Apparatus for spinning yarn
Abstract
Abstract r comprising a spinning rotor journaled in a bearing housing and enclosing a spinning chamber having a circumferential groove and a hollow shaft defining its axis of rotation, a feeding device arranged upstream from the spinning rotor for supplying individual fibers from a fiber web and means creating an electrostatic field through which said fibers pass to charge said fibers, said means for providing said electrostatic field being formed of a first electrode comprising said feeding device and a second electrode comprising at least a portion of said spinning rotor, and a source of high voltage, said feed means being arranged so that said charged fibers are impelled toward said spinning chamber in a direction parallel to the axis of rotation of said spinning rotor, electrically conductive means located within said spinning chamber and connected to said second electrode for electrically discharging said fibers and baffle means covering said spinning chamber to prevent rearward movement of said discharged fibers, said fibers being centrifugally deposited in said groove parallel with each other and subsequently spun within said chamber.
