Apparatus for producing fibrous structures electrostatically

Apparatus for continuously producing a plurality of individual tubular fibrous structures, which apparatus comprises a plurality of spaced apart fiber collectors, electrostatically charged in use, each of said collectors comprising a rotatable mandrel, and delivery means for delivering fiberizable material towards the collectors, which delivery means comprises a continuous delivery loop path, said collectors being disposed substantially uniformly outwardly of said delivery loop path, a multiplicity of ejection outlets for fiberizing materials spaced apart along the loop path, means for supplying fiberizable material to the ejection outlets, and means for moving the outlets around the loop path to cause, in use, continuous movement of the ejection outlets past the collectors, said collectors further comprising electrostatically charged means in the regions of the ends of the collectors to provide a continuous electrostatic field around the loop path to attract material from the ejection outlets to avoid discontinuity in ejection.
