ABSTRACT:
Each of a plurality of multifilament, resin-impregnated rovings (18) is routed through orthogonally disposed guide rollers (222, 224; 242,244) for compaction to a predetermined width and thickness between the radial faces of a compaction backup roller (250) and a compaction roller (254). The force applied to the compaction roller (254) is varied to assure the dimensions of each compacted roving. The compacted rovings (18) are then routed through a bandwidth adjustment assembly (290) that controls the spacing between adjacent rovings such that they emerge in a side-by-side alignment forming a band (90). The band (90) then passes over the surface of a final deliver roller (296) before being wound onto a rotating mandrel (92) in a band edge-to-edge configuration to form a filament-aligned structure. The structure is then cured, causing the flow of the resin impregnation and forming a unified structure.
