ABSTRACT:
A filament winding machine for winding fibrous strands coated with a resin binder onto a mandrel in a helical pattern to form a tubular article. One end of the mandrel is provided with an extension or sleeve having a smaller diameter than the mandrel, and a wind-off ring is disposed longitudinally adjacent the sleeve. In operation, the fibrous strands are initially wound on the wind-off ring to lock the strand to the ring, and the winding is then transferred to the sleeve and after several turns on the sleeve, the winding is then transferred to the outer surface of the mandrel. The diameter of the mandrel sleeve is correlated with the diameter of the mandrel and the winding angle so that no slippage of the strands occur as they pass from the sleeve onto the mandrel, thereby resulting in minimum scrappage for the wound article.
