Patent

CA 2432156

An apparatus for manufacturing a polymer fiber shell from liquefied polymer is provided. The apparatus includes: (a) a precipitation electrode being for generating the polymer fiber shell thereupon; (b) a dispenser, being at a first potential relative to the precipitation electrode so as to generate an electric field between the precipitation electrode and the dispenser, the dispenser being for: (i) charging the liquefied polymer thereby providing a charged liquefied polymer; and (ii) dispensing the charged liquefied polymer in a direction of the precipitation electrode; and (c) a subsidiary electrode being at a second potential relative to the precipitation electrode, the subsidiary electrode being for modifying the electric field between the precipitation electrode and the dispenser.

Appareil pour fabriquer une gaine de fibres polymères à partir d'un polymère liquéfie. L'appareil comprend: (a) une électrode de précipitation servant à former une gaine de fibre polymère à sa surface; (b) un distributeur possédant un premier potentiel par rapport à l'électrode de précipitation, qui génère un champ électrique entre l'électrode de précipitation et le distributeur, le distributeur servant à: (i) charger le polymère liquéfié et former ainsi un polymère liquéfié chargé et; (ii) distribuer le polymère liquéfié chargé en direction de l'électrode de précipitation; et (c) une électrode subsidiaire ayant un deuxième potentiel par rapport à l'électrode de précipitation, l'électrode subsidiaire servant à modifier le champ électrique entre l'électrode de précipitation et le distributeur.
