Abstract
An insulating flow block having a plurality of bores extending therethrough to permit the flow of molten fiberizable material through the block, a bushing assembly having a bushing block with one or more bores extending through a peripheral region thereof to divert a portion of a supply of molten fiberizable material from a central region of the bushing block to the peripheral region of the bushing block, and a bushing positioned in general registry with the bore of the peripheral region of the bushing block to facilitate the flow of molten fiberizable material to a peripheral region of the bushing is disclosed.
