[origin: EP0277619A2] The present invention is a spinneret (3) for making hollow fibers from polymeric spinning solutions and/or melts. The spinneret is characterized in that it comprises a pin mounting means (13) for detachably securing a core fluid pin (15). The detachable pin mounting design allows for the manufacture of hollow fibers having different wall thicknesses by simply changing the core fluid pins.
