Spinner for manufacturing dual-component fibers

Apparatus for making dual glass fibers comprising:

• a) a spinner having a peripheral wall with an internal surface and an external surface and a bottom wall, and further including orifices located in said peripheral wall for centrifuging dual component fibers, said spinner being divided into a series of compartments by baffles positioned interiorly of said peripheral wall;
• b) equipment for supplying first and second molten glasses to said spinner;
• c) a first divider for directing said first molten glass against said peripheral wall and into alternate ones of said compartments and a second divider for directing said second molten glass against said peripheral wall and into remaining ones of said compartments;
• and
• d) a plurality of passage pairs extending through said peripheral wall wherein each, of said passage pairs includes first and second passages which are angled relative to one another to communicate with one another and with a selected one of said orifices, said first passage communicates with a first compartment so as to permit flow of said first molten glass to said selected orifice and said second passage communicates with a compartment so as to permit flow of a second molten glass to said selected orifice.

• c) a first divider for directing said first molten glass into alternate ones of said compartments, said first divider including a first generally horizontal plate positioned along the tops of said baffles and abutting said peripheral wall of said spinner, said first plate including a series of first orifices therein spaced to provide access for said first molten glass to flow into said alternate ones of said compartments;
• and a second divider for directing said second molten glass into remaining ones of said compartments, said second divider including a second generally horizontal plate positioned along the bottoms of said baffles and abutting said peripheral wall of said spinner, said second plate including a series of second orifices therein spaced to provide access for said second molten glass to flow into said remaining ones of said compartments;
• and
• d) passages extending through said peripheral wall and communicating with said compartments and said orifices in said peripheral wall through which said molten glasses flow to said orifices in said peripheral wall of said spinner.
