ABSTRACT:
An apparatus for manufacturing a resin cord with enclosed fine metal wires is provided as a unit, in which fine metal wires are supplied from a nipple to a die while extruding a resin around the nipple into the die for burying the fine metal wires in the resin in the length direction of a hollow or solid resin cord, the nipple having a central space in its section perpendicular to the extruding direction and also fine metal wire supply grooves joining the central space, a nozzle made of a wear-resistant material being provided in the central space. The outer diameter of the cord is 0.3 to 2.0 mm, the thickness of the resin part is 0.1 mm or above, the diameter of fine metal wires is 0.03 to 0.2 mm, and the thickness of the resin part is greater than the diameter of the fine metal wires.
