Title
(EN) CONTINUOUS WIRE DRIVE SYSTEM FOR NEEDLELESS ELECTROSPINNING APPARATUS
(FR) SYSTÈME D'ENTRAÎNEMENT DE FIL CONTINU POUR APPAREIL D'ÉLECTROFILATURE SANS AIGUILLE
Abstract
(EN)
A continuous wire drive system for a needleless electrospinning apparatus, the electrospinning apparatus including an electrospinning enclosure and within which a nanoscale or submicron scale polymer fiber web is formed onto a substrate from a liquid polymer layer coated onto a plurality of continuous electrode wires passing through the electrospinning enclosure. The continuous wire drive system includes a master wire drive drum and a slave wire drive drum, each of the master wire drive drum and slave wire drive drum including a plurality of wire guides, each of the wire guides including a channel or groove for receiving one of the plurality of continuous electrode wires. The continuous wire drive system is external to the electrospinning apparatus, and the continuous wire drive system drives the plurality of continuous electrode wires through the electrospinning enclosure.
(FR)
L'invention concerne un système d'entraînement de fil continu pour un appareil d'électrofilature sans aiguille, l'appareil d'électrofilature comprenant une enceinte d'électrofilature à l'intérieur de laquelle une bande de fibres polymères à l'échelle nanométrique ou à l'échelle submicronique est formée sur un substrat à partir d'une couche de polymère liquide appliquée en revêtement sur une pluralité de fils d'électrode continus passant à travers l'enceinte d'électrofilature. Le système d'entraînement de fil continu comprend un tambour d'entraînement de fil maître et un tambour d'entraînement de fil esclave, chacun du tambour d'entraînement de fil maître et du tambour d'entraînement de fil esclave comprenant une pluralité de guides de fil, chacun des guides de fil comprenant un canal ou une rainure pour recevoir l'un de la pluralité de fils d'électrode continus. Le système d'entraînement de fil continu est externe à l'appareil d'électrofilature, et le système d'entraînement de fil continu entraîne la pluralité de fils d'électrode continus à travers l'enceinte d'électrofilature.
