An apparatus is provided for making dual component fibers. The apparatus comprises a distributor, equipment for providing first and second thermoplastic materials to the distributor, a rotatable spinner and a rotation mechanism. The distributor has an outer casing and a divider cup fixedly positioned within the outer casing. The outer casing has first and second orifices extending through its peripheral wall. The divider cup defines with the outer casing first and second chambers for receiving first and second molten thermoplastic materials. The first orifices communicate with the first chamber and the second orifices communicate with the second chamber. The rotatable spinner includes first and second passages in its peripheral wall. The rotation mechanism rotates the distributor and the spinner to centrifuge layers of the first and second thermoplastic materials through the first and second orifices and to centrifuge dual component fibers through the first and second passages in the peripheral wall of the spinner. |
