Patent ID: 8342831

Claim:
An electrospinning apparatus for spinning a polymer fiber from a fluid that comprises a polymer, comprising: a plurality of collectors; said collectors are insulated from each other; a potential difference is applied between one of said collectors and an electrode of a jet supply device; said jet supply device delivering a quantity of fluid; said potential difference is applied to a respective one of said collectors, said polymer fiber is drawn to said respective one of said collectors, said potential difference is disconnected from said respective one of said collectors and applied to a next respective collector of said collectors weaving said polymer fiber from said respective one of said collectors to said next respective collector of said collectors, and so on; said polymer fiber is woven from said respective one of said collectors to said next respective collector of said collectors to any other collector or collectors of said collectors and vice versa, once or repetitively; a controller controlling sequence and of which said potential difference is applied to said respective one of said collectors, said next respective collector of said collectors, any other collector or collectors of said collectors being in electrical communication with said jet supply device at least once during a time period.
