A resin coating apparatus 1 is equipped with a head flange 3 in which at least a part of a resin flow path 4 extruding a resin into a crosshead 2 coating the resin on the circumference of a core wire 100 to flow the resin on the circumference of the wire 100 is formed. The head flange 3 is equipped with a thin wall part 5 deforming in response to the pressure of the resin flowing in the resin flow path 4, and a gauge 6 measuring the flexure amount of the thin wall part. The inner peripheral face of the thin wall part 5 has a continuous smooth surface having no irregularity and is formed so that the resin does not stay.SELECTED DRAWING: Figure 1 |
