Abstract
Disclosed is a filament winding feed system that collects and collimates strands of composite material (26) from a supply creel (22) and controls the convergence of the strands into a single band (20) at a feed eye (32) as the band is wound about a rotating mandrel (18). The feed eye (32) incorporates a ceramic ring (108) that is rotatably mounted therein. Use of the rotatable ceramic ring (108) provides a durable surface by which strands (26) can pass without causing excessive wear. The heat retention property of the ring (108) is conducive to lubrication of the passing strands without overheating the strands. The rotatable nature of the ring (108) eliminates the problem of strands bunching or twisting as they move in response to changes in the winding direction. Two comb devices are used as control elements. The first comb (24) collects the strands from the supply spools into a parallel spaced-apart relationship. A second comb (30) operates in conjunction with the feed eye to focus the strands into the band (20 ).
