ABSTRACT:
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 winding. A base wire layer is wrapped onto a mandrel over which a guide is nestingly wound with adjacent guide wire turns spaced apart. The filament first layer is wound nesting in the guide wire spaces, and subsequent filament layers accordingly formed. Each crossing filament turn has an advance in a crossing region substantially aligned with a crossover region in the underlying layer and which in one embodiment is one-half the winding pitch.
