Abstract:
A multi-component fiberizing disk for fiberizing a molten fiberizable material in a rotary fiberization process comprising:an outer annular sidewall component having fiberizing holes therein through which a molten fiberizable material passes to fiberize the fiberizable material;an upper annular flange component having an outer annular peripheral edge portion;a disk shaped base component having an upper surface for receiving and delivering molten fiberizable material to the outer annular sidewall for fiberization; the disk shaped base component having an outer annular peripheral edge portion;the outer annular sidewall component extending generally perpendicular to the upper annular flange component and the disk shaped base component and from the outer annular peripheral edge portion of the upper annular flange component to the outer annular peripheral edge portion of the disk shaped base component; at least two of the outer annular sidewall, the upper annular flange and the disk shaped base components being separable from each other and held together by fastening means to form a fiberizing disk; andthe fastening means securing the separable components together as the fiberizing disk and permitting the separable components to be disassembled after service; the fastening means being a plurality of removable fasteners that extend between and secure together the upper annular flange component and the disk shaped base component; and each of the fasteners being enclosed within sleeve means passing from an under surface of the upper annular flange component to the upper surface of the disk shaped base component to prevent the molten fiberizable material being fiberized from hardening about the fastener when the fiberizing disk is taken out of service thereby enabling the fastener to be easily removed from the fiberizing disk for disassembly.
