ABSTRACT:
According to the invention, a method and system of injecting material into a wound filament items such as a fiber optic canister is provided. The method is useful with a canister which, when dry wound, has at least one channel formed therein.
In one aspect, the method includes the step of injecting adhesive into the channel to impregnate the canister with adhesive. In another aspect, the method includes the additional step of discharging adhesive from a second channel to remove excess adhesive from the canister. The method may also include the step of circulating air through the two channels to purge excess adhesive and solvent.
