ABSTRACT:
A fiber manufacturing apparatus including a spinner, mounted on one end of a rotatable shaft, and a source supplying two streams of at least one molten thermoplastic material to the spinner. The spinner includes a radial extension, a radial wall, and an outer peripheral wall. The radial extension is mounted to and extends radially out from the shaft. The radial wall is mounted to and extends radially out from the radial extension. The radial wall includes an upper surface, a lower surface, and an outer periphery. The peripheral wall is disposed around the outer periphery of the radial wall and has a plurality of orifices for centrifuging fibers from at least one molten thermoplastic material. During the operation of the spinner, the radial extension directs one stream of molten thermoplastic material through at least one flow hole to the lower surface of the radial wall and to orifices of the peripheral wall. As the spinner rotates, another stream of molten thermoplastic material is deposited directly onto the upper surface of the radial wall and travels along the upper surface to orifices of the peripheral wall. The spinner is radially balanced during the centrifuging operation and is less susceptible to thermal stress induced cracking.
