Abstract
The invented methods provide a means for reducing or eliminating manual astments that are required during the fabrication (winding) of fiber optic dispensers. This reduction is accomplished through the use of a fiber placement pattern that is permanently generated on the bobbin winding surface. Filaments, such as optical fibers, are precisely guided during the winding of subsequent filament layers by the embedded crossover pattern baselayer. The embedded crossover pattern baselayer is generated by first winding in a given direction a wire of a pre-selected diameter upon the polymer coating on the bobbin surface. The polymer is allowed to cure partially before the wire is unwound and removed. Afterwards a pre-selected optical fiber is wound in the direction opposite that of the wire winding direction thereby creating crossover patterns which are, then, manually adjusted to be in desired locations on the bobbin axis. The optical fiber is removed and the polymer is allowed to cure to a rigid, noncompliant state, thereby generating the embedded crossover pattern baselayer.
