Claims

[Scope of utility model registration request]

A first cylinder having a spherical surface formed on its front end surface, and a nipple inserted into the first cylinder with a swingable clearance, holding a nipple at its tip and formed on the front end surface of the first cylinder. and a second cylinder having a spherical surface that engages with the spherical surface and a hollow hole for guiding the conductor therein, the nipple in the inner layer being rocked by the rocking means without rocking the second cylinder, In a crosshead for multi-layer coating of electric wires in which resin flow channels of other layers are formed on the outer peripheral surfaces of the nipple holder and the nipple, respectively, the first cylinder of the inner layer forming the resin flow channels and the entire circumference of the tip of the nipple holder of the other layer are provided. A protrusion is provided adjacent to the groove for resin inflow, and the length of the protrusion is the longest at a position corresponding to the resin inflow port mounting position and the shortest at a position 180 degrees away. Improved crosshead for multi-layer coating of electric wires.
