Method and apparatus for making a filament winding amenable to inside payout and having squared-off ends providing optimal volumetric efficiency. The filament crossovers are distributed so as to reduce crossover stacking in one or a few places which can interfere with winding and payout from the finished...http://www.google.com.tw/patents/US5154366?utm_source=gb-gplus-share專利 US5154366 - High density filament winding and method for producing improved crossovers and inside payout
